Original Paper


Biotransformation of ginsenosides was examined using lactic acid bacteria isolated from several kinds of kimchi. A Gram-positive, facultatively anaerobic, non-motile, non-spore-forming, and rod-shaped lactic acid bacterial strain, designated EMML 3041T, was determined to have ginsenoside-converting activity and its taxonomic position was investigated using a polyphasic approach. Strain EMML 3041T displayed β-glucosidase activity that was responsible for its ability to transform ginsenoside Rb1 (one of the dominant active components of ginseng) to F2 via gypenoside XVII, ginsenoside Rb2 to compound Y via compound O, ginsenoside Rc to compound Mc via compound Mc1, and ginsenoside Rd to ginsenoside F2. On the basis of the 16S rRNA gene sequence similarity, strain EMML 3041T was shown to belong to the genus Lactobacillus and is closely related to Lactobacillus versmoldensis KU-3T (98.3 % sequence similarity). Polyphasic taxonomy study confirmed that the strain EMML 3041T represents a novel species, for which the name Lactobacillus ginsenosidimutans sp. nov. is proposed, with EMML 3041T (=KACC 14527T = JCM 16719T) as the type strain.
