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

It is intended to provide a method for suppressing foam formation by identifying a gene associated with foam formation during acetic acid bacterial culture and decreasing or deleting the function of a protein encoded by the gene; a method for more efficiently producing vinegar containing a high content of acetic acid by using an acetic acid bacterium with which foam formation is suppressed by employing the method; and vinegar produced by the production method. The acetic acid bacterium with which foam formation is suppressed by obtaining a gene encoding a protein associated with foam formation during acetic acid bacterial culture, and modifying the gene thereby altering the function of the protein associated with foam formation such that the function is decreased or deleted was obtained. Further, the method for efficiently producing vinegar containing a higher content of acetic acid using the acetic acid bacterium is provided.
