From: Effect of Tween 40 and DtsR1 on l-arginine overproduction in Corynebacterium crenatum
Effect of Tween 40 addition (0–8 mg/mL Tween 40, after 36 h incubation time) and addition time (0–48 h, 5 mg/mL Tween 40) on l-Arg production in CCM01 strain. l-Arg production and the DCW were monitored during shake flask cultivation for 120 h by Tween 40 addition. Results are the means ± standard deviations from three independent experiments. Compared with the control group, “ns” designates P > 0.05, *P < 0.05; **P < 0.01; ***P < 0.001.
