| Abstract | ||||
| A new indigenous soil phenol-degrading bacterium strain S2 was successfully isolated from Oum ghellaz lake shore soil in Oran in Algeria. Based on its morphological, physiological and biochemical characteristics, the strain S2 was characterized as a Gram-positive, facultatively anaerobic, forms endospores, and short rod-shaped bacterium that utilizes phenol as a sole carbon and energy source also other phenolic compounds. 16SrDNA sequence analysis revealed that this strain is belongs to Niallia nealsonii in the group of firmicutes. The strain was efficient in removing 91.6% of the initial 500 mg.L-1phenol within 48 h and had a tolerance of phenol concentration as high as 1500 mg.L-1. These results indicated that Niallia nealsonii has promising bioremediation potential. | ||||
