Abstract
The present invention provides a method for producing an yeast having an increased cellulose hydrolysis ability. The method includes the step of introducing increased integration copy numbers of both a gene for an enzyme capable of hydrolyzing crystalline cellulose and a gene for an enzyme capable of hydrolyzing noncrystalline cellulose into a noncellulolytic yeast to give a transformed yeast. The yeast having an increased cellulose hydrolysis ability can be suitably used for ethanol production from cellulose-based materials.
