This study was carried out to investigate the optimal mycelial growth and an artificial cultivation conditions of Pleurotus eryngii. The optimal medium for the mycelial growth and density was MYPA medium. The optimal temperature and pH for the mycelial growth were 25℃ and 6.0, respectively The modified optimal medium composition were obtained to be soluble starch 3% (w/v), malt extract 0.25% (w/v), yeast extract 0.25%(w/v) and CaCl₂·2H₂O 0.05%(w/v). From the results of experiment on the nutritional requirements, the modified optimal medium was higher than MYP medium in mycelial production and growth yield (Yx/s) of Pleurotus eryngii. The optimal sawdust species of solid culture for the mycelial growth and density was Quercus spp. The optimal concentration of additives (rice bran and wheat bran) and moisture content for the mycelial growth were about 30% (v/v) and 70%(v/v), respectively. On the other hand, the optimal concentration of additives for the production of fruiting body was 20%(v/v) of rice bran.22
