Screening of white rot fungal species for their capacity to degrade lindane and other isomers of hexachlorocyclohexane (HCH)

White-rot fungi have demonstrated a high capacity to degrade organic pollutants, including the insecticide lindane (y-HCH). The purpose of this study was to evalúate the degradative capacities of several white rot fungi species, Bjerkandera adusta, Irpex lacteus, Lentinus tigrinus, Phanerochaete chr...
