Energetics ofSaccharomyces cerevisiae CBS 426: Comparison of anaerobic and aerobic glucose limitation

Publication Date May 1, 1981


Saccharomyces cerevisiae CBS 426 was grown aerobically and anaerobically in a glucose-limited chemostat. The flows of biomass, glucose, ethanol, carbon dioxide, oxygen, glycerol, and the elemental composition of the biomass were measured. Models for anaerobic and aerobic growth are constructed. Values for YATP and P/O are obtained from continuous culture data for aerobic growth; this YATP value is compared with that obtained from the anaerobic growth results. The ratio between the heat produced and the oxygen consumed increases if more glucose in fermented to ethanol and carbon dioxide. An equation for ϕH/ϕO as a function of the respiratory quotient is given.
