Five actinomycete strains isolated from pesticide-contaminated sediments were able to grow in the presence of 10 mg l1 lindane, an organochlorine pesticide. The strain growing best in the presence of lindane as the only carbon source was identi.ed as Streptomyces sp. M7. After 96 h of incubation in synthetic medium containing lindane and glucose, both substrates were simultaneously consumed; glucose 6.0 g l1 improved lindane degradation and obtained biomass. When Streptomyces sp. M7 was cultured in presence of lindane plus glucose, the disappearance of the pesticide from the medium and the lindane degradation was observed after 72 h of incubation. This is the .rst report of lindane degradation without intracellular accumulation or biotransformation products of lindane using Streptomycesmg l1 lindane, an organochlorine pesticide.
