Deltamethrin Pyrethroids
Deltamethrin is a synthetic pyrethroid, a diverse group of broad spectrum pesticides used widely around the world. Deltamethrin is highly persistent in the environment and it is extremely toxic to non-target organisms such as aquatic organisms and fishes (Imamura et al., 2004). The biodegradation of pyrethroids is slower in the environment than the naturally occurring pyrethrins. This persistence in the environment highlights the importance of finding ways to increase the rate of degradation of synthetic pyrethroids. Several bacteria have been found to be capable of degrading synthetic pyrethroids (Jilani and Khan, 2006). Microbial degradation is the most important way in which xenobiotics like pesticides are degraded in the environment (Grant
et al., 2004). Augmentation of the natural degradation of pesticides is important to clear persistent residues of synthetic pyrethroids from the environment. Hence, it is important to screen for bacterial species capable of biodegradation of deltamethrin and to develop a consortium of bacteria for use in in situ biodegradation in contaminated soils and aquatic environments. Keeping this in mind, an attempt was made to isolate deltamethrin-degrading bacteria and its efficiency of degrading deltamethrin was investigated.
