Notes:
Growth of Saccharomyces cerevisiae LBG H 1022 on ethanol under steady-state conditions was studied. As a cultivation device, an aerated Chemap fermentor combined with continuously working gas analyzers for oxygen and carbon dioxide was used. Dry matter, substrate concentration, yield, specific oxygen uptake, specific carbon dioxide release, and respiration quotient, as well as nitrogen, carbon, phosphorus, hydrogen, and protein content of the cells were measured in dependence on the dilution rate. Cell size distribution, as a function of the specific growth rate, was determined with the aid of a Celloscope 202. A fair agreement with the theory of continuous culture for all metabolic curves could be established. An increased turnover rate resulted from the addition of glutamic acid to the synthetic growth medium. The primary effect of this supplement could be a rise in the flow rate of the tricarboxylic acid cycle.
