Studies on Osmophilic Yeasts

Abstract

The author has conducted studies on the nutritional requirement of yeasts in environ-ments of both an ordinary and a high concentration of sodium chloride. During the course of these experiments, it was found that the pH range for the growth of the tested yeasts in the NaCl-free medium was in a very wide range (pH 3.0_??_7.0), while that in the NaCl 18% medium was limited in the range of pH 4.0_??_5.0. In addition to the results described in the previous paper, ¹⁾ the difference between the salt-tolerance and sugar-tolerance of the osmophilic yeasts was also shown in respect of this pH dependence.
