Streptomyces Griseorubens is an Actinobacteria That Can Degrade Cypermethrin Insecticide

The insecticide cypermethrin is part of the synthetic pyrethroid family. This insecticide is dangerous for humans. It causes cerebral disorders and locomotion, a decrease in immunity has been observed in humans after acute intoxication. It is a possible carcinogen for humans according to the US Environmental Protection Agency (EPA). It is not soluble in water and can therefore accumulate in aquatic ecosystems. Its toxicity is also very high for aquatic organisms and may cause long-term adverse effects in aquatic environments. It is also toxic to bees. This pesticide has been used since 1970 all over the world. Biological treatment techniques are needed to overcome the devastating effects of this pollutant. The microorganisms present in the agricultural soil are the main actors of the suppression of these effects. In this study, we isolated an actinomycete strain capable of degrading the insecticide Cypermethrin at a concentration of 500 mg / L and at a temperature of 30 ° C for less than 21 days of incubation when provided as sole carbon source. Molecular identification by 16S rRNA showed homology with Streptomyces griseorubens. The biodegradation capacity of this strain reveals its significant potential in the bioremediation of cypermethrin-contaminated soil or aquatic ecosystems.
