Abstract

See full text

The present invention provides a D-glucaric acid-producing bacterium and a method for producing D-glucaric acid. The present invention is characterized in that D-glucaric acid or a salt thereof is produced from one or more saccharides selected from the group consisting of D-glucose, D-gluconic acid and D-glucuronic acid with catalytic action of a specific alcohol dehydrogenase PQQ-ADH (1) and a specific aldehyde dehydrogenase PQQ-ALDH (2), and that D-glucaric acid or a salt thereof is produced by using a microorganism having the PQQ-ADH (1) and the PQQ-ALDH (2) or a processed product thereof in the presence of the one or more saccharides. The present invention can provide a microorganism having improved productivity of D-glucaric acid to be used for production of D-glucaric acid and a method for efficiently producing D-glucaric acid.
