Bacteriology is a branch of microbiology. It mainly studies the morphology, physiology, biochemistry, ecology, genetics, evolution, classification and application of bacteria.

In 1676,

There are also humans and animals in the air.

From 1889 to 1901, Bayerinck successfully isolated rhizobium and nitrogen-fixing bacteria, confirming the role of bacteria in material transformation, improving soil fertility, and controlling plant diseases. At the beginning of the 20th century, bacteriologists made great progress in studying infectious pathogens, immunity, chemical drugs, and chemical activity of bacteria. They basically confirmed that the fermentation mechanism of bacteria is generally the same as the glycolysis of vertebrate muscles. The growth factor requirements are also largely consistent with the vitamins needs of vertebrates.

In 1943, Delbrück analyzed mutants of E. coli; in 1944, Avery found that the transformation in pneumococcus was determined by DNA; in 1957, Kinoshita produced amino acids by fermentation; E. coli was used After making insulin, Gilbert produced human interferon with bacteria in 1980, which pushed the research of bacteriology to the level of molecular biology.

Bacteria have the characteristics of small size, fast reproduction, strong vitality, many species, and easy mutation. They can be researched and produced under the conditions of artificial control. They are important research tools in modern biology and other disciplines.
