What are the benefits and harms of bacteria

The existence of bacteria is not good for the human body. We must do a good job of preventing bacteria in our daily lives. In fact, some bacteria are good for the body, while some bacteria are not good for the body at all and will only cause unnecessary trouble. Therefore, we need to understand clearly the advantages and disadvantages of bacteria.

Bacteria have both beneficial and harmful effects on the environment, humans and animals. Some bacteria become harmful again. Some bacteria are pathogens that cause tetanus, typhoid, pneumonia, syphilis, cholera, and tuberculosis. In plants, the bacteria causes leaf spot, fire blight, and wilt. Modes of infection include contact, airborne transmission, food, water and carriers of bacteria. Pathogens can be treated with antibiotics, which are divided into bactericidal and bacteriostatic types.

People tend to think badly of bacteria. It turns out that most of the bacteria are red-faced heroes, playing the role of immune barrier and nutrition. Finding ways to take in some beneficial bacteria, such as drinking yogurt containing bifidobacteria, will be very beneficial to your health.

Bacteria are often used together with yeast and other types of fungi to ferment foods. For example, in the traditional production process of vinegar, acetic acid bacteria (Acetobacter) in the air are used to convert wine into vinegar. Other foods made using bacteria include cheese, kimchi, soy sauce, vinegar, wine, yogurt, etc. Bacteria can also secrete a variety of antibiotics, for example, streptomycin is secreted by Steptomyces.

The ability of bacteria to degrade a wide range of organic compounds is also often used to clean up pollution, known as bioremediation. For example, scientists used methanotrophs to break down trichloroethylene and tetrachloroethylene pollution in Georgia, USA.
