Bioremediation of Chlorpyrifos Using Bacteria Isolated from Pesticide Contaminated Soil
Keywords:
Chlorpyrifos, toxicity, bacteria, degradation and clean up technologyAbstract
Chlorpyrifos, used as an agricultural pesticide is a cause of great environment pollution and toxicity. Hence exploration of various chlorpyrifos degrading organisms to clean up the pollutant is of immense importance. Present study shows the great efficiency of bacteria in degradation of chlorpyrifos from minimal media where chlorpyrifos is the sole carbon source available for their growth. Four bacterial species isolated from chlorpyrifos contaminated soil showed growth in simulated conditions. These bacterial species were further checked for the extent of degradation. All the four showed degradation above 70%. The most efficient one Achromobacter spp. was further studied in detail for degradation along with parallel study of bacteria Pseudomonas aeruginosa previously known for degradation capability. Both these species showed degradation above 80%. Selected bacterial species showed promising result in degradation which can be harnessed in clean up technology for chlorpyrifos contaminated environment.
