粗毛栓菌MnP的分离与纯化
摘要：粗酶液来自麦草粉固态培养物，经超滤浓缩、盐析、透析、Q- Sepharose fast flow阴离子交换层析后获得具有MnP活性的组分。
关键词：粗毛栓菌 MnP 离子交换层析
Isolation and Purification of MnP in Trametes gallica Fr.
Abstract：The crude enzyme from wheat straw solid culture of Trametes gallica Fr. was ultra-filtrated, salted-out, dialyzed and applied to Sepharose-Q Fast Flow ion exchange column. A component with manganese peroxidase activity was obtained.
Key words: Trametes gallica Fr.,Manganese Peroxidase, ion exchange chromatography.
