Volume : III, Issue : V, June - 2013 MICROBIAL DEGRADATION OF MONOCROTOPHOS BY PSEUDOMONAS STUTZERI K.BARATHIDASAN AND D.REETHA Published By : Laxmi Book Publication Abstract : Monocrotophos (MCP), an organophosphorus insecticide, is widely used to
control insects on crops. Being readily water soluble and highly toxic, its removal from
contaminated soil and water becomes inevitable. For the evaluation of
biomineralization of monocrotophos, a bacterial strain, Pseudomonas stutzeri MTCC
2300 which is capable of degrading monocrotophos, was obtained from MTCC. The
ability of the strain to mineralize monocrotophos was investigated under different
culture conditions. The strain was able to degrade MCP to the extent of 96%, from the
medium containing MCP at the concentration of 500mg/l-1, within 6 days at 30°C. The
culture degrades MCP to carbon dioxide, ammonia and phosphates were determined. In
the present study, the results revealed that, the microbial strain, Pseudomonas stutzeri
MTCC 2300 could be used for the bioremediation of waste water and pesticide
contaminated soil. Keywords : Article : Cite This Article : K.BARATHIDASAN AND D.REETHA, (2013). MICROBIAL DEGRADATION OF MONOCROTOPHOS BY PSEUDOMONAS STUTZERI.
