Maltose metabolism and leavening ability of baker's yeast (Saccharomyces cerevisiae) in lean dough is negatively influenced by glucose repression. To improve maltose metabolism and leavening ability, it is necessary to alleviate glucose repression. In this study, we focus on the effects of regulators (GLC7 encoding the catalytic and REG1 encoding the regulatory subunits of protein phosphatase type 1) of glucose repression on maltose metabolism and leavening ability of baker's yeast in lean dough. To this end, GLC7 and/or REG1 deletions were constructed and characterized in terms of the growth characteristics, maltose metabolism, leavening ability, and enzyme activities. The results suggest that GLC7 and/or REG1 deletions increased maltose metabolism and leavening ability at different level with glucose derepression and increased enzymes (maltase and maltose permease) activities. In a medium containing glucose and maltose, at the point of glucose exhaustion the maltose metabolized and the leavening ability were increased 59.3% and 23.1%, respectively, in the case of a REG1 single gene deletion.
