عزل وتشخيص بكتريا مكسرة للفينول من ترب محلية في محافظة بابل

Abstract

Eight bacterial isolated of phenol biodegrading were isolated from agricultural and oily polluted soils. These isolates were identified according to cultural features and biochemical tests. The results showed that five isolates were belonged to Bacillus subtilis while two isolates belonged to P. aernginosa from agricultural soils and one isolate form oily polluted soil. The ability of these isolate to tolerant phenol concentration from 10-100mg/L. All of these isolates were tolerant to these concentration but the concentration was studied 20mg/L was the most prefer concentration due to the absorbance on 600nm for 84hr old bacterial culture at 37co.
