Keywords: biotechnology, high technology, development
China is a developing country, and agriculture is the basis for the development of the national economy, which provides people with the basic needs of life. The main role of biotechnology is to improve the health security of our people through the progress of agriculture and medicine. In this sense, China's development of biotechnology should be different from the objectives of developed countries, should have their own characteristics.
1, policy and strategy
(1) Biotechnology should be placed at the top of China's high-tech development plan, because the progress of biotechnology can be transformed agriculture, including grains, fertilizers and livestock.
(2) Priority should be given to the development of agriculture, including agriculture, forestry, animal husbandry and fisheries, followed by new biotechnology products in the fields of medicine and health, light industry and food. The focus of research should be tilted to agriculture. The development of biotechnology should be formed as soon as possible high-tech production system. Research projects should be a limited goal, giving priority to the development of a number of domestic urgent needs, mature technology, economic and social benefits, the country has a certain basis and conditions for new biotechnology products.
(3) the use of modern biotechnology, accelerate the technological transformation of traditional industries, in order to raise the level of technology and production, improve product quality, increase varieties, reduce environmental pollution. To this end, in agriculture, we should use new technologies and traditional technologies combined with the method of strengthening the selection and breeding of fine varieties; in medicine, light industry, the active use of genetic engineering, enzyme engineering and fermentation engineering technology, reform of the traditional production process, in order to improve yields and increase efficiency.
(4) vigorously strengthen the development of biotechnology. For example, vigorously develop new fermentation equipment, which can be used for bacterial culture, can also be used for mammalian cell culture; production of protein and nucleic acid purification instruments and monitoring and analytical instruments, in order to promote the results of scientific research into productivity.
(5) Attention to biotechnology and related areas of basic research. To carry out basic research can provide a theoretical basis for the improvement of existing technologies and the development of new technologies, but also the digestion and absorption of foreign advanced technology and training of talents is an important condition. To maintain the continuity and stability of this policy.
(6) The development and improvement of the necessary biotechnology supporting infrastructure. For example, the establishment of restriction endonuclease and other modified enzymes, isotopes, protein separation and purification and cell culture media production and supply system, as well as the establishment of cell banks, gene banks and biotechnology information base.
(7) Strengthen international academic exchanges, technical cooperation and technology introduction in biotechnology. Establish a number of national key laboratories, equipped with advanced instruments, open to domestic and foreign scientists. The introduction of advanced key technologies from developed countries should be mature technology, but also the domestic national economic construction of urgently needed technology.
(8) To carry out legislative work on biotechnology. This is to prevent the development of biotechnology in the process of possible side effects, especially the operation of recombinant DNA.
2. Forecast and Prospect
From the development trend of biological development and its potential ability to consider, if China's training of personnel, research and development, and funding can be reasonably arranged, China's biotechnology will be in the original fermentation industry on the basis of a new industrial system, in agriculture, and in the development of the industry, and in the agricultural industry, and in the development of the industry. The industrial system, in agriculture will also achieve greater benefits.
2.1 Physiological active substance production
As a pharmaceutical and a large number of peptide substances such as growth factor, insulin, interferon and hepatitis B vaccine, urokinase, etc., at present in our country is still extracted from animal or human tissues in the refining, most of them can not be realized in mass production, the cost is high, and the price is expensive. The application of biotechnology to produce such drugs has been effective research, will be brought to mankind Fuyin.
2.2 Enzyme production
With the development of enzyme catalytic technology and the application of immobilized enzyme reactor technology, the production of enzyme will have greater development. At present, 60% of the world's total enzyme production is protease, mainly used in detergents, tanning and dairy processing. The types and quantity of enzyme preparations in China are not much, and the application market of some enzymes has not been opened. Diagnostic, pharmaceutical and reagent enzymes in China's enzyme consumption accounted for about 10% of the proportion of this development potential, especially the development of enzyme diagnostic cartridges, it is possible to form a new industry.
