Comparison of GDH enzyme activities of the strains E. coli BL21(DE3)pLysS(DE3), E. coli BL21(DE3)pLysS/dhaD (DE3/dhaD) and K. pneumoniae SRP2 (SRP2): a effect of incubation time on GDH activity after addition of 0.5 mM IPTG; b effect of incubation time on biomass production after addition of 0.5 mM IPTG; c effect of incubation temperature and IPTG concentrations on GDH activity after 3 h of IPTG induction; d effect of medium initial pH on GDH activity after 3 h of 0.5 mM IPTG induction
