Abstract

For the study of Hericium erinaceum as a useful functional foods and materials, liquid cultivation under two different bioreactors(air-lift fermenter and jar fermenter) which was not studied systematically until now, was conducted as a method of mass cultivation for H. erinaceum. A batch cultivation in an air-lift fermenter and a jar fermenter was examined for enhancing the productivity because of small amounts of mycelial weight and slow growth in case of a liquid culture for H. erinaceum. We found that air lift fermenter system was more effective than jar fermenter for mycelial production of H. erinaceum, and mycelial morphology was a critical factor of the growth. By scale-up and cultivation based on morphological analysis, the conditions for mass production with 30 L and 500 L jar fermenter was 200 and 150 rpm of agitation speed at 1 vvm of aeration rate, respectively, and mycelial dry weight under these conditions was enhanced to about $13{\sim}14g/L$.

H. erinaceum의 기능성 소재화 연구의 일환으로, 지금까지 체계적으로 연구된 바 없는 H. erinaceum의 액체배양을 시도하고. 이 버섯의 서로 다른 생물반응기하의 액체배양 특성을 규명하고 대량생산을 검토하였다. 5 L 용량의 jar fermenter와 air-lift fermenter에서의 액체배양의 비교실험을 통해 air-lift fermenter의 사용이 종균 배양에 적합한 것으로 나타났으며, 형태 분석을 통해 적정 크기($2{\sim}4mm$)의 pellet 형태의 유지가 대량 생산의 중요인자인 것을 규명하였다. Air-lift fermenter 하의 배양을 종균으로 하고, 적정 크기의 pellet을 유지하는 500 L까지의 jar fermenter를 사용한 회분 배양의 scale-up 실험결과, 30 및 500 L에서의 교반 및 통기속도는 각각 200 rpm, 1 vvm 및 150 rpm, 1 vvm이었다. 이 조건하에서 배양의 전 기간 중 적정 pellet을 유지하였으며, 최대 균사체량은 약 $13{\sim}14g/L$이었다.
