Abstract
The rate of fermentation of both d-glucose and maltose in a defined medium by a brewing strain of Saccharomyces cerevisiae was found to be dependent on the availability of NH4+. The glycolytic rate did not correlate with intracellular NH4+ and activation by NH4+ was blocked by cycloheximide. The ability of several amino acids to activate glycolysis followed the same order as their effectiveness as sole sources of nitrogen. It therefore seems that NH4+ does not stimulate fermentation through direct activation of glycolytic enzymes, but through its function as a substrate for protein synthesis. © 1984.
