“…After, understanding the gene of interest and enzyme involved, the Superbugs can be created to achieve the desired result at fast rate in short time frame. Lal et al [25] has reviewed the degradation of HCH and distribution of lin gene in Sphingomonads. S. indicum B90A was found to contain two non-identical linA genes (designated as linA1 and linA2).…”

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.

“…These strains were found to contain lin genes highly similar to UT26 and B90A 14,[17][18][19] . Most of the lin genes in these organisms were also found to be associated with IS6100 element [17][18][19]22 . The fi nding of virtually identical lin genes and IS6100 in sphingomonads, isolated from different parts of the globe, is suggestive of recent horizontal gene transfer (HGT).…”

“…Furthermore, S. indicum B90A was reported to contain several copies of an insertion sequence, IS6100 (originally isolated from a Gram-positive bacterium, Mycobacterium fortuitum FCI) 16 , which were found to be associated with most of the lin genes in this strain 15 . Recently, several HCH-degrading sphingomonads have been isolated from the HCH contaminated soils from different geographical locations [17][18][19][20][21][22] . These strains were found to contain lin genes highly similar to UT26 and B90A 14,[17][18][19] .…”

“…Bioremediation has been proposed as an apt method for decontamination of HCH as chemical and physical methods are not only costly but also ineffective [70,71,72]. Since S. indicum B90A has now been reported to have better potential for HCH degradation, this strain can be used for this purpose.…”

The unusual process of production of hexachlorocyclohexane (HCH) and extensive use of technical HCH and lindane has created a very serious problem of HCH contamination. While the use of technical HCH and lindane has been banned all over the world, India still continues producing lindane. Bacteria, especially Sphingomonads have been isolated that can degrade HCH isomers. Among all the bacterial strains isolated so far, Sphingobium indicum B90A that was isolated form HCH treated rhizosphere soil appears to have a better potential for HCH degradation. This conclusion is based on studies on the organization of lin genes and degradation ability of B90A. This strain perhaps can be used for HCH decontamination through bioaugmentation.
