Gene associated with foam formation of acetic acid bacterium, acetic acid bacterium bred by modifying the gene and method for producing vinegar using the acetic acid bacterium

摘要

The present invention provides a method for reducing or deleting the function of a protein encoded by the glyT gene in an acetic acid-producing bacterium. This method significantly suppresses foam formation during the culture and enhances the acetic acid fermentation ability of the bacterium.
