The basic structure of bacteria is the structure that all kinds of bacteria have, including cell wall, cell membrane, cytoplasm and nucleoplasm. Basic forms present different forms due to different types, as follows:

1, cocci Coccus is a spherical or elliptical bacterium with a diameter of 0.5 ~ 1 micron.

2. Bacillus. Rod-shaped bacteria are called bacilli, and there are often short rod-shaped or rod-shaped bacteria with similar length and width, such as Brevibacterium methanogenes, and rod-shaped or long rod-shaped bacteria with different length and width, such as Bacillus subtilis and Clostridium.

3. Spirillum: Spirillum is called Spirillum, which is generally 5 ~ 50 microns long and 0.5 ~ 5 microns wide.

Application of extended data bacteria;

Bacteria are usually used in fermented food together with yeast and other kinds of fungi. For example, in the traditional manufacturing process of vinegar, acetic acid bacteria in the air are used to convert wine into vinegar. Other foods made by bacteria include cheese, pickles, soy sauce, vinegar, wine, yogurt and so on. Bacteria can also secrete a variety of antibiotics, for example, streptomycin is secreted by hyphomycetes.

The ability of bacteria to degrade many organic compounds is often used to remove pollution, which is called bioremediation. For example, scientists use methane-oxidizing bacteria to decompose trichloroethylene and tetrachloroethylene pollution in Georgia, USA.
