Long term influence of a submaximal temperature (39.5 °C) on a continuous culture of Saccharomyces cerevisiae in a pH‐stat resulted in a reduction of its growth rate from 0.3 h −1 to 0.04 h −1 . In consequence of an altered anabolism of the yeast cells a strong and irreversible decrease of the contents of intracellular polymers (DNA, RNA and protein) was stated. Additional changes in the energy metabolism, e.g. , the activation of anaerobic pathways of substrate utilization were reversible. A yeast with new physiological features was the results. At short term action of submaximal temperatures during the time of one cell generation only minor changes in the anabolism were found and a fast return of the culture to normal parameters of growth and development was possible.
