Fig. 3From: Isoprene production by Escherichia coli through the exogenous mevalonate pathway with reduced formation of fermentation byproductsEffects of IPTG induction on isoprene production and cell growth of the MGpsPtpM strain (MG1655 harboring pTS-sPtispS and pS-NA). Culture was carried out in TB medium containing 2.0% (w/v) glycerol without IPTG (open squares) or with 0.1 mM IPTG (closed squares) for 36 h at 30 °CBack to article page
