Isolation and Identification of some Phenol Degrading Bacterial Species from some Contaminated Environments

Abstract

Abstract Phenol and its derivatives are toxic substances that harm a variety of living organisms, including plants, animals, and aquatic life. Therefore, in order to save the environment, these substances must be effectively removed. The purpose of this study is to screen and select potent phenol degrading strains from oil contaminated soils as well as testing their capacity to break down phenols. After growing on the phenol-containing mineral salts medium (MM), the chosen strains were identified using biochemical testing by Vitek 2 compact system in addition to morphological identification. After 168 hours of incubation, the chosen strains were identified as Aeromonas salmonicida, Escherichia hermannii, Acinetobacter lwoffii, Enterobacter cloacae complex, Sphingomonas paucimobilis,, and Pantoea spp. All of the selected strains were grown efficiently at a concentration of 100mg/ml, so they may be putative species for bioremediation of phenol contaminated environments.
