초록

발효기에서의 균사체 생장과 세포외다당류의 생산을 위한 최적 배양조건을 조사하기 위하여 회분식 반응기를 이용하여 연구한 결과 최적 회전속도와 통기량은 각각 200 rpm과 1.5 vvm 었다. 최적 배양 환경하에서 5L발효기(working volume 2 L)에서 배양한 결과 각각 10.21 g/L 와 3.56 g/L의 mycelial growth와 exo- polysaccharide를 얻었다.

The Study was carried out to investigate in the optimal mycelial growth and Exo-Polysaccharides of Fomitopsis pinicola. Jar fermentations were carried out to optimize the culture conditions for mycelial growth and exo- polysaccharide production. The optimal agitation speed and aeration rate were 200 rpm and 1.5 v.v.m., respectively. Under optimal culture conditions, the maximum mycelial growth and exo-polysaccharide production after 11 days with a 5 L jar fermenter containing the optimized medium were 10.21 g/L and 3.56 g/L, respectively. However, the fundamental information obtained this study is insufficient in the development of a efficient process for mycelial growth and exe-polysaccharide production from Fomitopsis pinicola.
