Fig. 1From: A two-stage temperature control strategy enhances extracellular secretion of recombinant α-cyclodextrin glucosyltransferase in Escherichia coli Effect of second-stage temperature on extracellular α-CGTase production. After α-CGTase expression was induced at 25 °C for 24 h, the temperature was shifted directly to 30 °C (▲), 34 °C (♦), or 37 °C (■). The temperature of the control culture (●) was maintained at 25 °CBack to article page
