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.
摘要
受芳香族化合物污染的地下环境可以通过 Geobacter 物种进行原位修复。在 Geobacter bemidjiensis 以乙酸盐为生长基质时，鉴定到一种转录因子，它可以抑制 BamA 的表达，BamA 是一种受苯甲酸诱导的基因。该抑制剂很可能也调控了其它参与芳香族化合物代谢的基因。
