The effect of Ganoderma lucidum extract on Saccharomyces cerevisiae growth and physiology has been investigated. S. cerevisiae was inoculated in Henneberg solution medium into which 0, 0.1, 0.5 or 1.0% extracts of G. lucidum were added respectively and it was fermented at $30^{\circ}C$ for 5 days, respectively. Cell number of S. cerevisiae has increased according to the concentration as in order of distilled water(Dw) extracts 1.0% added>ethanol(Et) extracts 1.0% added>Dw extracts 0.5% added>Et extracts 0.5% added>Dw extracts 0.1% added>Et extracts 0.1% added group compared to control group(extracts 0% added) and in Dw extracts 1.0% added group the number has increased than those of control group after the fermentation of 72 hours. Weights of dried yeast cell have increased in each treated group than those of control group and it increased about 1.7 times in each Dw 1.0%, Et 1.0% group than those of control group after fermentation of 120 hours. The more the extracts of G. lucidum was added, the more alcohol levels increased during fermentation. The rate of carbon dioxide production per G. lucidum extract medium was faster than those of control group as G. lucidum extract was increasingly added.
