Identification of a transcriptional repressor involved in benzoate metabolism in Geobacter bemidjiensis

Abstract

Subsurface environments contaminated with aromatic compounds can be remediated in situ by Geobacter species. A transcription factor that represses expression of bamA, a benzoate-inducible gene, in Geobacter bemidjiensis during growth with acetate was identified. It is likely that this repressor also regulates other genes involved in aromatic compound metabolism. © 2011, American Society for Microbiology.
