Studies on the Effect of Korean Ginseng Components on Alcoholic Frementation by Yeast 1. Effect on the physiology of Yeast

The effect of ginseng extract and ginseng saponins on alcoholic fermentation was studied 1. Alcoholic fermentation on gllicose medium at 30$^{\circ}C$. by Saccharomyces coveanus and Saccharomyces uvavum was stimulated when the media contained 5% and 10 % of ginseng extract, respectively. But that of Saccharomyces cerevisiae was inhibites by the addition of 10% of ginseng extract. 2. Saponin did not stimulate the alcoholic fermentation by Saccharomyces uvarum. 3. The yeast cell counts was increased remarkably by addition of ginseng extract while that of ginseng saponins was increased slightly. Dried cell weight of the broth which Contained 5% of ginseng extract was 3 times than that of control.
