Figure 3From: Recombinant bromelain production in Escherichia coli: process optimization in shake flask culture by response surface methodologyEffects of different inducer concentrations on bromelain activity by BL21-AI. Tests were carried out at varying L-arabinose concentrations (0.1-0.3% w/v) while OD600 nm of 0.4, 37°C and 4 hr post-induction period were kept constant.Back to article page
