Fig. 1From: Synergistic production of 20(S)-protopanaxadiol from protopanaxadiol-type ginsenosides by β-glycosidases from Dictyoglomus turgidum and Caldicellulosiruptor bescii Optimization of a the concentration of total protopanaxadiol (PPD)-type ginsenosides in ginseng root extract as substrates; b the concentration of the β-glycosidase from Dictyoglomus turgidum (DT-bgl) as an enzyme for 20(S)-protopanaxadiol (APPD) production; and c the time-course reactions for the production of APPD from PPD-type ginsenosides in ginseng root extract by DT-bgl alone under the optimal conditions.
