Disruption mutant Paenibacillus polymyxa ZJ-9-DELTAdudA is used for production of (R,R)-2,3-butanediol of ultra-high optical purity, and without parts of meso-2,3-butanediol, through (R,R)-butanediol dehydrogenase (EC 1.1.1.4). Paenibacillus polymyxa is a microorganism with a reported potential for the industrial production of (R,R)-2,3-butanediol. Gene dudA, the gene encoding DAR, is the key factor responsible for the formation of meso-2,3-butanediol, thus reducing the purity of (R,R)-2,3-butanediol -, 762810
