How Microbes are used to degrade pesticides?

How Microbes are used to degrade pesticides?

Many chemical pesticides were analogs of natural compounds, and some microorganism had the enzymes to degrade them. They could be used as a source of microbial nutrients and then be degraded to inorganic matters, carbon dioxide, and water by microorganism.

Which one of the following microbes can degrade pesticide?

Some pesticides are readily degraded by microorganisms, others have proven to be recalcitrant. A diverse group of bacteria, including members of the genera Alcaligenes, Flavobacterium, Pseudomonas and Rhodococcus, metabolize pesticides.

What can be degraded by microbes?

Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons ( …

Which are the microbes that destroy the chemical pesticides?

Which are the microbes that destroy the chemical pesticides in soil. Lot of microbial organisms, such as bacteria, fungi, actinomycetes, algae and other microbial strains are known to degrade the pesticides and they are extracted naturally from the soil and sewage.

What are the three major ways in which pesticides are degraded in or on soil?

Three types of pesticide degradation are microbial, chemical, and photodegradation. Microbial degradation is the breakdown of pesticides by fungi, bacteria, and other microorganisms that use pesticides as a food source. Most microbial degradation of pesticides occurs in the soil.

Which bacteria is used in bioremediation?

Below are several specific bacteria species known to participate in bioremediation.

  • Pseudomonas putida.
  • Dechloromonas aromatica.
  • Deinococcus radiodurans.
  • Methylibium petroleiphilum.
  • Alcanivorax borkumensis.
  • Phanerochaete chrysosporium.

How does microbial degradation occur?

The microbial organisms transform the substance through metabolic or enzymatic processes. It is based on two processes: growth and cometabolism. In growth, an organic pollutant is used as sole source of carbon and energy. This process results in a complete degradation (mineralization) of organic pollutants.

Which are the microbes that destroy the chemical properties in soil?

6. Biodegradation of chemical pesticides in the soil is carried out especially by worms, fungi, and bacteria as they use it as a food source. 7. Bacteria responsible for biodegradation are Flavobacterium, Azotobacter species, Pseudomonas, Acetobacter, Burkholderia, etc.
