Many studies have showed that the pesticide residues in the environment increase day by day because of their continuous use. Pesticides can degrade chemically, physically and biologically. Biodegradation is an eco-friendly, inexpensive and highly effective approach compared to other methods. Bacteria are the most commonly used biological agents in biodegradation studies. Widespread use of pyrethroid pesticides such as deltamethrin causes pollution of environment. A total of 14 bacterial isolates were isolated from insects (Poecilimon tauricola, Locusta migratoria, Gryllus bimaculatus and Forficula auricularia) living in pesticide contaminated environments. These bacterial isolates were identified and characterized as Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Bacillus atrophaeus, Acinetobacter lwoffii, Rhodococcus coprophilus, Brevundimonas vesicularis, Pseudomonas syringae, Yersinia frederiksenii, Bacillus licheniformis, Enterobacter intermedius and Serratia marcescens based on biochemical and morphological properties and fatty acid profiles. As a result, these bacterial isolates can be used for the remove of deltamethrin at various environments.
