ISOLATION AND CHARACTERIZATION OF PHENOL DEGRADING BACTERIA FROM INDUSTRIAL WASTEWATER AND SEWAGE WATER

This study examines the isolation and characterization of phenol-degrading-bacteria, Five isolates named C2, P4, M4, O3, S3, from effluent ceramic factories (C2), petrochemical (P4), pulp paper mill (M4), crude oil (O3) sewage water (S3) have been investigated. These were characterized depending on their morphological, biochemical characteristics, only one isolate was as a Gram-positive, strictly aerobic, nonmotile, cocci-shaped bacterium might be Micrococcus sp. two (Pseudomonas sp.: (P4&S3) recogniced Gram-negative, motile short rod-shaped isolates(Bacillus (C2& O3) idenihied long rod- shape bacterium. The five bacterial able to utilize phenol sole carbon source. checked for growth minimal salt medium amended with different concentrations phenol. tolerant grow at higher they investigated ability degrade Among degrading isolates, can tolerate up 1500 ppm .of concentrations, 90% within 72 hrs. optimum temperature pH 35 0C 7, respectively. yeast extract ammonium chloride is best nitrogen source degradation phenol, P4 efficient in removing about initial 1000 48 hrs., had tolerance concentration high ppm. results indicated that presumptive Pseudomonas spp. possesses promising potential treating phenolic wastewater
