Influence of pH on Inhibitory Activity of Acetic Acid on Osmophilic Yeasts Used in Brine Fermentation of Soy Sauce.
The inhibitory activity of acetic acid on osmophilic yeasts (Saccharomyces rouxii and Torulopsis versatilis) used for the brine fermentation of soy sauce increased remarkably as the pH of the medium was lowered. This increased toxicity could not be attributed to a hydrogen ion effect alone.
