Pyruvate supplementation increases total biomass yield and results in lactate production under aerobic conditions. Comparison of model predicted aerobic batch profiles (dashed line) to measured profiles in fermentation batches (N = 2, dots and pyramids) after pyruvate supplementation to medium for: (A) biomass, dotted grey lines indicate variation in the final concentration of biomass reached, (B) glucose, (C) pyruvate, (D) lactate, (E) acetate concentration, and (F) energy distribution early stage (top) and at t = 45h.
