Lindane uptake and degradation by aquatic Streptomyces sp. strain M7
Five actinomycete strains isolated from pesticide-contaminated sediments were able to grow in the presence of 10 μg l −1 lindane, an organochlorine pesticide. The strain growing best in the presence of lindane as the only carbon source was identified as Streptomyces sp. M7. After 96 h of incubation...

Summary: | Five actinomycete strains isolated from pesticide-contaminated sediments were able to grow in the presence of 10
μg
l
−1 lindane, an organochlorine pesticide. The strain growing best in the presence of lindane as the only carbon source was identified 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
l
−1 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 first report of lindane degradation without intracellular accumulation or biotransformation products of lindane using
Streptomyces sp. under aerobic conditions.
This is the first report of lindane removal without intracellular accumulation or biotransformation products of lindane using
Streptomyces sp. strain M7, an actinomycete isolated from pesticide-contaminated sediments from Tucuman, Argentina. |
