Analysis of microbial community during anaerobic biodegradation of benzene and toluene using nitrate, sulfate, and Fe(Ⅲ) as alternative electron acceptors
Anaerobic degradation of aromatic compounds plays a major role in bioremediation processes, and there has been increasing information available on the anaerobic oxidation of aromatic compounds recently.1) Utilizing alternate electron acceptors during anaerobic degradation are increasingly considered for bioremediation of hydrocarbon-contaminated sites.2) In this study, we examined the anaerobic biodegradation of benzene and toluene by soil bacteria with nitrate, sulfate, or iron as electron acceptors. Biodegradation of benzene and toluene was more successful under existence of electron acceptor. And nitrate provided the highest efficiency for degradation of individual contaminant, followed by iron and sulfate. We performed DGGE which was for analysis of microbial community degrading benzene and toluene depending on the several different electron acceptor. The DGGE patterns showed that there were very different and diverse microorganisms. We were known that microorganisms were organized mainly by proteobacteria.
