Residual substrate and products concentration during fermentation. Residual substrate, pellet protein, and pellet nitrogen concentrations (A); acetate, ethanol, formate and lactate concentrations (B); residual medium nitrogen and amino acid concentrations (C); amino acid nitrogen and total (supernatant and pellet) protein nitrogen concentrations (D); isobutanol, meso-2,3-butanediol, RR/SS-2,3,-butanediol, pyroglutamate, and xylitol concentrations (E); pyruvate, malate and fumarate concentrations (F). Figures B-F show the residual substrate concentration curve and an arrow indicating the time point at which cell growth stops in dark gray.
