Promoter activities of Pcap5::blaZ transcriptional fusion in plasmid pAM3176 (A) and translational fusion in plasmid pAM3175 (B) in strains Newman and CYL6621 (Newman ΔsbcDC) were analyzed at 4, 8, and 24 h. The BlaZ activities are expressed as the ratio of A482 of the enzymatic reaction to the OD660 of the culture. The error bars indicate standard deviations of at least three independent experiments.
