Title:
HIGH-VITAMIN B2-PRODUCING BACILLUS NATTO AND NATTO PRODUCED USING THE BACILLUS NATTO
Document Type and Number:
WIPO Patent Application WO/2008/056535
Kind Code:
A1
Abstract:
It is intended to provide a method for producing natto with increased vitamin B2 content by breeding and developing a Bacillus natto with an improved vitamin B2 productivity and producing natto using the Bacillus natto; and the natto. A Bacillus natto capable of producing natto with increased vitamin B2 content can be obtained by selecting the Bacillus natto with an improved vitamin B2 productivity after giving a histidine analog-resistant property or a histidine requiring property to a Bacillus natto. Further, a method for producing natto with increased vitamin B2 content by producing the natto using the Bacillus natto and the natto produced by the production method are provided.
