The effects of acetic acid and specific growth rate on acetic acid tolerance and trehalose content of Saccharomyces cerevisiae CBS 2806 were studied using anaerobic chemostat cultures. Cells grown in the presence of acetic acid at a defined specific growth rate showed a higher acetic acid tolerance and a slightly lower trehalose content. Cells grown at a low specific growth rate showed a lower energy demand, a higher acetic acid tolerance, and a higher trehalose content. These results indicate that trehalose plays a growth rate dependent role in the tolerance of S. cerevisiae to acetic acid.
