Rhizobium is Gram-negative soil bacteriathat fix nitrogen and helps plants to observeatmospheric nitrogen. Fungi are the most important of electron donors continues until only CO2 is left to serve nutrient for the plant. They make possible the continued existence of green plants and therefore of animals because the plants are the only source of food for animals. Also mention why the change is happening as it relates to the business. CNOHP). of lakes or in swamps. The role of microorganisms in wastewater treatment helps to treat and purify wastewater and make it less harmful to the environment.

[Microbial allergy and immunotherapy in allergologic practice]. (2016), the microbes are able to enhance the nutrient availability in the soil through the decomposition of organic matter, N fixation, and P and K mobilization.

The nitrogen-fixing bacteria are thus unique in tapping a source of nitrogen not available to most other plants. It moves in the soil rapidly and is acted upon by microorganisms of the category of chemosynthetic autotrophs in the soil.
