Background : The study about cultured wild ginseng root (Panax ginseng C. A. Meyer) have been reported mainly ginsenosides in saponins family. However metabolites of fermented wild ginseng roots by microorganisms was not reported yet. Methods and Results : Cultured wild ginseng roots were used for fermentation of ginseng roots using Pediococcus pentosaceus and other bacterial strains. We analyzed different types of ginsenoside contents, metabolite and enzyme contents, and gene expression by using microorganisms. Results showed considerable differences in ginseonoside contents specially Rk1 and Rg5. The highest enzyme activity level was by Glutathione reductase (GR) and Glutathione S transferase (GST) in fermented ginseng roots than control (non-fermented), whereas Glutathione peroxidase (GPX) and Peroxidase (POD) contents were reduced. Score plots and loading plots of principal components 1 of the PCA result obtained from the data on 43 metabolites in fermented wild ginseng root of five conditions. The concentration of metabolite such as β-alanin and 4-aminobutyric acid (GABA), which is used to improve memory were increased in fermented ginseng roots than control. We found functional gene in wild ginseng root related with metabolic process. The APX gene expression gradually increased in fermented ginseng root with respect to fermentation times. Conclusion : In this study, accumulation of functional metabolite in cultured ginseng r
