Abstract
Biodegradation of endosulfan isomers in soil-applied and flask-coated condi tions was studied, by an isolated bacterial coculture. The degradation in s oil-applied form was 20-30% slower than in flask-coated condition. Addition of a biosurfactant, isolated from Bacillus subtilis MTCC 1427, enhanced th e rate of biodegradation by 30-45% in both the conditions. It also mobilize d the residual endosulfan towards biodegradation, that otherwise remains un degraded.
