Microbiology research methods and techniques are:
Microscopy, pure species culture technology, aseptic technology, pure species isolation and purification technology and microbial preservation technology.
Microscopy (microscopy): microscopy is the use of optical systems or electronic optical systems equipment, observation of the naked eye can not distinguish the morphology and structure of small objects and their characteristics of the technology. Including: ① the basic principles of various microscopes, operation and application of technology; ② microscope sample preparation technology; ③ observation results of the record, analysis and processing technology.
Pure culture: pure culture is the most important is in the physiological study of microorganisms, the method is to rely on sterilization and isolation, by Pasteur (L. Pasteur) and Koch (R. Koch) established. In nature, there are culture conditions that are very difficult, especially for organisms with close **** biological relationships and organisms that undergo parasitic nutrition; there are also organisms for which pure culture is theoretically impossible. Pure culture - in microbiology, the progeny obtained from a single cell or a group of identical cells that have been propagated in culture, is called a pure culture.
Aseptic technique: aseptic technique is a series of operation techniques in medical care operation process, to keep the aseptic objects, aseptic area is not contaminated, to prevent pathogenic microorganisms from invading the human body. Aseptic technique (aseptic technique) refers to the implementation of medical, nursing technology, to prevent all microorganisms from invading the organism and to maintain sterile goods and sterile area is not contaminated operation technology and management methods.
Purification: purification is the process of separating a mixture of polysaccharides into a single polysaccharide. In strain identification, the microorganisms used are generally required to be pure cultures. The process of obtaining a pure culture is called isolation and purification.
