通过一种分离的细菌共培养物，研究了硫丹异构体在土壤施用和烧瓶涂层条件下的生物降解。土壤施用形式的降解比烧瓶包衣条件下慢20 - 30%。添加一种从枯草芽孢杆菌MTCC 1427中分离的生物表面活性剂，在两种条件下均使生物降解率提高了30 - 45%。它还促使残留的硫丹进行生物降解，否则这些硫丹将无法降解。
Biodegradation of endosulfan isomers in soil-applied and flask-coated conditions was studied, by an isolated bacterial coculture. The degradation in soil-applied form was 20-30% slower than in flask-coated condition. Addition of a biosurfactant, isolated from Bacillus subtilis MTCC 1427, enhanced the rate of biodegradation by 30-45% in both the conditions. It also mobilized the residual endosulfan towards biodegradation, that otherwise remains undegraded.
