土生空团菌(CenococcumgeophilumFr.)是自然界最为常见的外生菌根真菌之一。通过对其菌丝体营养生理特性的研究,报道了不同培养基,碳、氮源和pH值对于土生空团菌菌丝体生长的影响。结果表明:(1)从供试的培养基来看,MRD为最适培养基;(2)该菌在供试的C源中以葡萄糖和蔗糖利用较好;(3)N源的利用以硝酸钾效果最佳,而且该菌种也能够利用有机态的氮(即蛋白胨);(4)土生空团菌菌丝体对pH值的适应范围较广。 CenococcumgeophilumFr. Is one of the most common ectomycorrhizal fungi in nature. The effects of different media, carbon, nitrogen source and pH value on the mycelial growth of Mycobacterium aeruginosa were reported by studying the physiological and physiological characteristics of mycelium. The results showed that: (1) MRD was the best medium for the medium tested; (2) the strain was better utilized with glucose and sucrose in the C sources tested; (3) Potassium nitrate has the best effect, and the strain can also utilize organic nitrogen (peptone). (4) Mycelium of A. tumefaciens has a wide range of pH adaptation.
