Title:
GENE INVOLVING PROLIFERATION-PROMOTING FUNCTION OF ACETIC ACID BACTERIUM, ACETIC ACID BACTERIUM BRED BY USING THE SAME GENE AND METHOD FOR PRODUCING VINEGAR BY USING THE SAME ACETIC ACID BACTERIUM
Document Type and Number:
Japanese Patent JP2007236203
Kind Code:
A
Abstract:

To provide a method for efficiently producing vinegar containing acetic acid in a high concentration in a short time by obtaining a new gene encoding a protein having a proliferation promoting function of acetic acid bacterium in the presence of a high-concentration acetic acid, enhancing proliferation-promoting function of acetic acid bacterium, developing an acetic acid bacterium in which high-concentration acetic acid fermentation ability is improved and using the developed acetic acid bacterium.

A new gene having a function capable of improving proliferation promoting function in a practical level is cloned from a practical acetic acid bacterium belonging to the genus Gluconacetobacter by a method obtaining a gene having a function promoting proliferation of the acetic acid bacterium in the presence of acetic acid by exposing a crushed liquid of bacterial cell of acetic acid bacterium in the presence of a high-concentration acetic acid and acquiring a gene of soluble protein not causing insolubilization by the exposure. In a transformed strain introducing the gene into the acetic acid bacterium, when the transformed strain is cultured in the presence of acetic acid and ethanol, remarkable proliferation promotion effect is confirmed.
