Figure 4From: Metabolic engineering of Escherichia colifor the biosynthesis of alpha-pineneEffect of inducer concentration on α-pinene production by YJM28. When OD600 reached 0.6-0.9, cultures were induced at 30°C for 66 h using different concentrations of IPTG: 0.1 mM (■), 0.25 mM (♦), 0.5 mM (▲), 1 mM (●) The experiment was conducted in triplicate.Back to article page
