Isolation and characterization of a new bacterium capable of biotransforming cis -epoxysuccinic acid to D(-) -tartaric acid.


PMID 17166227

Abstract

A bacterial strain 1-3 capable of enantioselectively hydrolyzing cis-epoxysuccinic acid to D(-)-tartaric acid was isolated from soil. Phenotypic characteristics, Biolog GN test and phylogenetic analysis of strain 1-3 indicated that it belongs to the genus Bordetella. cis-Epoxysuccinic acid could be used as a carbon source and inducer for production of cis-epoxysuccinic acid hydrolase. After the purification of the enzymatic biotransformed product, a colorless and scentless crystal was obtained, which was confirmed to be the tartaric acid with laevorotatory optical rotation by the (1)H nuclear magnetic resonance spectrum and optical rotation analysis.