2.3 Production of antibiotics
China's antibiotic factories produce 50 to 60 types of antibiotics. However, the structure of antibiotic varieties is extremely irrational. In the future, it is possible to focus research and development efforts on the development of antibiotics of the -lactam group. -Lactam antibiotics on the development. Agricultural antibiotics is a big branch of antibiotic industry. In foreign countries are only used as feed additives antibiotics have as many as 18 kinds, along with the great development of China's feed industry, agricultural antibiotics will be emphasized as a new industrial category.
2.4 Amino acids, organic acids and polysaccharides production
There are 18 kinds of amino acids produced by biotechnology, in addition to half of the world's food, medicine, half of them are used as feed additives. The demand for lysine, tryptophan and methionine will increase year by year. China in the development of amino acids for feed started late, vigorously develop the production of feed lysine, tryptophan, methionine will be the key task in the future. At the same time, we should also vigorously develop other medical amino acids.
In order to improve the yield of amino acids, genetic engineering and cell fusion technology to cultivate new strains of bacteria will be strengthened in the future. Immobilized enzyme or immobilized cell technology to produce amino acids may be applied in industry.
The production of organic acids and microbial polysaccharides will see new developments in the future. In particular, the microbial production of xanthobacter gum, pullulan and cyclodextrin and other polysaccharides because of its greater use in the petroleum industry and the food industry, it is likely to be opened up as a new industry.
2.5 Single-cell protein industry
The technology field of single-cell protein has been emphasized because it is related to the treatment and reuse of waste and the provision of protein food for human needs. The production of single-cell protein in China includes baker's yeast, medicinal yeast and feed yeast.
Now with molasses and a variety of industrial wastewater as raw materials for the production of single-cell protein have made a technological breakthrough. Soon there will be molasses, monosodium glutamate waste liquid, alcohol waste liquid production of single-cell protein enterprise groups. China's single-cell protein industry will certainly develop.
2.6 Agricultural and animal husbandry production
Biotechnology in agricultural and animal husbandry production, has been and will continue to show its important role. China has made certain achievements and progress in the application of tissue culture for rapid reproduction, genetic engineering and cell fusion breeding and embryo transplantation, and has bred some excellent new varieties of plants and animals. In the future, we will continue to strengthen our efforts in using new biological technologies to breed new high-yield and high-quality or anti-stress (including drought-resistant, saline-alkaline-resistant and herbicide-resistant) crop varieties and animal breeds, and we will also make new progress in constructing high-efficiency nitrogen-fixing biological systems and cultivating high-efficiency ammonia-fixing strains of microbial organisms. The technology of transferring and dividing animal embryos will also be widely used in the propagation of good breeds. Monoclonal antibodies prepared from hybridomas will be used for rapid diagnosis of crop, animal, poultry and fish diseases.
In addition, the use of biotechnology to protect the environment, purification of industrial wastewater, natural waste and biomass as raw materials for the production of energy and fuel, the use of bacterial leaching ore mining and refining of non-ferrous metals, especially in the field of basic chemistry in the application of biotechnology to create useful products have achieved some results and put forward a number of new research topics, and show a bright future.

Biotechnology thesis 2000 words sample essay two: "contemporary sericulture biotechnology development status overview"
Abstract: In the past 50 years, China's sericulture science and technology has developed rapidly, in the basic theories of molecular biology research, the development and application of silk protein biomaterials, genetic engineering technology of the silkworm, silkworm gender control and specialization of male sericulture technology, insect hormones in the sericulture industry, Artificial control of silkworm metamorphosis development, silkworm nutritional physiology and artificial feed research, silkworm as a bioreactor for the production of recombinant proteins, mulberry cultivation and genetic breeding of new technology development and comprehensive utilization of biological resources of sericulture and mulberry and so on, has made great progress, greatly promoting the sericulture production to the depth and breadth of the expansion. The development of sericulture biotechnology is closely related to the people's livelihood, the development of sericulture biotechnology will certainly promote the development of China's sericulture, sericulture farmers to increase income, drive the development of the silk industry and its related industries, to promote the development of sericulture bioscience, but also for the biological science and education to provide a wealth of resources, so that the traditional sericulture industry glows with vitality.
