Abstract

This study was carried out to get the basic data for the mycelial growth of Lentinus lepideus in liquid culture. The optimal temperature and initial pH of mycelial growth of Lentinus lepideus were $25^{\circ}C$ and pH 5.5, respectively. The optimal medium was YMG medium. Among the carbon sources tested, glucose was effected to the mycelial growth and optimal glucose concentration was 4% (w/v). As nitrogen sources, malt extract and yeast extract appeared to be favorable and optimal malt extract and yeast extract [ratio (w/w) of 1:1] concentration was 1.5% (w/v).

액체배양을 이용한 잣버섯(Lentinus lepideus KACC 50120)의 균사체 생육에 관한 결과로는 최적온도는 $25^{\circ}C$이고, 최적 pH는 5.5이었다. 공시배지중에서 최대 균사 생육을 보인 최적배지는 YMG 배지로 조사되었다. YMG 배지를 기본배지로 하여 영양 요구성 실험을 한 결과 탄소원 선발 및 최적 농도에서는 최적 탄소원은 glucose이고 최적 농도는 4.0%(w/v)이며 질소원 선발 및 최적 농도에서는 malt extract와 yeast extract를 혼합하여 사용하였을 때 최대 균사 생육을 보였고, 상기의 두가지 복합질소원을 1:1의 무게비로 혼합하여 1.5%(w/v)농도로 첨가하였을 때 균사생육이 가장 양호하였다.
