Abstract

Abstract

This paper discusses the biodegradation of benzene in anaerobic microcosms. The incovula were from the suburban rice soil. The results indicate that benzene and toluene degradation occurred concomitantly with nitrate reduction in enrichment and transfer cultures. Toluene was degraded more readily than benzene, and benzene degradation was enhanced by the presence of toluene. This is an instance of benzene degradation on nitrate reducing conditions.
