Malathion Biodegradation by Isolated Bacteria from Arvandkenar Contaminated Soil

Article excerpt

Background: Malathion is one of the organophosphorus insecticides which has a wide variety of applications in the agriculture industry. Its harmful toxic effects on animals range from invertebrates to vertebrates including human. Malathion can be degraded using physical, chemical or bio- logical methods. Bioremediation is effective when compared to the other methods and applicable for insitu bioremedia- tion. Present study reports the isolation, morphological and biochemical analysis of malathion degrading bacteria isolated from Arvandkenar contaminated soil.

Methods: Malathion degrading bacteria were isolated from Arvandkenar contaminated soil by serial dilutions of enriched consortium. In order to assess the utilization rates of Mala- thion using the isolated strains, microbial inoculums were passed to the mineral salt medium with malathion (2ml/l) as the sole carbon and energy source. The efficiency of isolated strains was assessed by monitoring the malathion biodegrada- tion (using GC- FID). …
