Fig. 6From: The pyruvate decarboxylase activity of IpdC is a limitation for isobutanol production by Klebsiella pneumoniaeThe cell growth and metabolites production of K. pneumoniae IpdC, K. pneumoniae T290L, K. pneumoniae L546W, and K. pneumoniae KivD in batch cultures 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.
