A bacterial biocenosis is a section of soil in which bacteria are in balance with other microorganisms and have a mutual influence on each other, on plants and animals. This environment usually has characteristics of climate, topography, soil, as well as disturbed ecosystems. Bacteria are one of the most important components of the forest organism; they form not only a substrate for plants, but also participate in the basic processes of photosynthesis, respiration, humus formation, and also play a key role in the growth of tree roots. In addition, bacteria play a significant role in the formation of soil, which is an indispensable resource for the life of plants and forest species. Therefore, changes in the bacterial biocenosis can have a significant impact on the living environment of forest biota.
Bacterial biocenosis is a community of living organisms: bacteria and fungi. Evolutionarily relatively young for the biosphere as a separate object of human influence. Microbiocenoses exist in soil and water. If the ecosystem functions normally, then bacteria stabilize it - they act as heterotrophs in the cycle of substances. It is bacteria that are actively involved in the carbon cycle, transforming simple forms of organic compounds into complex ones. Carbon transfer within the cell is carried out only by autotrophic organisms. And on a global scale, it is carried by heterotrophs, also oxidizing large volumes of nitrogen. And all processes of decay in soils and the cells of organisms are the result of the activity of bacterial heterotrophs.
