不同氮源对马鞍菌菌丝生长的影响
Journal of Anhui Agricultural Sciences（2021）
Abstract
以2种马鞍菌为供试菌株,通过对其菌丝颜色、密度、均匀度、长势、菌丝生长速度及菌丝生长指数进行比较,探讨7种氮源对2种野生马鞍菌菌丝生长的影响.结果表明,2种马鞍菌对有机氮源、无机氮源、氨基酸氮源均能利用,说明其有较广的氮源谱,但利用程度有所差异,表现为有机氮源的培养基优于无机氮源和氨基酸氮源的培养基.2种马鞍菌在以牛肉膏为氮源时,菌丝洁白、浓密、均匀,菌丝长势为5分,菌丝生长速度较快,菌丝生长指数最高,分别达到45.5和45.0.综合分析马鞍菌菌丝生长的最适氮源为牛肉膏.
