The tolerance of some pesticides by two anoxygenic phototrophic bacteria, isolated from leather industry effluents, was investigated. Rhodobacterium capsulatus was found to be more resistant than Rhodopseudomonas acidophila to the pesticides tried in the present investigation. The pattern of inhibition of growth for both the organisms show that chlorpyrifos was most potent followed by methyl parathion, endosulfan, rogor and kitazin in a descending order.

Abstract


The tolerance of some pesticides by two anoxygenic phototrophic bacteria, isolated from leather industry effluents, was investigated. Rhodobacterium capsulatus was found to be more resistant than Rhodopseudomonas acidophila to the pesticides tried in the present investigation. The pattern of inhibition of growth for both the organisms show that chlorpyrifos was most potent followed by methyl parathion, endosulfan, rogor and kitazin in a descending order.
