Elucidating the transition between submerged culture and solid-state bakers' yeast fermentations

A semisolid gelatin medium is developed to elucidate, by kinetic analysis, the transition between submerged and solid-state yeast fermentations. Using gelatin, rather than the more usual starch medium to develop the solid state, permits the cells to be separated from the solid medium by use of low temperature melting. Thus, meaningful kinetic data can now be collected. Time trajectories of cell mass, pH, ethanol, acetaldehyde, glycerol, and intracellular free lysine concentrations are established for batch fermentations.
