EFFICIENT PROPAGATION BY BIOREACTOR SYSTEM OF KOREAN NATIVE GINGER IN SEOSAN REGION

Abstract

To establish an efficient propagation method through airlift bioreactor system of Zingiber officinale Rosc. Korean native Seosanjong, the effect of different factors and bioreactors on cultured plantlets were investigated. The highest number of plantlets, fresh weight per plant was obtained from explants when cultured in MS liquid medium including 0.3 mg/L NAA and 2.0 mg/L kinetin for 40 days. A 10 L bottle type bubble bioreactor, compared with 250 ml Erlenmeyer flask, was more efficient, producing 4.7 plantlets or from 1.5 to 1.6 times more than did the Erlenmeyer flask. The results demonstrate a rapid mass propagation method for scaling up production of normal ginger using the airlift bioreactor.
