Influence of pH and temperature on the substrate yield coefficient of yeast growth in a chemostat

The influence of pH and temperature on the substrate yield coefficient for growth of Saccharomyces cerevisiae in a chemostat under limited organic substrate conditions was studied. Mathematical analysis of the substrate yield coefficient as a function of pH and temperature in the near‐optimal area was made. It was shown that the location of pH and temperature optima were independent of each other. The maximum substrate yield coefficient had the following coordinates: pH = 4.1, temperature = 28.5°C.
