<P>PROBLEM TO BE SOLVED: To provide a novel gene associated with proliferation promoting functions of acetic acid bacteria, a microbe containing the gene, and to provide a method for enhancing rate of acetic fermentation of the acetic acid bacteria, and to provide a method for effectively producing vinegar with high acetic acid concentration by using the acetic acid bacteria which has the enhanced fermentation rate. <P>SOLUTION: The gene having functions enhancing the acetic acid fermentation in practical level is cloned from a practical acetic acid bacterium belonging to the genus Gluconacetobacter and Acetobacter according to a method for obtaining a gene shortening times required for culturing in a medium containing acetic acid from a chromosomal DNA library of the acetic bacterium. In a transformant in which the gene is transduced into the acetic acid bacteria, culturing the transformant in the presence of ethanol remarkably enhances the rate of acetic acid fermentation. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
