Athelia rolfsii的β-甘露聚糖酶纯化研究
Purifiction of β-mannanase from Athelia rolfsii
【摘要】 从发酵培养5 d的产β-甘露聚糖酶的Athelia rolfsii菌株CBS191.62发酵液中经硫酸铵沉淀、琼脂糖凝胶(DEAE Sepharose Fast Flow)层析、羟基磷灰石(Hydroxylapatite)层析和冷冻干燥结晶等步骤,获得了比活提高了15.1倍,分子量为14.7 kD的凝胶电泳均一的β-甘露聚糖酶蛋白样品。
【Abstract】 After cultivating in liquid medium for 5 days,an extra cellular β-mannanase from Athelia rolfsii strain CBS191.62 was purified by 15.1-fold to electrophoretic homogeneity by ammonium sulfate precipitation,DEAE Sepharose Fast Flow chromatography,Hydroxylapatite chromatography and refrigeration crystal.The molecular mass of the enzyme was estimated to be 14.7 kD by SDS-PAGE
