Abstract
Flocculation is a dynamic process which has special advantages such as safety strong effect biodegradability and harmless to humans and the environment. The aim of this study is to screen bacterial isolates with the ability of producing biopolymer exopolysaccharides EPS to form floc. Twenty four bacterial isolates obtained from waste water contaminated with oil were screened for floc formation ability hydrophobicity biodegradation of crude oil ability and EPS production. The results showed only four bacterial isolates namely 6G 7G A16 and A60 were able to produce high percentage of floc formation; 31.9 0.26 25 and 23.7 respectively. The hydrophobicity of the cells expressed as ability of adherence to crude oil ranged from 96.5 to 91.7. All the isolates were able to produce high amount of EPS ranging from 4300 mg/L to 7700 mg/L. Isolate A16 showed the highest degradation of crude oil at 78.3 whereas isolate 68 and 78 only at 57.3 and 55.5 respectively.
