Title:
酢酸菌のクオラムセンシングシステムに関与する遺伝子、該遺伝子を修飾して育種された酢酸菌、及び該酢酸菌を用いた食酢の製造方法
Document Type and Number:
Japanese Patent JP4616296
Kind Code:
B2
Abstract:
The object of the present invention is to provide a method for efficiently producing vinegar that contains a higher concentration of acetic acid, wherein a gene involved in the acetic acid fermentation ability is obtained, the acetic acid fermentation ability of an acetic acid bacterium is improved by reducing or deleting the function of the protein encoded by the gene. An acetic acid bacterium with a remarkably improved acetic acid fermentation ability was obtained by obtaining genes encoding an acyl homoserine lactone synthase and an acyl homoserine lactone receptor-type transcription factor that are involved in the quorum-sensing system in the acetic acid bacterium, and modifying the genes so as to reduce or delete the function of the quorum-sensing system. Further provided is a method for more efficiently producing vinegar containing a higher concentration of acetic acid by using the acetic acid bacterium.