Reviewing the development of sericulture science in China, and looking forward to the development trend of sericulture science and technology in the world, it can be more profoundly understood: sericulture science is an applied science that provides methods and principles for the silk production related industries (planting mulberry, sericulture, seeding, silk production). Looking to the future, the important task of sericulture scientific research is to further improve the scientific and technological content of sericulture production, so that sericulture from labor-intensive to knowledge-intensive rapid transformation, and this transformation is largely dependent on the progress of basic research in sericulture biology and the development of applied technology innovation.
1 basic theory of molecular biology of silk research
Further clarification of the molecular structure of silk proteins and silk protein gene expression regulatory mechanism, will provide a theoretical basis for the increase in production of silk, improve the quality of silk molecular biology. Floating lubricated mulberry silk clothes are many people's favorite, but let people suffer is that the mulberry silk is very delicate, not wearable, take care of it is also extra troublesome. in November 2014, China's Southwest University scientists cultivate recombinant gene silkworm baby spit out the first time the synthetic silk protein. Among the 16,425 genes in the domestic silkworm, there is one called Fib-H gene, which is a key gene controlling the production of silk protein. Researchers in the germ cells of the silkworm? cut? the Fib-H gene in the germ cells of the silkworm, and the silk glands of the silkworm without the Fib-H gene are called ? empty silk glands? The researchers microinjected a pre-designed artificial silk protein gene, which is similar to the Fib-H gene, into the eggs of silkworms that had their Fib-H gene knocked out, and the eggs with successful transfer of the artificial silk protein gene developed into? The eggs with successful transfer of the artificial silk protein gene developed into baby silkworms. After the successful transfer of the artificial silk protein gene, the eggs developed into "baby silkworms", which spit out silk containing synthetic silk proteins. Through the artificial improvement and redesign of silk fibers, mulberry silk may be like cotton clothes in the future, not only to maintain the comfort of mulberry silk, but also like cotton clothes as wearable, good care.
2 The development and application of new functions of the biomaterials of the silk protein of the silkworm
The silk protein of the silkworm is a kind of biomaterials with good air permeability and moisture permeability, non-toxic, non-irritation, and strong compatibility with the human body. Silk protein can not only be used as artificial skin, blood vessels, tendons, ligaments, bones and teeth and other artificial tissue materials, as well as surgical sutures, contact lenses, corneas, anticoagulants, controlled release of drugs, functional cell culture substrates, immobilized enzyme carriers and biosensors, and other biomedical materials are also in the environmental protection of new materials, cosmetics, health care and nutritional food and other daily life and environmental protection fields are widely used. With the significant progress of the silkworm genome research work, as well as the rapid progress of genetic engineering and biotechnology, the biological function of the silkworm silk protein is expected to be in the military, aerospace, medicine, environmental protection and other fields to get deeper and wider development and application.
3 Genetic engineering technology of the domestic silkworm
The mulberry silkworm is not only an important economic insect, but also one of the model organisms for the study of eukaryotic gene expression regulation. The transfer of exogenous genes into the mulberry silkworm to achieve their expression in the silkworm is ultimately to integrate the exogenous genes into the chromosome of the mulberry silkworm so that stable inheritance is possible and transgenic silkworms can be obtained. Currently, the transgenic reports on mulberry silkworms mainly include: gene transfer between mulberry silkworm strains, gene transfer from other animals into mulberry silkworms, and gene transfer from mulberry silkworms into other animals. For example, Lu Changde, a researcher at the Chinese Academy of Sciences, et al. utilized ? electroporation? method to inject fluorescent protein genes and spider drag silk genes into silkworm eggs, obtaining the spitting out of fluorescent ? Spider silk. The transgenic silkworm spits out fluorescent spider silk. Spider silk in the tow silk is very high strength, very strong elasticity of natural protein fibers, if made into bulletproof vests? The knife is hard to get into? Weaving a parachute firm and durable; produce fluorescent silk can be used to develop natural glow-in-the-dark clothing and a variety of anti-counterfeit labels and so on.
