Fig. 3From: Improvement of free fatty acid production using a mutant acyl-CoA thioesterase I with high specific activity in Escherichia coli Free fatty acid production of selected strains from the ‘TesA mutant library. The expression of ‘TesA was induced with 0.3 mM IPTG, and the cells were cultivated for 48 h post-induction. Parenthesises indicate mutation of the ‘TesA. Filled circles indicate the optical density of each culture after 48 h. Error bars mean standard deviations of three independent experimentsBack to article page
