The growth-temperature relations and thermal tolerance of the asexual spores of thermophilic fungi commonly found in composting plant materials were determined. The optimum temperature range for germination of the spores was 40 degrees - 50 degrees C. The spores of Humicola lanuginosa (GRIFFON and MAUBLANC) BUNCE were able to survive 60 min exposure to 68 degrees C while those of Mucor pusillus COONEY and EMERSON survived only 5 min exposure to 68 degrees C. A determination of the thermal death rates of the spores at 65 degrees C showed a rapid loss of viability of those of Torula thermophila COONEY and EMERSON. The thermal tolerance of the propagules of thermophilic fungi in relation to their special ecological niche is discussed.
测定了堆肥植物材料中常见嗜热真菌无性孢子的生长温度关系和耐热性。孢子萌发的最佳温度范围为40℃ - 50℃。毛绒嗜热放线菌（GRIFFON和MAUBLANC）BUNCE的孢子在68℃下暴露60分钟仍能存活，而微小毛霉COONEY和EMERSON的孢子在68℃下仅暴露5分钟就死亡。在65℃下对孢子热死亡率的测定表明，嗜热球拟酵母COONEY和EMERSON的孢子活力迅速丧失。讨论了嗜热真菌繁殖体的耐热性与其特殊生态位的关系。
