Abstract

A phenol-degrading bacterium strain PA was successfully isolated from the effluent of petrochemical wastewater. Based on its morphological, physiological and biochemical characteristics, the strain PA was characterized as a Gram-negative, strictly aerobic, nonmotile and short rod-shaped bacterium that utilizes phenol as a sole carbon and energy source. 16S rDNA sequence analysis revealed that this strain is affiliated to Acinetobacter calcoaceticus in the group of Gammaproteobacteria. The strain was efficient in removing 91.6% of the initial 800 mg ∙ L(-1) phenol within 48 h, and had a tolerance of phenol concentration as high as 1700 mg ∙ L(-1). These results indicated that A. calcoaceticus possesses a promising potential in treating phenolic wastewater.
