공기주입형 생물반응기를 이용하여 오미자 현탁배양세포로부터 Gomisin J의 생산 가능성을 확인 하였다. 시료의 초기접종 농도와 탄소원의 농도에 따른 세포증식과 Gomisin J의 생산성은 6% sucrose가 첨가된 MB5배지 에 100 g (FCW)의 현탁배양세포를 접종하였을 경우 세포중량 (dry biomass)과 Gomisin J의 함량은 각각 43.5 g DCW/과 $0.71;{ imes};10^{-3};{mu}g/g$ DCW을 얻을 수 있었다. 배양기내 산소의 공급량은 0.5로 공급해 주는게 바람직 할 것으로 사료되었다.
Suspension culture of Schisandra chinensis for production of gomisin J was perfomed in bioreactor. The inoculum size and initial sucrose concentration had significant effect on the cell growth and gomisin J accumulation. The maximum dry cell weight $(DCW;;43.5;g/{ell})$ and gomisin J content $(0.71;{ imes};10^{-3};{mu}g/g;DCW)$ were obtained at inoculum size of 100 g fresh cell weight (FCW) per liter and MB5 medium containing 6% sucrose after 8 weeks of culture. The effect of oxygen supply on the cell growth and gomisin J accumulation was also investigated in an airlift-type bioreactor. The optimal cell growth and gomisin J content was obtained under 0.5 vvm. The productivity of gomisin J was 0.7 fold in bioreactor culture lower than that obtained in a flask cultivation.
