Fig. 4From: Improving phloroglucinol tolerance and production in Escherichia coli by GroESL overexpressionPhloroglucinol production of different recombinant strains in shake flask. Gray bars represent phloroglucinol concentration in the culture broth (g/L); dark bars represent cell density (OD600). Data were acquired after each strain was induced with 0.2 mM IPTG at 30 °C for 12 h. Error bars indicate standard deviations (n = 3)Back to article page
