ABSTRACT:
A process for producing a saccharide carboxylic acid or a salt thereof characterized in that a microorganism belonging to the genus Pseudogluconobacter and capable of oxidizing a hydroxymethyl group and/or hemiacetal hydroxyl-associated carbon atom to a carboxyl group, or an artifact derived from the microorganism, is permitted to act on a hydroxymethyl and/or hemiacetal hydroxyl-containing saccharide or saccharide derivative to produce and accumulate the corresponding carboxylic acid and the carboxylic acid so accumulated is harvested and novel saccharide carboxylic acids produced by the above production method, and by the process, from a broad range of saccharides, saccharic acids having carboxyl groups derived from hydroxymethyl and/or hemiacetal OH groups can be produced with high selectivity and in good yield, the resultant saccharide acids are resistant to enzymatic degradation and have improved water solubility, among other characteristics.
