Role of Rhizobacteria of Tea Garden in Bioremediation of Pesticide Residues in Tea Soil
Pratibha Huidrom [2] | GD Sharma
Abstract: Endosulfan is a neurotoxin organochlorine insecticide of the cyclodiene family of pesticides. It is an endocrine disruptor, and it is highly acutely toxic. It is a mixture of steroisomers, designated "?" and "?," in a 7:3 ratio. A rhizobacterium capable of metabolizing endosulfan was isolated from one of the tea gardens of South Assam, Silchar, India. Isolate AULS-B3 (Burkholderia sp.AULS-B3) was treated with increasing doses of endosulfan (2.5, 5.0, 10.0, 15.0 and 20.0 ?l/ml). After 48 hrs of incubation the sample was analyzed by HPLC, Perkin Elmer Series 200. The results indicated breakdown of endosulfan into other metabolites. Tea seedlings in pots were treated with an increasing dose of endosulfan coupled with Burkholderia sp AULS-B3 and Bacillus sp AULS-BAC to study growth parameters like shoot height, leaf number and root shoot ratio. The present work may provide a basis to study rhizobacteria of tea field soils that may not only degrade pesticides but also promote tea growth and help in establishing a clean and green environment.
