What is the role of microbes in reducing environmental pollution & improving environmental quality & microbes play in the cycling of nutrients?
Microbes are used to clean up pollution treatment in processes known as 'bioremediation'. Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. Microorganisms and fungi break down wood and return carbon to the biogeochemical cycles. If these organisms become absent, carbon would accumulate in the wood, where it could not be recycled into the environment. The fixation of nitrogen is dependent on microorganisms mostly through biological nitrogen fixation. Microorganisms help in cleaning up the environment. They decompose dead and decaying matter from plants and animals; convert them into simpler substances which are later used up by other plants and animals. Thus, they are used to breakdown harmful substances.
Soil bacteria promote the health of our crops by increasing drought tolerance, protecting plants from disease and providing nutrients necessary for growth. Attention to the microbial sciences can help to stop land degradation and the loss of biodiversity in water, soil, land and air.Soil microbes play an important role in nutrient recycling. They decompose organic matter to release nutrients. They are also important to trap and transform nutrients into the soil, which can be taken up by plant roots. Nutrient cycling rate depends on various biotic, physical and chemical factors. In forest environments, the nutrient cycle involves animals, plants, fungi and bacteria living above- and below-ground as well as mineral components of soil, dead leaves and wood, and water from rain and snowfall. Microbes are used to clean up pollution treatment in processes known as 'bioremediation'. Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. Help of microbes can be taken to reduce soil contamination. The removal of soil contamination with the help of microbes is called bioremediation. This is usually achieved by bio-augmentation of soil flora. Beneficial microbes such as rhizobacteria and mycorrhizal fungi can help plants to 'deal' with pathogens and herbivorous insects as well as to tolerate abiotic stress.
