## Abstract The influence of temperature (15° −40°C) and pH (2.5–6.0) on the continuous growth of bakers' yeast (__Saccharomyces cerevisiae__) at steady state in 1% ethanol was investigated. Optimal temperature and pH were 30°C and 4.5, respectively. The short‐term effect of ethanol concentration (
With glucose as carbon source, as reported by other authors (Conway et al., 1950), yeast cells accumulated large amounts of CO 2 , carbonic acid, bicarbonate and K + than when grown with ethanol. The addition of propionic acid to the cells produced an increase in the potassium ion accumulation when
