Abstract: The effect of pressure on intracellular trehalose concentration of Saccharomyces cerevisiae was primarily explored. The results showed: pressure valve, treating time, treating temperature, pH and culturing time showed evident effects on Saccharomycesc erevisiae intracellulart rehalose concentration. Theree xistedc ertainr elativity between trehalosec oncentration and viability of yeast cells, while the changes of intracellular trehalose concentration of Saccharomyces cerevisiae resulted not only from pressure valve but also from acidification and anaerobic function.

Key words: pressure, Saccharomyces cerevisiae, trehalose, carbon dioxide
