摘要: Resveratrol are the most important bioactive compounds found in Vitis amurensis. In this study, a somatic embryo induction system for V. amurensis was established in air-lift bioreactors for the production of biomass and resveratrol. The somatic embryos biomass growth was low on solid medium (69.60 g L-1) compared to in liquid medium in bioreactor (329.45 g L-1). Bioreactor cultures were found to be superior compared with solid medium culture not only in terms of biomass but also resveratrol productivity. Various culture parameters, including culture method, inoculum density, carbon source, and organic compounds were optimized. An inoculum density of 20 g L-1 embryogenic calli was found suitable for the accumulation of biomass and resveratrol production, whereas 10 g L-1 embryogenic calli increased the amount of resveratrol per fresh weight in somatic embryos. For bioreactor culturing, sucrose was an optimum carbon source and 500 mg L-1 casein hydrolysate acid was conducive to the biomass and resveratrol production. This result indicates that an efficient protocol for the large-scale production of resveratrol can be achieved by bioreactor culturing of V. amurensis somatic embryos and can be used as a source of medicinal raw materials.
