“…But it is very difficult to extrapolate the results obtained in the laboratory systems to predict their fate in the environment [Spain et al 1990]. The microbial degradation of HCH isomers in liquid cultures has been studied using pure microbial cultures such as Clostridium rectum, Pandoraea [Ohisa et al 1990, Okeke et al 2002, mixed native soil microbial population (undefined consortium) [Bachmann et al 1988a, Sahu et al 1995, Phanerochaete chrysosporium [Kennedy et al 1990, Mougin et al 1997 and sewage sludge under aerobic and anaerobic conditions [Bachmann et al 1988b, McTernan, and Pereira 1991, Buser, and. Mueller 1995.…”

“…A lot of information is available on the biodegradation of γ-HCH and other isomers of HCH using pure bacterial cultures, Pseudomonas aeruginosa, ITRC-5, Xanthomonas species, Clostridium rectum, Pandoraea spp etc [7][8][9][10]. Studies have also been carried out on the degradation of HCH isomers using sewage sludge under aerobic and anaerobic conditions [11][12][13]. It was observed that the isomers β-and δ-HCH were resistant to biodegradation under aerobic and anaerobic conditions, but α-and γ-HCH degraded upto 90%.…”

Hexachlorocyclohexane (HCH) isomers are reported to persist in the environment long after their usage is discontinued. Pleurotus florida, a white rot fungus, was found to degrade not only γ-HCH but also its more persistent isomers individually as well as a mixture in a Raper's complete medium. Within 30 days γ-HCH degraded completely, whereas other 3 isomers degraded 92-99%. The degradation rate was γ-HCH>β-HCH>α-and δ-HCH. The mycelium biomass was free from γ-HCH residues but accumulated about 3% residues of other 3 isomers. Presence of intermediate metabolites was not detected indicating complete mineralization of HCH isomers. Ability of P. florida to degrade HCH isomers was further studied in soil by amendment with spent mushroom substrate (SMS). SMS addition could marginally increase degradation of α-, β-and δ-HCH, but significantly increased degradation of γ-HCH. When the study was repeated similar trend was observed. The half-life of degradation of γ-HCH was 439-570 days in un-amended soil while 37-42 days in SMS amended soil. For other 3 stable isomers the half-life was reduced from 686-828 to 88-125 days by SMS amendments. These results indicate that SMS from P. florida cultivation can be utilized for bioremediation of HCH contaminated site.

“…But it is very difficult to extrapolate the results obtained in the laboratory systems to predict their fate in the environment [9]. The microbial degradation of HCH isomers in liquid cultures has been studied using pure microbial cultures such as Clostridium rectum, Pandoraea [10,11], mixed native soil microbial population (undefined consortium) [12,13], Phanerochaete chrysosporium [14,15] and sewage sludge under aerobic and anaerobic conditions [16][17][18]. The degradation of ␣ and ␥-isomers was almost complete and ␤ and ␦-isomers showed more resistance to degradation.…”
