What microbes break down organic matter in soil and use of microorganism to breakdown the contamination of soil?
There are various microbes that play a crucial role in breaking down organic matter in soil. These include bacteria, fungi, and other microorganisms.
Examples:
In terms of using microorganisms to break down soil contamination, a process known as bioremediation is often employed. Bioremediation involves the use of specific microorganisms to degrade or detoxify contaminants in soil.
Examples:
Decomposition is a biological process that includes the physical breakdown and biochemical transformation of complex organic molecules of dead material into simpler organic and inorganic molecules. These may be the macroscopic organisms such as earthworms and nematodes or microorganisms such as fungus, actinomycetes and bacteria. These organisms breakdown the plant material into soil organic matter. Decomposers break apart complex organic materials into more elementary substances: water and carbon dioxide, plus simple compounds containing nitrogen, phosphorus, and calcium. All of these components are substances that plants need to grow. Organic matter decomposition serves two functions for the microorganisms, providing energy for growth and suppling 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" (humus) fractions. Bacillus subtilis and Pseudomonas fluorescens are examples of decomposer bacteria. Beneficial microorganisms include those that create symbiotic associations with plant roots (rhizobia, mycorrhizal fungi, actinomycetes, diazotrophic bacteria), promote nutrient mineralization and availability, produce plant growth hormones, and are antagonists of plant pests, parasites or diseases. Bacteria are the dominant population of microorganism during all stages of the composting process and are particularly active in the breaking down of the easily degraded organic material whereas the actinomycetes and fungi typically proliferate in the later stages. In fact, just a single teaspoon of compost can contain one billion bacteria. Different types of bacteria have different functions – some produce antibiotics, some are beneficial for human health, while others can cause disease when we're exposed to too much of them.Bioremediation is an effective treatment for agricultural soil pollution. It relies on the ability of microorganisms to remove pollutants. The purpose of this study is to create a consortium based on microorganisms isolated from technogenic sites for further development in the field of soil restoration in agriculture. Microbes able to degrade the contaminant and increase in numbers when the contaminant is present. When the contaminant is degraded, the biodegradative population become declines. The residues for the treatment are usually harmless product including water carbon dioxide and cell biomass.Microbes consume the organic contaminants and bind the less soluble fractions, which can then be filtered off. Toxic ammonia is reduced to nitrogen gas and released into the atmosphere. Beneficial soil microbes perform fundamental functions such as nutrient cycling, breaking down crop residues, and stimulating plant growth. Microorganisms play foremost role in soil formation and soil ecology because they as 'natural soil engineers' regulate the flux of nutrients to plants and prop up nitrogen fixation, and ultimately promote detoxification of naturally occurring inorganic and organic pollutants in soil.
