Scytalidium thermophilum is an important thermophilic fungus in the production of mushroom compost. I investigated the characteristics of this organism and present a simple model with which fungal growth in compost can be described. The model is used to predict better circumstances for rapid indoor production of mushroom compost. I conclude that inoculation of the starting material with prepared compost either before or after the pasteurization phase has only a minor effect on the shortening of the composting process. This is because the initial growth rate of the fungus is much higher than its growth rate later. A lower temperature (53.5 degrees C instead of the usual 56 to 58 degrees C) during the pasteurization phase may be most profitable for rapid compost production; such a temperature may reduce the time that is needed for the last phase of the production process by at least 1 day.
嗜热枝孢菌是生产蘑菇堆肥的一种重要嗜热真菌。我研究了该生物体的特性，并提出了一个简单的模型来描述堆肥中的真菌生长。该模型用于预测在室内快速生产蘑菇堆肥的更好条件。我的结论是，在巴氏消毒阶段之前或之后，用制备好的堆肥接种起始材料，对缩短堆肥过程的影响很小。这是因为真菌的初始生长速度远高于其后的生长速度。巴氏消毒阶段的较低温度（53.5 摄氏度，而不是通常的 56 到 58 摄氏度）可能最有利于快速堆肥生产；这种温度可以将生产过程的最后阶段所需的时间至少缩短 1 天。
