Abstract

A good mycelial growth of F. fraxinea was observed on CDA medium. The optimum temperature and pH for the mycelial growth of F. fraxinea was at $30^{\circ}C$ and pH 6.0, respectively. Glucose was found to be the best carbon source and arginine was favored as nitrogen source. When the basal medium was supplemented with organic acids, the best growth was shown in succinic acid and the poor growth was shown in oxalic acid. Thiamine.HCl showed the best results on the growth of this fungus on basal medium. Mycelial growth of F. fraxinea was quite good when oak tree sawdust was used to cultural substrates. The best mycelial growth was observed when 20% of rice bran was added as a supplement on sawdust substrates. Higher yield of F. fraxinea was observed on the medium with oak tree and acacia sawdust.

장수버섯의 배양적특징(培養的特徵) 및 인공재배(人工栽培) 가능성(可能性)에 대하여 검토(檢討)한 결과(結果) 균사생장(菌絲生長)이 가장 우수(優秀)한 배지(培地)는 CDA배지(培地)였으며, 최적온도(最適溫度)는 $30^{\circ}C$, pH는 6.0이었다. 탄소원(炭素源)은 단당류(單糖類)인 glucose를 첨가(添加)한 배지(培地)에서 가장 우수(優秀)하였고, cellobiose를 첨가(添加)한 배지(培地)에서 가장 저조(低調)하였다. 질소원(窒素源)은 arginine을 첨가(添加)한 배지(培地)에서 가장 양호(良好)하였으며 C/N 첨가비(添加比)는 glucose 3%, arginine 0.25%인 C/N비(比) 12에서 가장 적합(適合)했다. 유기산(有機酸)은 succinic acid, vitamin은 thiamine을 첨가(添加)한 배지(培地)에서 가장 양호(良好)하였다. 인공재배(人工栽培)를 위한 종균제조시(種菌製造時) 가장 적합(適合)한 것은 참나무 톱밥에 첨가재(添加材)로 미강(米糠)을 20% 첨가(添加)한 배지(培地)이었으며, 톱밥재배시(栽培時) 수량(收量)은 참나무, 아카시나무 순(順)으로 높았다.