4 silkworm gender control and specialized male technology
Male silkworms and female silkworms, compared with a number of advantages, one is strong and healthy, easy to feed; two is less food mulberry, high feed efficiency; three is a high rate of silk, cocoon silk quality is excellent, can be misty high grade silk. Specializing in male silkworms than the current half of male and female silkworms mixed farming, can substantially improve the production of silk, quality and economic benefits of sericulture. Therefore, the exclusive rearing of male silkworms is known as the most valuable innovative technology after the utilization of one generation of hybrids. The application of sex-linked balanced lethal gene has made great progress, the Russian Academy of Sciences Stronnikov bred mulberry silkworm sex-linked balanced lethal line, on the basis of the transbreeding improvement cultivated a number of male silkworm varieties, male silkworm rate of 99.85%, can achieve the goal of exclusively male sericulture. Specializing in male sericulture will become a major breakthrough in the 21st century to improve the silk production capacity of mulberry silkworms and improve the silk process traits.
5 Insect hormones in the application of sericulture
Molt hormone (MH), juvenile hormone (JH) and juvenile hormone analog (JHA) in the regulation of growth and development of mulberry silkworms, silk production and the production of ultra-fine fibers in the production of raw silk, has made greater progress. For example, the application of juvenile hormone and molting hormone can improve the quality of summer and fall cocoons and better solve the problem of mulberry leaf deficiency. Discovered several kinds of anti-molting hormone active substances, successfully induced three-sleeping silkworms, the development of ultra-fine fiber quality cocoon silk. In addition, the use of anti-young hormone can shorten the silkworm period, improve labor productivity and economic benefits.
6 silkworm metamorphosis and development of human regulation
The human regulation of silkworm metamorphosis and development of human regulation is one of the fundamental problems of the silk industry science, human regulation of silkworm metamorphosis and development of the silk industry's production structure and the overall efficiency of production has a significant impact. Because the silkworm is a fully metamorphosed insect, the pupal period is very short, only 2 weeks, and moth cocoons are not suitable for reeling, the production must be in the pupa before the completion of the acquisition of fresh cocoons and drying work. People want to artificially regulate the metamorphosis and development of silkworm, extend the pupal period, reduce the work pressure and intensity of fresh cocoon acquisition and drying, and even hope that the pupal period of the development of the suspension of the realization of fresh cocoon reeling. Using genetic engineering technology, the carrier with scorpion toxin gene is introduced into silkworm eggs by sperm-mediated method, which is specifically expressed during the pupal stage and kills the silkworm pupa. In this way, not only can solve the contradiction between the fresh cocoon collection and baking and the pupal period is too short, so as to improve the grade of raw silk becomes possible, but also can greatly save the energy required for baking cocoon.
7 Nutritional physiology of silkworm and artificial feed research
The silkworm belongs to the phytophagous insects. In addition to feeding on mulberry leaves, silkworms can also feed on mulberry Tsuga, Asteraceae dandelion, lettuce, elm wild elm and so on. However, it is difficult for silkworms to grow and develop healthily and reproduce their offspring with plant leaves other than mulberry leaves. In the past 40 years on the basis of silkworm feeding behavior and nutritional physiology research, the wide-eating silkworm species selection and low-cost artificial feed design has made great progress, which is possible in the near future, with low-cost artificial feed in the fully automated plant to achieve year-round sericulture, thus promoting sericulture from labor-intensive industry to knowledge-intensive transformation. For example, Japan as early as the 1990s in the 20th century, the successful selection and breeding of low-cost linear planning and design of feed addicted to multiple pairs of wide-feeding silkworm varieties, Japan's other current varieties of artificial feed adaptive selection and breeding, are equipped with good ingestion. China's sericulture industry since the 1990s, in the artificial feed-adapted silkworm varieties and wide-feeding silkworm varieties of selection and breeding has also done a lot of research. Shandong Agricultural University Forestry Department of Sericulture, in recent years, also carried out the selection and breeding of artificial feed-adapted silkworm varieties, and the preliminary selection of a better ingestion of hybrid combinations of wide-eating a wide range of food and wide-eating feed (the main ingredient: mulberry leaf powder 30%, soybean meal powder 25%, and other starch, preservatives, vitamins, inorganic salts, etc.). 8 Sericulture as a bioreactor for the production of recombinant proteins
? The domestic silkworm bioreactor ? , refers to the recombinant baculovirus with the target gene implanted in the pupa of the domestic silkworm for cultivation, the pupa will actively transcribe and translate the implanted gene, naturally generating biologically active substances useful to human beings, and through high and new technology (such as ultra-low-temperature refrigeration, low-temperature drying, high-speed centrifugation, etc.), the biologically active ingredients are extracted and made into the relevant dosage form, in order to meet the treatment of human diseases, prevention and health care needs. The silkworm is easy to raise, low cost, it can synthesize 3 169 mg exogenous protein in 1 day; its hemolymph has the ability to store protein, lymph contains inhibitors of proteolytic enzymes, the purpose of the protein to play a protective role, and exogenous proteins and easy to isolate and purify from the body fluids of silkworms; can also be used as a drug or food additives, silkworms can be used as a drug or food additives by directly grinding. Therefore, the use of silkworm bioreactor production of useful proteins has great superiority. Such as the use of silkworm to produce skin growth factor, hepatitis B vaccine and other high value-added proteins.
