Why are there bacteria, and what are bacteria?

Because bacteria have an indispensable role in bacteria that are both useful and harmful to the environment, humans and animals. Some bacteria become pathogens, causing tetanus, typhoid, pneumonia, syphilis, cholera, and tuberculosis. In plants, bacteria cause leaf spot, fire blight, and wilting.

Infection can be carried out by contact, airborne transmission, food, water, and infected microorganisms. Pathogens can be treated with antimicrobials, which are divided into bactericidal and bacteriostatic types. Bacteria are often used in conjunction with yeasts and other types of fungi to ferment foods, such as in the traditional vinegar manufacturing process, where acetobacters in the air are used to turn wine into vinegar.

Other foods made with bacteria include cheese, kimchi, soy sauce, vinegar, liquor, yogurt, etc. Bacteria are also capable of secreting a variety of antibiotics, such as streptomycin, which is secreted by Streptomyces. The ability of bacteria to degrade a variety of organic compounds is also commonly used to remove contamination, known as bioremediation.

For example, scientists use methanotroph to break down trichloroethylene and tetrachloroethylene contamination in Georgia, USA. Bacteria also have a great influence on human activities. On the one hand, bacteria are the causative agents of many diseases, including tuberculosis, gonorrhea, anthrax, syphilis, plague, trachoma and other diseases.

However, humans also often use bacteria, such as the production of cheese and yogurt, the manufacture of some antibiotics, and the treatment of wastewater. In the field of biotechnology, bacteria are also widely used.

Why you!? Where did humans come from without bacteria....

The bacteria are thinking: Why is there anyone?

Bacteria are small organisms that are imperceptible to the naked eye, widely existing in nature, and are one of the main groups of organisms. It belongs to the bacterial domain. It is also the most abundant group of all organisms, with an estimated total of about 5,10,30 individuals.

The shapes of bacteria are quite varied, mainly globular, rod-shaped, and spiral-shaped.

The bacteria were first discovered by the Dutchman Antonie vanleeuwemhoek (1632-1723) on the tartar of an elderly man who had never brushed his teeth, but it was thought to be a natural occurrence. It was not until later that Pasteur used gooseneck bottle experiments to point out that bacteria are produced by bacteria already in the air, not by themselves, and invented the "pasteurization method", which was hailed as the "father of microorganisms" by later generations.
