Title:
GENE INVOLVED IN QUORUM-SENSING SYSTEM OF ACETIC ACID BACTERIUM, ACETIC ACID BACTERIUM HAVING MODIFICATION OF THE GENE AND GROWN, AND METHOD FOR PRODUCTION OF VINEGAR BY USING THE ACETIC ACID BACTERIUM
Document Type and Number:
Japanese Patent JP2008206413
Kind Code:
A
Abstract:

To obtain a gene involved in the acetic acid fermentation ability, to improve the acetic acid fermentation ability of an acetic acid bacterium by decreasing or eliminating the function of a protein encoded by the gene, and to provide a method for producing a vinegar having a higher acetic acid concentration with high degree of efficiency.

The gene encoding an acyl homoserine lactone synthase or an acyl homoserine lactone receptor transcription factor which is involved in the quorum-sensing of an acetic acid bacterium is obtained. The gene is modified so as to cause the decrease or elimination of the function of the quorum-sensing system in an acetic acid bacterium, thereby producing an acetic acid bacterium having a remarkably improved acetic acid fermentation ability. Provided is a method for producing a vinegar having a high acetic acid concentration with efficiency by using the acetic acid bacterium.
