摘　　要：嗜热真菌是蘑菇堆肥二次发酵后培养阶段的主要微生物类群。它们在堆肥中的数量及活性与蘑菇的产量有很大的相关性。本文综述了近年来，国外以嗜热色串孢（Ｓｃｙｔａｌｉｄｉｕｍｔｈｅｒｍｏｐｈｉｌｕｍ）为典型种，研究其对蘑菇菌丝促生作用的生物机制的主要成果，国外主要研究了嗜热色串孢在堆肥中的分布、数量，生长动力学特性以及呼吸机制等，同时发现嗜热色串孢的呼吸作用形成适宜的ＣＯ２浓度可使得蘑菇菌丝尽早占料，获取生态优势，本文还介绍了国内有关嗜热真菌的研究及应用。Thermophilic fungi are the dominant species among all kinds of microorganisms in mush-room compost during the temperature-controlled process of phase Ⅱ. The amount and activity of the fun-gal mycelium have been observed to be positively correlated with mushroom yield. This article summaries the recent research on the mechanisms by which thermophilic fungi promote thehyphal growth of Agaricus bisporus. In order to study the growth-promoting effect by these fungi, Scytal-idium thermophilum was used as a model organism to investigate its distribution and amount in compost,growth characteristics,respiration pathway. The results showed that the concentration of CO2 was an im-portant parameter that influenced the hyphal extension rates of Agaricus bisporus. The research in China was also presented.
