Describe the importance of bacteria for man and nature.

In the middle of the XX century. a person, using knowledge of the science of microbiology, developed a number of technologies, thanks to which, using microbes, he began to create valuable products for him industrially. New industries have emerged – the microbiological production of feed protein, amino acids, polysaccharides, organic acids, enzyme preparations, vitamins, drugs, biological plant protection products, growth stimulants, etc. The list of used biological species and strains of bacteria, mycelial fungi and yeast has expanded . Using genetic engineering through microbiological synthesis in industry, insulin, interferon, growth hormones and a number of other expensive drugs for treating people began to be obtained.
Carrying out the processes of mineralization of organic deposits, microorganisms return to the atmosphere the carbon dioxide necessary for photosynthesis, and also, destroying the organics of dead bodies, convert all substances into a mineral form available for assimilation by plants. Soil fertility depends on the active life of microorganisms. At the same time, they act as the orderlies of the planet, as they free the environment from the accumulation of dead bodies of plants and animals. In addition, the microbial population, and especially bacteria, frees the ground air and soil, water in reservoirs from toxic compounds such as ammonia, hydrogen sulfide, methane, carbon monoxide, oil products and others. Denitrifying bacteria play an important role in maintaining the planet’s ozone screen protecting all life from intense solar radiation.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
