- Abstract
- Biotransformation of ginsenosides by microorganisms alters the absorption and bioavailability of ginseng as a medicinal herb. In this study, we isolated two kinds of fermenting microorganisms from Eoyukjang, which is a traditional Korean fermented food made from soybean. Next, we identified and detected their ability to convert major ginsenosides to compound K. The two microorganisms, referred to as R2-6 and R2- 15, had 100% similarity with Lactobacillus plantarum subsp. plantarum ATCC 14917T and Lactobacillus rhamnosus JCM 1136T, respectively. The optimal pH and growth temperature of the isolates were determined to be pH 6-7 and 30℃. After fermentation for 30 days, the major ginsenosides in the mountain-cultivated ginseng were transformed to the highly bioactive ginsenoside, compound K, in the final product.
