Biodegradation of pesticide complex chlorpyrifos + cypermethrin by microorganisms isolated from the Southern Aral Sea region

Abstract

Microbiological study of soil samples with low pesticide content was conducted. Seven pure cultures were isolated: four related to Bacillus and three to Pseudomonas genera. Conducted study analyzing growth and biochemical activity of natural cultures on synthetic media revealed ability of two cultures (Bacillus sp. 2 -30 and Bacillus sp. 1 -17) to degrade complex of pesticides chlorpyrifos+cypermethrin.
