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...
متن کاملEnrichment and isolation of endosulfan-degrading microorganisms.
Endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,3,4-benzo-dioxathiepin-3-oxide) is a cyclodiene organochlorine currently used as an insecticide all over the world and its residues are posing a serious environmental threat. This study reports the isolation and identification of enriched microorganisms, capable of degrading endosulfan. Enrichment was achieved by using t...
متن کاملEnrichment 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...
متن کاملEnrichment And Isolation Of Endosulfan Degrading Microorganisms In Cashew Plantations Of Kasargod District, Kerala
Organochlorine pesticides are one of the major groups of chemicals responsible for environmental contamination. Endosulfan a pesticide used mainly in cashew plantation is a highly toxic endocrine disrupter and a contact stomach poison. To study the endosulfan degrading microorganisms, 20 soil samples were collected from five different cashew plantations having a history of endosulfan applicatio...
متن کاملRubber-degrading enzyme from a bacterial culture.
Rubber-degrading activity was found in the extracellular culture medium of Xanthomonas sp. strain 35Y which was grown on natural rubber latex. Natural rubber in the latex state was degraded by the crude enzyme, and two fractions were separately observed by gel permeation chromatography of the reaction products. One fraction was of higher molecular weight (HMW) with a very wide MW distribution f...
