Abstract

This study was carred out to get the basic conditions for the mycelial growth of Morchella esculenta in shaking flask culture. The optimal temperature and initial pH of mycelial growth of Morchella escuzenta were 25$\pm$1$^{\circ}C$ and 6.5, respectively. The optimal medium was BG medium. Among the carbon sources tested, fructose was favorable for the mycelial growth and optimal fructose concentration was 5.0% (w/v). As nitrogen sources, peptone and NH$_4$Cl appeared to be favorable and optimal concentration was 4.0% [(w/v), ratio of 1:1].

곰보버섯(Morchella esculenta)은 맛과 영양이 풍부한 버섯으로 전 세계적으로 분포하는 버섯이다. 현재까지 우리나라에서 곰보버섯에 관한 체계적인 연구가 이루어지지 않은 상태에서 본 연구는 곰보버섯(자실체) 인공대량 생산방법 개발 및 심부배양을 통한 균사체 및 다당체 대량생산 공정개발을 위한 기초자료를 얻고자 shaking flask culture를 이용한 곰보버섯 균사체 배양특성에 관하여 조사하였다. 곰보버섯 균사체의 최적 배양온도는 $25^{\circ}C$이며, 최적 초기 pH는 6.5, 최적배지는 BG 이었다. BG 배지를 기본배지로 하여 영양 요구성 실험을 한 결과 최적탄소원은 fructose이고 최적농도는 5.0% (w/v)이며 질소원 선발 및 최적농도에서는 peptone과 NH$_4$Cl를 혼합하여 사용하였을 때 최대 균사체생육을 보였고, 상기의 두 질소원을 1:1의 무게비로 혼합하여 4.0% (w/v) 농도로 첨가하였을 때 최대 균사생육을 보였다.
