鸡土从菌的小白球菌阶段培养初探

通过模拟实验来研究鸡纵菌的小白球阶段的培养条件.结果表明小白球菌除需要低 p H值 (4.0一4.5) 和低浓度有机氮外,还需要多种维生素和一定的糖类,小白球菌在实验 室条件下生长良好,液体培养已获得成功,为人工利用和栽培鸡纵菌提供了一 条 可能的 途径

A Preliminary Study on the Culture of Terraitospheria duthiei

In this paper, the ecological factors and the nutrient conditions of Termitosphaeria duthiei (Berk.) Ciferri (the sporodochia stage of Termitomyces albuminosus (Berk.) Heim) are studied with the test of connidia germination and by means of a controlled environmental condition of CO2, pH, temperature, vitamin, carbohydrate, organic nitrogen, etc. The results show that,besides higher CO2 and humidity, lower pH(3.8-4.2) and organic nitrogen, the growth of Termitosphaeria duthiei requires various vitamin and carbohydrate. Termitosphaeria duthiei grows well with agar culture. Its liquid culture has been succeeded in the laboratory. It will provide a way for the artificial culture of Termitomyces albuminosus.
