Growth rate-dependent control of the rrnB P1 core promoter in Escherichia coli.

abstract：:Earlier observations that phenol is a repellent for Salmonella typhimurium but an attractant for Escherichia coli were confirmed. This behavioral difference was found to correlate with a difference in the effect phenol had on receptor methylation levels; it caused net demethylation in S. typhimurium but net methylatio...
