Which microbes are used to degrade pollutants and use of microorganisms in the remediation of polluted soil and water?
Several microorganisms, including fungi, bacteria and yeasts are involved in biodegradation process. Algae and protozoa reports are scanty regarding their involvement in biodegradation. Bioremediation is a natural process, which relies on bacteria, fungi, and plants to remove, reduce, degrade, or immobilize environmental pollutants from soil and water, thus restoring contaminated sites to a relatively clean nontoxic environment.
Bioremediation can be achieved with the use of microorganisms which depends on the metabolic potential of the microorganisms to degrade environmental pollutants and change them to innocuous forms through redox processes. Microbes digest organic waste by stealing its oxygen, altering the chemical makeup of the material into a less environmentally damaging matter. Microbes naturally facilitate the breakdown of organic material that is an essential process in the life cycle. Because it is their naturally evolved function, microbes are very good at facilitating decomposition. These chemicals are finally dumped in soil and end up contaminating the soil. Help of microbes can be taken to reduce soil contamination. The removal of soil contamination with the help of microbes is bioremediation. This is usually achieved by bio-augmentation of soil flora.
Just identify the pollutants and clasify them. you can acclamatise the microorganisms species that can use that pollutants as food. Then use the local remidiation to the soil by spreading those acclamtaised organisms with taking care of the environmental factors. This is just a simple answer. You need to read more about environmental microbiology.
The microbes simply eat up contaminants such as oil and organic matter convert them and then let off carbon dioxide and water. The process uses naturally occurring bacteria, fungi or plants to degrade substances that are hazardous to human health or the environment. Removal of soil contaminants by microorganisms and the potential mechanism and heavy metals are adsorbed and fixed on the cell surface by microorganisms. Highly toxic metallic elements can be converted to less or non-toxic substances by redox reactions. Bioremediation is used to clean up water, soil, oil, and other such mediums. The organisms like bacteria, fungi completely degrade or breaks down the pollutants and uses it as its energy source and release by-products that are non-toxic and harmless. 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. Microbes digest organic waste by stealing its oxygen, altering the chemical makeup of the material into a less environmentally damaging matter. The aerobic bacteria in the sludge digest the organic material around them in order to reproduce and grow, and change the chemical makeup of the sludge, oxidizing ammonia into nitrate and nitrite in a process as nitrification. Bacteria, archaea and fungi are typical prime bioremediators. The application of bioremediation as a biotechnological process involving microorganisms for solving and removing dangers of many pollutants through biodegradation from the environment. Various microorganisms can degrade environmental pollutants with promising skills like bacteria, fungi, algae, and protozoa. Certain parameters must be established to provide the highest biodegradation rate of degradable microorganisms under the optimum conditions.
