Abstract
Low concentrations of benzoic acid stimulated fermentation rates in Saccharomyces cerevisiae. At concentrations near the maximum permitting growth, there was inhibition of fermentation, lowered ATP and intracellular pH, and relatively greater accumulation of benzoate. Changes in the levels of glycolytic intermediates suggested that fermentation was inhibited as a result of high ATP usage rather than of lowered intracellular pH. Specific inhibition of phosphofructokinase or of several other glycolytic enzymes was not observed.
