How are xenobiotics degraded?
Sequential Bioremediation: In the degradation of several xenobiotics, both aerobic and anaerobic processes are involved. This is often an effective way of reducing the toxicity of a pollutant. For instance, tetra chloromethane and tetrachloroethane undergo sequential degradation.
Why is it hard to degrade a xenobiotic compound?
Biodegradation of naturally occurring organic compounds follows their synthesis. In contrast, man-made compounds, also known as xenobiotics, are often refractory to degradation. The main reason is that they cannot be recognized by naturally present organisms and therefore do not enter common metabolic pathways.
How microbes can be used for degradation of xenobiotic?
Microorganisms potentially utilize xenobiotic contaminants as carbon or nitrogen sources to sustain their growth and metabolic activities. Diverse microbial populations survive in harsh contaminated environments, exhibiting a significant biodegradation potential to degrade and transform pollutants.
Which of the following is the best method to degrade xenobiotic compounds?
Which of the following is the best method to degrade xenobiotic compounds? Explanation: Microbial degradation is the best method to degrade xenobiotic compounds founds in disposal pits, sewage treatment plants etc., as the microorganisms are used to degrade xenobiotic compounds is the best method.
Which of the following is used in biodegradation of xenobiotics?
Explanation: Enzymes are the biological compounds that are used in bio degradation of xenobiotics whereas Chemicals might help in degradation but are harmful to the environment, physical sorting is tedious hence, not effective and poly-cyclic aromatics hydrocarbons are environmental pollutants.
What are xenobiotic degrading bacteria?
Endophytic bacteria involved in xenobiotic degradation. The degradation of xenobiotics by microbes is an evolutionary trait by which microbes survive in the presence of toxins utilizing them as carbon, phosphorus, sulfur, or nitrogen source (Tétard-Jones and Edwards, 2016).
Can plants degrade xenobiotic compounds?
Plants have the inherent capacity to degrade xenobiotic pollutants, but they generally lack the catabolic pathway to provide complete degradation, i.e. mineralization, relative to microbes.
What is important in xenobiotic degradation?
Xenobiotic degradation during biological wastewater treatment can be established or enhanced by bioaugmentation – the addition of either (1) bacterial strains carrying chromosomally encoded genes required for the biodegradative pathway or (2) catabolic genes located on mobile genetic elements such as plasmids or …
