“…As early as 1974, Melnikov [19] summarized the lindane residue data from soils of USA, England and Japan and found residues to vary from 0.04 to 0.26 mg/kg. Similar reports were then documented from other developed countries, such as the Netherlands [20,21], Sweden [22] and Japan [23]. Residues of HCH were also detected in soils in various parts of India, ranging from 0.125 ppm to 0.5 ppm [24,25].…”

Hexachlorocyclohexane (HCH) is an organochlorine insecticide which has been banned in technologically advanced countries. However, it is still in use in tropical countries for mosquito control and thus new areas continue to be contaminated. Anaerobic degradation of HCH isomers have been well documented but until recently there have been only a few reports on aerobic microbial degradation of HCH isomers. The isolation of these microbes made it possible to design experiments for the cloning of the catabolic genes responsible for degradation. We review the microbial degradation of HCH isomers coupled with the genetic manipulations of the catabolic genes. The first part discusses the persistence of residues in the environment and microbial degradation while the second part gives an account of the genetic manipulations of catabolic genes involved in the degradation.

“…DDT has been detected at significant concentrations in the tissue of a number of animals ( Hunnego and Harrison 1971; Gilbert et al . 1990 ), and the organochlorine has also been reported to accumulate in grain, cotton and natural vegetation ( Voerman and Besemer 1975; Smelt et al . 1975 ).…”

Microbial analysis of contaminated soil and uncontaminated plant and faecal material resulted in the enrichment of a number of microbial communities capable of utilizing a range of environmental pollutants. Growth was observed on polycyclic aromatic hydrocarbons, polychlorinated biphenyls, heterocyclic aromatic compounds and organochlorine pesticides. However, none of the communities could grow on pentachlorophenol. Pure cultures were isolated from microbial communities using phenanthrene and pyrene as the sole carbon and energy source. Isolates were also obtained using DDT, DOH, DBH and PCPA when peptone was supplemented to the medium. Strain AJR39,504, isolated using DDT and peptone, could not be positively identified on the basis of substrate utilization tests. However, it most closely resembled Stenotrophomonas maltophilia (0·424 similarity) using the Microlog 3 database software. Isolate AJR39,504 could also grow on polycyclic aromatic hydrocarbons, chlorinated‐ and nitro‐aromatic compounds. In addition, the degradation of DDT (100 mg l−1) by isolate AJR39,504 resulted in a 35% decrease in DDT concentration after 28 days with a concomitant increase in DDD concentration.
