The Hexachlorocyclohexane (HCH) isomers are highly toxic and persistent organochlorine pesticides, which have caused serious environmental problems since they began to be produced at the beginning of the 1940s. During the synthesis of lindane (gamma-HCH), other isomers were also synthesized. There are seven isomers, but only gamma-HCH possesses insecticidal activity. However, the other isomers are still toxic for humans and in the environment they cause an accumulation of the more persistent form, the β-HCH. For this reason we have focused on the ability of biotransformation of HCH isomers by Gram-positive microorganisms and particularly by actinobacteria species.
