Fig. 2From: The pyruvate decarboxylase activity of IpdC is a limitation for isobutanol production by Klebsiella pneumoniaeThe cell growth and metabolite production of K. pneumoniae ΔbudA–ΔldhA–ipdC and K. pneumoniae ΔbudA–ΔldhA–kivD in batch culture with IPTG induction. Cells were cultured in 5 L bioreactors and 1 mM of IPTG was added to the culture broth after 8 h of cultivation.