9 Mulberry cultivation and genetic breeding of new technology development
Mulberry cross-breeding, mutation breeding and polyploid breeding are effective ways to improve mulberry varieties, but also an important way to improve silk production per unit of area, and the research and application of cellular engineering and genetic engineering will also provide new ways and methods for mulberry breeding. The world's 26 mulberry species, distributed in China at least 15, at present, China's preservation of mulberry varieties of resources amounted to 2,600, has been selected to adapt to different environmental conditions, cultivation techniques, sericulture requirements and other uses of the excellent mulberry varieties of more than 50, of which the most cultivated area is the Rusang system of the Lotus Leaf White, Tongxiang Qing, the Tuan head of the Lotus Leaf White, Husang 197, Yuko 2 and other varieties. Mulberry cultivation mainly adopts low and dense planting, three-dimensional cultivation management mode, improve the mulberry leaf yield, quality.
10 comprehensive utilization of sericulture biological resources
China's sericulture by-products processed into many products have entered the industrial production stage, such as the use of mulberry leaves, mulberry fruit to produce mulberry tea, mulberry cream, mulberry wine, extract phytol, chlorophyll, carotene, etc.; the use of silkworm pupae to prepare pupal protein powder and peptides, separation of antimicrobial proteins and the production of induced biologically active proteins, the production of silkworm pupa Amino acids and amino acid complexes, the extraction of silkworm chrysalis oil and chitosan, the development of silkworm chrysalis protein fiber, silkworm chrysalis cordyceps, etc.; the use of waste silk research and development of silk pigment powder, silk pigment cream, silk pigment liquid, silk pigment cleansing milk, shampoo and conditioning agent and other beauty and skin cosmetics. Not only improve the comprehensive benefits of sericulture production, but also improve the added value of sericulture products, change the purpose of sericulture production and management, bigger and stronger sericulture industry, so that sericulture better benefit mankind.

Biotechnology essay 2000 words sample essay III: "Try to talk about junior high school biology science and technology innovation and practical activities"
Abstract Biology is an important part of modern science and technology, so biotechnology activities bear the cultivation of young people's spirit of innovation, creativity and hands-on practical ability and other tasks, it is more to cultivate Young people love nature, understand and care about ecological protection, understand the relationship between biology and agriculture, biology and medicine, biology and industry and environmental protection, etc., the primary way, it is also mining and cultivate scientific and technological research talents in the field of life sciences, for the development of China's various undertakings to prepare for the power. Biotechnology innovation and practice activities have all the characteristics of science and technology innovation and practice activities, and occupy a large proportion of science and technology innovation and practice activities in various disciplines. I use the action research method of planning, action, observation, reflection of the four processes, the students are more confused about the selection of the topic link, to take the form of centralized training, case study, tracking survey to solve the practical problems encountered, and in a timely manner to sum up the experience and accumulation of case material, and achieved better results.
Keywords scientific and technological innovation; practical activities; subject research
Today's world. The competition between countries is very fierce, the focus of its competition in science and technology competition, and the core of the competition in science and technology is the competition of talent. The standard for measuring talents is to look at their innovative ability or innovative talent, so the Party Central Committee proposed that the construction of innovative countries, the core is the cultivation of innovative talents.
