Abstract

In the present study an attempt has been made to enrich and isolate bacterial species capable of degrading endosulfan isomers from different soil habitats. The two potent isolates showed about 51% endosulfan degradation during first eight days of incubation. However, the degradation reached between 63-82% after 16 days of incubation. Further, the degradation of the insecticide increased concomitantly with the growth of the bacteria at pH 8.0 and at 30°C. The results suggest that these novel strains could be used as potent agents for biodegradation of endosulfan pesticides.

Abstract

The concept of sustainable agriculture serves a broad range of needs at the local level and is highly important for the quality of life. Agriculture systems purposefully disrupt natural systems, in an ecological sense, through patterns of human intervention. The increased consumption pattern of chemical fertilizers and chemical pesticides has led to changes in physicochemical and biological properties of soil. The chemical farming system has led to considerable loss of soil organic matter showing 0.66% when compared to natural farm soil, which shows 2.7% of organic matter. 86 mg/kg of heavy metals like chromium was detected in chemical farming, which is detrimental to the growth and development of plants.
