Fig. 4From: Boosting isoprene production via heterologous expression of the Kudzu isoprene synthase gene (kIspS) into Bacillus spp. cell factoryInfluence of IPTG concentration on isoprene production of the different strains used in this study. The average concentrations (µg/L/OD600) were obtained from three independent cultures starting with the standard OD600 nm of 0.1.
