Fig. 3From: Improving phloroglucinol tolerance and production in Escherichia coli by GroESL overexpressionTolerance assays for GroESL overexpression of E. coli BL21(DE3). a On LB agar plate. b Viable cell counts (CFU/mL). Strains were induced by 0.2 mM IPTG for 2 h, diluted and spread on LB agar plates under 0.7 g/L phloroglucinol and 0.1 mM IPTG, and then incubated at 30 °C for 20 hBack to article page
