Abstract

Addition of NH+ 4 in the presence of glucose to washed suspensions of Saccharomyces uvarum, Schizosaccharomyces pombe or Candida utilis greatly increased glycolytic CO2 production and slightly stimulated respiration. In all three organisms the ammonium ion effect was distinguishable from the effect of an uncoupler of aerobic energy conservation (carbonyl cyanide m-chlorophenylhydrazone; CCCP). The Pasteur effect (aerobic inhibition of glycolysis) in the fermentative yeasts also proceeded independently of the ammonium ion effect. Possible control mechanisms are discussed.
