Degradation of Aroclor 1221 in soil by a hybrid pseudomonad.

abstract：:FNR is an iron-binding transcriptional regulator of Escherichia coli which controls the expression of target genes in response to anaerobiosis. The mechanism used by FNR to sense and respond to anaerobiosis is unknown but it is thought to involve iron. In vitro transcription analyses have shown that iron-deficient FNR...
