Rim15p of the yeast Saccharomyces cerevisiae is a Greatwall-family protein kinase that inhibits alcoholic fermentation during sake brewing. To elucidate the roles of Rim15p in barley shochu fermentation, RIM15 was deleted in shochu yeast. The disruptant did not improve ethanol yield, but altered sugar and glycerol contents in the mash, suggesting that Rim15p has a novel function in carbon utilization.
