<P>PROBLEM TO BE SOLVED: To improve a usage rate of raw materials in production of liquors, such as refined rice wine (sake) and distilled liquor (shochu), and to reduce production costs thereof. <P>SOLUTION: The liquors are produced by utilizing a yeast which highly produces polygalacturonase. A strain which is formed by combining a polygalacturonase gene derived from Aspergillus kawachii with a vector and then transforming the obtained recombinant vector into a tryptophan-demanding strain [e.g., TIPgaA(FERM P-19552) or TIPgaB(FERM P-19553)] is, for example, used as the yeast. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
