Biochemistry of microbial degradation of hexachlorocyclohexane and prospects for bioremediation.

• R. N. Lal, Gunjan Pandey, +8 authors John G Oakeshott
• Microbiology and molecular biology reviews : MMBR
• 2010

Lindane, the gamma-isomer of hexachlorocyclohexane (HCH), is a potent insecticide. Purified lindane or unpurified mixtures of this and alpha-, beta-, and delta-isomers of HCH were widely used as… (More)

Organization of lin genes and IS6100 among different strains of hexachlorocyclohexane-degrading Sphingomonas paucimobilis: evidence for horizontal gene transfer.

• Charu Dogra, Vishakha Raina, +6 authors R. N. Lal
• Journal of bacteriology
• 2004

The organization of lin genes and IS6100 was studied in three strains of Sphingomonas paucimobilis (B90A, Sp+, and UT26) which degraded hexachlorocyclohexane (HCH) isomers but which had been isolated… (More)

Hexachlorocyclohexane-degrading bacterial strains Sphingomonas paucimobilis B90A, UT26 and Sp+, having similar lin genes, represent three distinct species, Sphingobium indicum sp. nov., Sphingobium…

A microscopically pure enrichment culture of a gram-negative anaerobic bacterium, in the present article referred to as PER-K23, was isolated from an anaerobic packed-bed column in which… (More)

Proposal of biostimulation for hexachlorocyclohexane (HCH)-decontamination and characterization of culturable bacterial community from high-dose point HCH-contaminated soils.

• Mandeep Dadhwal, Amandeep Singh, +7 authors R. N. Lal
• Journal of applied microbiology
• 2009

AIMS To locate a high-dose point hexachlorocyclohexane (HCH)-contaminated site, to identify HCH-degrading bacteria in it and assay HCH-decontamination by biostimulation. METHODS AND RESULTS… (More)

Cloning and characterization of lin genes responsible for the degradation of Hexachlorocyclohexane isomers by Sphingomonas paucimobilis strain B90.

• Rekha Kumari, Sanjukta Subudhi, +7 authors Rup Lal
• Applied and environmental microbiology
• 2002

Hexachlorocyclohexane (HCH) has been used extensively against agricultural pests and in public health programs for the control of mosquitoes. Commercial formulations of HCH consist of a mixture of… (More)

The proton/electron ration of the menaquinone-dependent electron transport from dihydrogen to tetrachloroethene in "Dehalobacter restrictus".

• Wolfram Schumacher, Christof Holliger
• Journal of bacteriology
• 1996

In the anaerobic respiration chain of "Dehalobacter restrictus," dihydrogen functioned as the electron donor and tetrachloroethene (PCE) functioned as the electron acceptor. The hydrogenase faced the… (More)

Microbial communities in a porphyry copper tailings impoundment and their impact on the geochemical dynamics of the mine waste.

• Nouhou Diaby, Bernhard Dold, H E Pfeifer, Christof Holliger, David Barrie Johnson, Kevin B. Hallberg
• Environmental microbiology
• 2007

The distribution and diversity of acidophilic bacteria of a tailings impoundment at the La Andina copper mine, Chile, was examined. The tailings have low sulfide (1.7% pyrite equivalent) and… (More)
