摘要

This study was carried out to investigate the effect of NO_3 and NH_4~+ on the adventitious root growth and eleuthroside synthesis of Eleutherococcus koreanum in 5 L-bioreactor culture. The change in the medium components was also measured during culture. The fresh weignt of adventitious root reached to the highest level. of 30.8 g FW/L in the presence of both 50 mM NO_3~- and 10 mM NH_4~+, representing 3.6-fold increase compared to the 60 mM NH_4~+ alone. However, as the increase of the portion of NH_4~+, the root growth was decreased. However, the maximum eleutheroside B, E and El contents were 57.3 (ig/g DW, 188.4 ug/g DW and 47.3 mu g/g DW, with 30 mM, 60 mM and 15 mM total nitrogen source, respectively. Fresh weight of adventitious root increased up to 6.8-fold of inoculum size within 9 weeks. The amounts of NH_4~+ K~+ NO_3~- and PO_4~- were decreased during culture periods. Based on these results, we suggest that various further studies are required to increase the biomass and the useful secondary metabilites.
