Provided herein are a method for selecting a gene participating in the desired brewing character and compiling a database of the whole genome sequence of industrial yeast; identifying a gene participating in a brewing characteristic from the database; functional analysis of the gene; and a DNA array of the whole genome sequences of an industrial yeast. Also provided are a method for yeast breeding; a method of producing an alcoholic beverage with improved quality; and a screening method to identify genes that increase productivity and/or improve flavor in the production of an alcohol or an alcoholic beverage by (A) analyzing a whole industrial yeast genome sequence, (B) comparing the genome sequence with the genome sequence of, (C) selecting a gene of the industrial yeast encoding having 70 to 97% identity to an amino acid sequence of; and (D) analyzing the selected gene.

Screening method for genes of brewing yeast

This invention provides a process for producing ethanol from a starchy material, wherein the starchy material is simultaneously subjected to saccharification and subsequent fermentation by use of a yeast host which has been transformed by an expressible recombinant vector comprising a glucoamylase gene derived from a fungus of the genus Rhizopus.

Process for producing alcohol using yeast transformed by Rhizopus

The present invention relates to the Rhizopus derived glucoamylase gene, a novel recombinant vector comprising said gene, and a microorganism transformed by said vector, as well as a process for reproducing Rhizopus glucoamylase by cultivating the transformed microorganism, especially yeast, in a liquid medium.
