What is the use of microorganisms to degrade the pollutants and role of microbial communities in the formation and decomposition of soil organic matter?
Microbial degradation or biodegradation is the use of microorganisms to breakdown or degrade, detoxify or transform environmental pollutants. Biological decomposition of various substrates is performed by a large number of microorganisms including bacteria, fungi, protozoa, etc. Bioremediation is a process that uses mainly microorganisms, plants, or microbial or plant enzymes to detoxify contaminants in the soil and other environments. Microbial turnover forms the backbone of soil organic matter (SOM) formation and it has been recently proposed that SOM molecular complexity is a key driver of stability. Despite this, the links between microbial diversity, chemical complexity and biogeochemical nature of SOM remain missing.
Microbial Communities Influence Soil Dissolved Organic Carbon Concentration by Altering Metabolite Composition. Rapid microbial growth in the early phase of plant litter decomposition is viewed as an important component of soil organic matter (SOM) formation. Soil organisms, including micro-organisms, use soil organic matter as food. As they break down the organic matter, any excess nutrients are released into the soil in forms that plants can use. Soil microbial communities directly affect soil functionality through their roles in the cycling of soil nutrients and carbon storage. Microbial communities vary substantially in space and time, between soil types and under different land management.

Microbial communities vary substantially in space and time, between soil types and under different land management. Due to their close proximity to plant roots, soil microbes significantly affect soil and crop health. Some of the activities they perform include nitrogen-fixation, phosphorus solubilization, suppression of pests and pathogens, improvement of plant stress, and decomposition that leads to soil aggregation. They must obtain these through saprophytic or parasitic associations with their hosts which implicates them in many decomposition processes. Two major groups of fungi have been identified as being linked to cadaver decomposition: ammonia fungi. Post-putrefactive fungi.Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. This can involve either aerobic or anaerobic micro-organisms that often use this breakdown as an energy source.
Organic matter decomposition serves two functions for the microorganisms, providing energy for growth and supplying carbon for the formation of new cells. Soil organic matter (SOM) is composed of the "living" (microorganisms), the "dead" (fresh residues), and the "very dead” fractions.

Decomposition of organic matter is a process, which includes mostly physical breakdown and biochemical transformation of complex organic molecules into simpler organic and inorganic molecules. Microorganisms are essential to soil formation and soil ecology because they control the flux of nutrients to plants promote nitrogen fixation, and promote soil detoxification of inorganic and naturally occurring organic pollutants. Microorganisms are act as a significant pollutant removal tools in soil, water, and sediments; mostly due to their advantage over other remediation procedural protocols. Microorganisms are restoring the original natural surroundings and preventing further pollution. Due to their close proximity to plant roots, soil microbes significantly affect soil and crop health. Some of the activities they perform include nitrogen-fixation, phosphorus solubilization, suppression of pests and pathogens, improvement of plant stress, and decomposition that leads to soil aggregation.
