One of the most important effects of microorganisms on human beings is the prevalence of infectious diseases.
There are many kinds of microorganisms, some of which are corrupt, that is, they cause bad changes in food odor and tissue structure.
Microorganisms can cause diseases, which can cause food, cloth, leather and other moldy rot.
Benefits:
1. Antibiotics in microorganisms saved countless lives in World War II, and many modern microorganisms can also ensure everyone's health.
2. Microorganisms are widely used in industrial fermentation to produce ethanol, food and various enzyme preparations.
3. Microbial metabolites can be widely used in agricultural production as natural microbial pesticides.

Maximum microorganism
1985, Fishelson, Montgomery and Myrberg discovered a microorganism named surgeonfish, which was the largest microorganism found in the world at that time.
It looks like a cigar, about 200 ~ 500 microns long, up to 600μm at the longest, and its volume is about 654.38+00000 times that of Escherichia coli. This microorganism can be detected directly with the naked eye without microscope observation.
At present, the largest microorganism is a spherical bacterium discovered by Heidi Schulz in 1997 in the marine sediment soil off Namibia, with a diameter of about100 ~ 750μ m. ..
