Batch fermentation profile of optical density and various nutrients in glucose minimal and complex medium. (A) Profiles of optical density and residual concentrations of the glucose, acetate and lactate in glucose minimal medium, (B) optical density and residual concentrations of glucose, trehalose, lactate and acetate in complex medium, (C) concentrations of amino acids which were rapidly consumed in complex media and (D) amino acids which were not completely consumed. Highlighted regions correspond to exponential growth phases of the cultures and the corresponding nutrient consumption/secretion profiles were used for in silico simulations.