I. Definition of relevant concepts in junior high school biology science and technology innovation practice activities
Biology is an experimental discipline, focusing on the harmonious development of man and nature, and closely linked to daily life. Biological science and technology innovation practice activities in schools can not only give students the opportunity to practice, exercise their hands-on ability, enhance their sense of social responsibility and social practice ability, but also cultivate students' scientific habits of mind and good cooperation spirit. Realize the goal of shaping personality, improving scientific literacy and innovation.
Second, the exploration and practice of the topic selection stage
According to the "full-time compulsory education biology curriculum standards", "the students should be able to learn more about biology. The concepts of "oriented to all students, improve biological scientific literacy, and advocate inquiry learning" have been adopted by the author of this book. To solve the practical problems encountered in this activity, in order to provide certain reference for science and technology education and the majority of front-line teachers of science and technology activities, and to accumulate certain practical paths and methods for science and technology innovation practice activities.
Before carrying out practical activities in science and technology innovation, the author has made a questionnaire survey of students, 65.38% of students believe that the selection of the link is the most confusing, difficult to select the subject into the impact or constraints? The subject of research? The bottleneck to carry out. I decided to use action research method to solve the problem. Generally speaking, action research includes four links: planning, action, observation and reflection.
In the development of the overall implementation plan should also consider the plan of action steps. The first round of action, and monitoring, to understand its effect, according to the monitoring of the information obtained, analyze the shortcomings, based on which to modify the overall plan, especially for the next round of action steps to make adjustments. Specific action research steps are as follows:
(1) Problems to be solved. After the accumulation of knowledge, students have already selected some topics, but the selection of topics is too blind, not clear which topics others have done, what kind of topics they can do, and how to present the research results in a scientific way.
(2) Analysis of the causes of problem formation. Students' topics mainly come from daily life, to find and ask questions in this kind of habitual phenomenon, it requires students to observe carefully, think actively, and be able to find the unusual in the unusual phenomena.
(3) Designing countermeasures and action programs. Utilizing the publicity position of science lectures and the radiation function of typical cases, students are inspired to pay attention to the people and things around them, select topics from life, and are guided to determine the direction of research on the subject.
(4) Action reflection. From the list of submitted topics, we found that the popularization of science lectures played the expected role. 70.5% of the selected topics came from students' lives. It shows that students have been consciously paying attention to life. However, the problems are the angle of topic selection, the size of the scope of the topic selection, and the feasibility of the study.
(5) A new round of action research program. Take the method of individual counseling, specific problems and specific analysis, to understand the starting point of each topic development, research plan and other details, to help students find the direction and angle of research and entry point, narrow the scope of research, through the decomposition, refinement, improvement, synthesis, refinement of the feasibility of a strong research topic.
(6) A new round of action implementation and monitoring. For the selection of topics with too large a scope, the author uses the method of decomposition and refinement.
(7) Action research stage evaluation and summarization. By comparing the before and after the topic name analysis found that the modified topic name is more precise and specific, and students are clear about the research direction, research focus and entry point. Teachers can also quickly grasp the relevant information about the topic from the topic name.
After teachers and students *** with the efforts of our school science and technology innovation practice group *** produced 24 works, all recommended to participate in the fifth Hebi City Youth Science and Technology Innovation Competition, 24 works have won municipal awards. Among them, the first prize 4, second prize 7, third prize 13.
Third, to carry out the activities of the recommendations
(1) Encourage students to use a variety of ways to select the topic. Biotechnology innovation and practice activities research topics related to the discipline is very rich, including botany, zoology, microbiology, ecology, environmental science and so on.
(2) Tap into the available educational resources. We should take into account the local conditions and dig deeper into the educational resources. We can consider what are the available resources in the school and the surrounding community, and strive for the support of the society and parents.
(3) Improve the scientific research quality of biology teachers. Biology teachers should participate more in the training of scientific and technological activities at all levels, read more books, newspapers and magazines on scientific research, pay more attention to life and society, and collect more relevant cases to stimulate students' interest in innovation. Only when teachers themselves have the ability to conduct scientific research can they cultivate good scientific research quality in their students.
