Gene improving temperature-tolerance of acetic acid bacterium, acetic acid bacterium bred using the gene and process for producing vinegar using the acetic acid bacterium

摘要

The present invention is intended to provide a novel gene originating in an acetic acid bacterium, which participates in temperature tolerance; a method of improving the temperature tolerance of a microorganism, in particular, an acetic acid bacterium using the above gene; and a method of efficiently producing vinegar having a higher acetic acid concentration with the use of an acetic acid bacterium whose temperature tolerance has been improved.
