Bacteriology Reasearch Development Microbiology Branch

Research and development in Bacteriology Subject

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

The main role of bacteriology is to study the immunity of the human body.

What is the Definition of Bacteriology?

Bacteriology Definition: In 1676, Levin Hook first discovered that the bacteria in the oral cavity were called "small creatures" at that time. In 1861, Pasteur's experiments with his famous gooseneck flask strongly proved the presence of bacteria in the air. According to his research on fermentation, he pointed out that there are many kinds of bacteria in the air. Their life activities can cause the fermentation of organic matter and produce various useful products. Some products can also be used for the subsequent fermentation of other bacteria. Some products.

What  is Bacteriology Research Object?

Pathogens of humans and animals also exist in the air, which can cause various diseases. In order to eliminate bacteria, Pasteur created the pasteurization method in 1886. In 1877, the British chemist Tyndall established the intermittent sterilization method or the Tin sterilization method. 

Aseptic surgery was founded in 1876. In the same year, the German Koch isolated anthrax bacteria and proposed the famous Koch law. In order to understand the difference between Vibrio cholerae and other vibrio indistinguishable in morphology, he conducted physiological and biochemical researches, which led to the first development of medical bacteriology.

Around 1880, Pasteur developed vaccines for chicken cholera, anthrax, and swine erysipelas, laying the foundation for immunology. Koch first used the plate method to obtain single colonies of anthrax, confirming that the morphology and function of the bacteria are relatively constant. 

Since the initial victory of the monomorphism theory, a bacterial classification system based on morphological size has been established, and then the physiological and biochemical characteristics are used as the basis for classification, which gradually enriches the content of bacterial taxonomy.

In the last 20 years of the nineteenth century, the development of bacteriology went beyond the scope of medical bacteriology, and industrial bacteriology and agricultural bacteriology were quickly established and developed. 

From 1885 to 1890, Vinogradsky was formulated into a pure inorganic medium, and autotrophic bacteria (nitrifying bacteria, sulfidizing bacteria, etc.) were separated using a silica gel plate. A "rich culture method" was also developed to easily meet Of bacteria are selected from the natural environment.

What is the Historical Development of Bacteriology?

Bacteriology History and Development: From 1889 to 1901, Byerlink successfully isolated rhizobia and nitrogen-fixing bacteria, confirming the role of bacteria in material transformation, improving soil fertility and controlling plant diseases. 

In the early 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 roughly the same as the glycolysis of vertebrate muscles. The growth factor needs are basically the same as the vertebrate needs for vitamins.

In 1943, Delbrück analyzed the 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.

In E. coli After making insulin, in 1980, Gilbert used bacteria to make human interferon, thus pushing the research of bacteriology to the level of molecular biology.

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