생물반응기를 이용한 Lilium Iongiflorum ‘Geogia’의 대량번식

자구를 형성 및 비대시키기 위하여 BA 0.5 mg/L와 IAA 0.5 mg/L가 첨가된 MS 배지에서 Lilium longiflorum ‘Geogia’의 신초를 증식하였다. 증식된 신초 cluster를 5 L air lift 생물반응기에 배양하였다. 자구비대는 sucrose 60 g/L 및 1～2배 사이의 MS 배지 염류농도에서 효과적이었다. 재료 투입량은 100 g을 투입하는 것이 자구형성 및 자구비대에 적절하였다. 배양방법은 air-lift 방법이 자구의 형성 및 비대를 촉진하였으며, 주입공기량은 200～300 mL․min-1을 주입하는 것이 자구비대에 효과적이었다. Shoot clusters were induced from bulb scales of Lilium longiflorum Geogia', and proliferated on medium containing 0.5 mg/L BA and 0.5 mg/L IAA. Thereafter, these shoot clusters were cultured in 5 L air-lift bioreactors to form and grow normal bulblets. Number of bulblets increased on medium with 30 g/L sucrose, but growth of bulblets was effective on medium with 60 g/L sucrose. The number of bulblets from shoot clusters had no differences, though bulblet growth was very effective on medium with between full and double strength of MS salts. The inoculation of 100 g shoot clusters as a cultural material was suitable for formation and growth of bulblets in 5 L bioreactors. Air-lift type was more effective for the formation and growth of bulblets than that in ebb and flood one, and 200∼300 mL·min-1 injection of air was suitable in growth of bulblets.
