粗毛栓菌漆酶的分離與純化
摘要:將粗毛栓菌接種在含有麥草粉的培養基中培養25d,過濾得粗酶液,爾后經超濾、鹽析、離心、透析、濃縮,將透析液上樣于Q-Sepharose F. F.層析柱,獲得具有漆酶活性的組分,并測定上柱前、后漆酶的酶活力,以及溶液中的蛋白含量,從而測定漆酶的回收率和純化度。
關鍵詞: 粗毛栓菌;漆酶;離子交換層析
Sepration and Purification of Laccases in Trametes gallica
Abstract: Trametes gallica was cultivated in wheat powder for 25 days. The crude enzyme was ultrafiltrated, salted out , centrifugaled, dialyzed and concentration was applied to Q-Sepharose F.F. ion exchange column. The effluent with laccase acticity was obtained, Determine the column before and after the laccase enzyme activity and protein content of the solution to determine the recovery rate and purification degree of laccase.
Key words: Trametes gallica; laccase; ion exchange chromatography
