|
Some factors effecting on mycelial growth and cultural substrates using pine sawdust were investigated to develop an artificial cultivation technique. The optimal temperature and media pH for the mycelial growth were at 25℃ and 4.0, respectively. The mycelial growth was not different among three isolates tested. Among them ASI 19003 isolate showed the highest mycelial density and fruitbody yield. Among supplements added into pine sawdust, wheat bran was the best and its appropriate percentage was 20 for the mycelial growth. The mycelial densities were uprisen according to the amounts of the supplement. The highest yield, 107g/bottle of the sporophores of the mushroom was obtained from the substrates supplemented by 30% of wheat bran, but no fruitbody was formed on non supplemented one. Optimal moisture contents of the substrates was different for the mycelial growth, pinheading and fruitbody yields. Sixty five, 60 and 75% of moisture contents of the substrates were optimal for the mycelial growth, pinheading and fruitbody yields, respectively.
