Degradation of Endosulfan by Mixed Bacterial Cultures Enriched from Endosulfan Contaminated Soils of Southern India

Optimization of Endosulfan Degradation by Pseudomonas Aeruginosa

A total of 68 isolates capable of degrading Endosulfan were obtained out of 27 samples collected. Among them 28 isolates showed better efficiencies in degrading Endosulfan as compared to others. Isolate ENS10 which showed 42% degradation of Endosulfan under unoptimized condition was identified as Pseudomonas aeruginosa. After optimization process it was able to show 100% degradation of chlorpyr...

Enrichment of an endosulfan-degrading mixed bacterial culture.

An endosulfan-degrading mixed bacterial culture was enriched from soil with a history of endosulfan exposure. Enrichment was obtained by using the insecticide as the sole source of sulfur. Chemical hydrolysis was minimized by using strongly buffered culture medium (pH 6.6), and the detergent Tween 80 was included to emulsify the insecticide, thereby increasing the amount of endosulfan in contac...

The anaerobic degradation of endosulfan by indigenous microorganisms from low-oxygen soils and sediments.

Indigenous mixed populations of anaerobic microorganisms from an irrigation tailwater drain and submerged agricultural chemical waste pit readily biodegraded the major isomer of endosulfan (endosulfan I). Endosulfan I was biodegraded to endosulfan diol, a low toxicity degradation product, in the presence of organic carbon sources under anaerobic, methanogenic conditions. While there was extensi...

Degradation of Endosulfan in Different Soils by Indigenous and Adapted Microorganisms

Stereoselective degradation of aqueous endosulfan in modular estuarine mesocosms: formation of endosulfan gamma-hydroxycarboxylate.

Solutions of alpha-endosulfan, beta-endosulfan, and technical grade endosulfan (70alpha:30beta) were added to modular estuarine mesocosms; the kinetics and degradation products from each mesocosm are reported. The persistent product endosulfan sulfate was generated in all cases; however, its yield was approximately a factor of three higher from alpha-endosulfan relative to beta-endosulfan. Beta...
