Figure 1From: Reduced catabolic protein expression in Clostridium butyricum DSM 10702 correlate with reduced 1,3-propanediol synthesis at high glycerol loadingGrowth curves, pH profiles, glycerol utilization, and end-product synthesis profiles of C. butyricum cultures with low (170Â mM) and high (620Â mM) initial glycerol concentrations. a) OD of cells in log scale versus pH values, b) residual glycerol concentrations versus 1,3-PDO concentrations, c) H2 and CO2 concentrations, d) lactate, acetate, butyrate and ethanol concentrations.Back to article page
