Diauxic growth of Clostridium acetobutylicum ATCC 824 when grown on mixtures of glucose and cellobiose

Kinetics of growth and metabolism of glucose or cellobiose as the substrate by C. acetobutylicum. a Glucose as the substrate (136 mM) and glucose-pregrown cells as the inoculum. b Cellobiose as the substrate (67 mM) and glucose-pregrown cells as the inoculum. The dashed line represents le beginning of the lag phase after glucose was exhausted. (c) Cellobiose as the substrate (67 mM) and cellobiose-pregrown cells as the inoculum. d–f are the respective product kinetics of (a–c). Each graph is representative of at least three independent experiments (n？=？3
