Figure 2From: Recombinant bromelain production in Escherichia coli: process optimization in shake flask culture by response surface methodologyEffects of different post-induction temperatures on bromelain activity by BL21-AI. Experiments were conducted at various post-induction temperatures (20-37°C), with OD600 nm of 0.4, 0.2% (w/v) L-arabinose and 4 hr post-induction period being constant.Back to article page
