Reclamation of Phenol Contaminated Wastewater by Paenibacillus sp.

Abstract

Phenol and its compounds are toxic and hazardous material for environment even in low concentrations. So removal of these compounds from wastewaters is very important. There are many methods for removal of phenol from contaminated wastewaters among which biodegradation is more attractive. In this study presuming the availabity of phenol degrading-bacterium in phenolic wastewater, indigenous bacterium were isolated and identified by PCR. The growth curve and phenol removal of this bacterium were prepared. Results showed that the best isolated was the stain of Paenibacillus that can remove 1000 mg.l-1 phenol during 96 hours. The results showed that indigenous bacterium can remove high concentration of phenol from contaminated wastewater.
