菌丝生长速度与呼吸消耗及胞外酶活性的关系

Correlations of Mycelial Growth Rates and Respiration Consumption, Extracellular Enzyme Activities

以棉籽壳为主料,对平菇、刺芹侧耳、黄伞、灵芝、金针菇和香菇原种培养期间的菌丝生长速度、呼吸消耗及胞外酶活性的关系进行了研究。结果表明,6种食用菌的菌丝生长速度与呼吸消耗正相关,而有机物的降解速率与胞外酶活性的大小没有相关性。

Correlations of mycelial growth rates and respiration consumption,extracellular enzyme activities in Pleurotus ostrea-tus,P.eryngii,Pholita adiposa,Ganoderma lucidum,Flammulina velutipes and Lentinula edodes cultivated on cotton seed hull medium were studied in stage of primary stock cultivation.The results indicated that there existed the positive correlation between the mycelial growth rates and respiration consumption,but no correlation between the degradation rates of the organic matter and the levels of extracellular enzyme activities in the six edible fungi.
