Abstract

|
Various conditions for mushroom were investigated to study their effects on the mycelial growth of oyster mushroom and pathogens. Our results show that the optimal pasteurization temperatures for mycelial growth and pathogens are 60℃ and 121℃ respectively. Both were then decreased by heating over 60℃ and getting down temperature under 121℃, respectively. In the experiment for pasteurization time, it was showed that both 8 and 12 hours pasteurization were greater than 24 hours treatment for the mycelial growth. In contrast, we didn´t end any particular effect by different soaking time of substrates. The pH In substrates was leveled well by pasteurization and after-fermentation even though the acidity was lowered by extending the soaking time. Our results also show that the mycelial growth is greatest at 25∼30℃ regardless of pasteurization time for substrates, Through the experiment with paddy straw as a substrate, it was showed that two time pasteurization was greater than one time for mycelium growth and pro-fermentation of paddy straw before pasteurization have resulted in worth mycelial growth compared with that of normal condition.
