Abstract
The growth of 14 strains of food microorganisms in the normal and K-deficient media was examined. In 9 strains of them, the considerable growth was recognized in both the normal and K-deficient media. The percentage of the weight of the dried cells of these 9 strains cultured in the K-deficient media against that cultured in normal media was observed to be 16.8-95.3. In 6 or 8 repeated experiments, the relation between the weight of dried cells of Saccharomyces cerevisiae, Saccharomyces ellipsoideus and of Aspergillus niger, and the amount of fermentation products (ethanol, total-, volatile- and nonvolatile acids) with their growth, and the amount of glucose consumed by them, cultured in the normal and K-deficient media was examined. The efficiency of the production of the fermentation products by them in K-deficient media was observed to be equal to, or higher than, that in the normal media.
