“…In another example i.e. lindane [18], endosulfan [19,20], DDT [21] and monocrotophos [22,23], the microbes and/or enzymes were isolated and identifi ed. Genetic studies of microbial degradation indicates that the plasmids are the main place for the gene of interest usually spread throughout the microbial community.…”

Biodegradation is a natural process, where the degradation of a xenobiotic chemical or pesticide by an organism is primarily a strategy for their own survival. Most of these microbes work in natural environment but some modifi cations can be brought about to encourage the organisms to degrade the pesticide at a faster rate in a limited time frame. This capability of microbe is some times utilized as technology for removal of contaminant from actual site. Knowledge of physiology, biochemistry and genetics of the desired microbe may further enhance the microbial process to achieve bioremediation with precision and with limited or no scope for uncertainty and variability in microbe functioning. Gene encoding for enzyme has been identifi ed for several pesticides, which will provide a new inputs in understanding the microbial capability to degrade a pesticide and develop a super strain to achieve the desired result of bioremediation in a short time.

“…The presence of additional carbon sources can shorten the time taken to reach maximum growth, as shown in a study where growth of F. oryzihabitants and P. aeruginosa grown on different carbon sources supplemented with 50 mgL -1 DDT reached a maximum after 24 to 48 hours of incubation at 30°C. The study achieved complete degradation of DDT at 15 mgL -1 showing inhibitory effects at 50 mgL -1 [25].…”

There is a growing interest in the bio-application of microorganisms from the gut of earthworms on the biotransformation of persistent and toxic pollutants during vermifiltration. Earthworms harbor beneficial microbes in their gut which symbiotically aid in biodegradation of pollutants in their drilosphere. Dichlorodiphenyltrichloroethane (DDT) is an example of polychlorinated hydrocarbons and metabolites thereof that are persistent in the environment and are toxic to humans and animals. This study aimed at isolating and identifying 4,4 DDT degrading microorganisms in the gut of Eisenia fetida acclimatized to sewage. Five pure isolates obtained from gut contents were cultured in MSM supplemented with 15 mgL -1 DDT followed by glucose yeast extract agar sprayed with 1% 4,4 DDT in ether (v/v). Two pure isolates positive for 4,4 DDT biodegradation were inoculated on MSM containing 15 mgL-1 4,4 DDT. The resulting metabolites were identified using Gas Chromatography. The positive isolates were identified using 16S rRNA gene analysis as belonging to the Rhodococcus genus and the Bacillus genus, exhibiting 88.36% and 85.22% 4.4 DDT degradation respectively. The study demonstrated DDT-degradation by bacteria from the gut of E. fetida. These findings can be useful in optimization of vermifilters for biodegradation of DDT and other xenobiotics.

“…Abundance and distribution of potential microbes and functional genes associated with pentachlorphenol anaerobic mineralization in a continuous flow reactor was studied by Li et al (2016) The organochlorine compounds undergo degradation through two major pathways, reductive dechlorination that takes place under anaerobic conditions, and dehydrochlorination, occurring aerobically. Several bacterial genera such a Klebsiella (Kwon et al, 2005), Alcaligenes (Don and Pemberton, 1981) Staphylococcus (Sonkong et al, 2008), and Pseudomonas (Barragan-Huerta et al, 2007) carry out the reaction. The ability to degrade organochlorine has been documented in different genera of fungi.…”
