The authors studied the influence of periodic variations (one cycle per 24 hr) of the feeding mash concentration of a continuous anaerobic culture of Saccharomyces cerevisiae in sugarcane molasses media at constant dilution rate. It was observed that the average yield coefficients during the transient state were practically equal to the yield coefficient obtained during steady‐state experiments. It was also observed, in each experiment, that the average specific growth rate during the transient state was equal to the dilution rate.
