Tk. Vandyk et al., SYNERGISTIC INDUCTION OF THE HEAT-SHOCK RESPONSE IN ESCHERICHIA-COLI BY SIMULTANEOUS TREATMENT WITH CHEMICAL INDUCERS, Journal of bacteriology, 177(20), 1995, pp. 6001-6004
Escherichia coli strains carrying transcriptional fusions of four sigm
a(32)-controlled E. coli heat shock promoters to luxCDABE or lacZ repo
rter genes were stressed by chemicals added singly or in pairs. Much m
ore than additive induction resulted from combinations of cadmium chlo
ride, copper sulfate, ethanol, formamide, 4-nitrophenol, and pentachlo
rophenol.
