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

Degradation of Endosulfan in Different Soils by Indigenous and Adapted Microorganisms

Bioremediation of endosulfan contaminated soil and water -- optimization of operating conditions in laboratory scale reactors.

A mixed bacterial culture consisted of Staphylococcus sp., Bacillus circulans-I and -II has been enriched from contaminated soil collected from the vicinity of an endosulfan processing industry. The degradation of endosulfan by mixed bacterial culture was studied in aerobic and facultative anaerobic conditions via batch experiments with an initial endosulfan concentration of 50mg/L. After 3 wee...

Naturally occurring bacteria similar to the methyl tert-butyl ether (MTBE)-degrading strain PM1 are present in MTBE-contaminated groundwater.

Methyl tert-butyl ether (MTBE) is a widespread groundwater contaminant that does not respond well to conventional treatment technologies. Growing evidence indicates that microbial communities indigenous to groundwater can degrade MTBE under aerobic and anaerobic conditions. Although pure cultures of microorganisms able to degrade or cometabolize MTBE have been reported, to date the specific org...

Cellulose degradation in anaerobic environments.

In anaerobic environments rich in decaying plant material, the decomposition of cellulose is brought about by complex communities of interacting microorganisms. Because the substrate, cellulose, is insoluble, bacterial and fungal degradation occurs exocellularly, either in association with the outer cell envelope layer or extracellularly. Products of cellulose hydrolysis are available as carbon...

Enrichment and isolation of a mixed bacterial culture for complete mineralization of endosulfan.

In the present study, we isolated three novel bacterial species, namely, Staphylococcus sp., Bacillus circulans-I, and Bacillus circulans-II, from contaminated soil collected from the premises of a pesticide manufacturing industry. Batch experiments were conducted using both mixed and pure cultures to assess their potential for the degradation of aqueous endosulfan in aerobic and facultative an...
