In this study, we isolated two species of bacteria for the powerful biotrasnformation of ginsenosides from Kimchi and human feces. Using biochemical tests and 16s rRNA sequencing, the selected strains were identified as Latobacillusplantarum (CKDHC0801) and Lactobacillussakei (CKDHC0802). Changes in cell growth and pH were examined in red ginseng. CKDHC 0801 and CKDHC 0802 reached their maximum growth phase after 24 hr and 48 hr, respectively, whereas the combined culture of CKDHC 0801 and CKDHC 0802 showed higher cell growth than bacterial strain alone. During fermentation of CKDHC 0801 and the combined culture, the pH values decreased from 5.2 to 4.2 after 24hr, but CKDHC 0802 reached pH of 4.2 after 3day. The identities of ginsenosides were biotransferred from high molecular (Rg1 and Rb2) to low molecular (Rg3, Rg5, Rk1, PPD) by fermentation of both bacteria. Therefore, the results of this study demonstrate that CKDHC 0801 and CKDHC 0802 could be used to enhance to effects of red ginseng.
