The cell biomass and enzyme activity of pET32a-SyCA in different engineered E. coli strains. a The relative biomass of different strains harboring pET32a-SyCA with or without 0.1 mM IPTG induction. (+) meant with IPTG and (−) meant without IPTG. Each strain without induction was chosen as standard, respectively. b The activity of crude enzyme of pET32a-SyCA with 0.005, 0.01, 0.1 mM IPTG in different strains determined by Wilbur–Anderson assay
