Bacterial strains capable of degrading man‐made xenobiotic compounds are good
materials to study bacterial evolution towards new metabolic functions. Lindane (γ …

Background Sphingobium spp. are efficient degraders of a wide range of chlorinated and
aromatic hydrocarbons. In particular, strains which harbour the lin pathway genes mediating …

Chiral organic contaminants, like α-hexachlorocyclohexane (α-HCH), showed isotope
fractionation and enantiomer fractionation during biodegradation. This study aims to …

The widespread use of organochlorine pesticides (OCPs), mainly in the past, has caused
serious environmental problems. Many OCPs were recently categorized as persistent …

Contamination of soils and sediments with the highly persistent hexachlorocyclohexanes
(HCHs) continues to be a threat for humans and the environment. Despite the existence of …

Although the production and use of technical hexachlorocyclohexane (HCH) and lindane
(the purified insecticidal isomer γ‐HCH) are prohibited in most countries, residual …

Sphingopyxis inhabit diverse environmental niches, including marine, freshwater, oceans,
soil and anthropogenic sites. The genus includes 20 phylogenetically distinct, valid species …

Hexachlorocyclohexane (HCH), a synthetic organochloride, was first used as a broad-acre
insecticide in the 1940s, and many HCH-degrading bacterial strains have been isolated …

Two distinct microbial dehalogenases are involved in the first steps of degradation of
hexachlorocyclohexane (HCH) isomers. The enzymes, LinA and LinB, catalyze …

ABSTRACT δ-Hexachlorocyclohexane (δ-HCH), one of the prevalent isomers of technical
HCH, was enantioselectively dehydrochlorinated by the dehydrochlorinases LinA1 and …
