Abstract

Pleurotus ferulae is an edible mushroom found on a medicinal plant, Ferula assa-foetida, in centeral China. This study was carried out to investigate the cultural characteristics of P. ferulae strains. Characteristics of mycelial growth were investigated for 5 strains of P. ferulae. All the 5 strains showed the best mycelial growth at $25^{\circ}C$ and their growth rate was very low at $35^{\circ}C$. The colony diameter reached to 45~72 mm after 7 days at $25^{\circ}C$. Malt extract agar medium was the best for mycelial growth of the species both in hyphal length and density. Mycelial growth was not affected by various pH from 6.0 to 8.0. An optimal carbon source was arabinose and an optimal nitrogen one was arginine. And an effective substrate for the mycelial growth was 8 to 2 mixture of oak sawdust and cottonseed meal.

본 연구의 목적은 온도, pH, 탄소원, 질소원 그리고 기질에 따른 아위버섯(Pleurotus ferulae )의 균사 생장 특성을 이해하는 것이었다. 아위버섯의 균사생장에는 MEA(malt extract agar)배지가 가장 효과적이었고, 균사생장에 최적온도 범위는 $25{\sim}30^{\circ}C$, 최적 pH는 6.0~8.0 이지만 균주에 따라 차이가 있었다. 아위버섯 균사 생장에 효과적인 탄소원으로는 arabinose, 질소원으로는 arginine 이었다. 그리고 균사생장에 효과적인 기질은 참나무 톱밥과 면실피를 8: 2의 비율로 섞은 배지였다.
