F.层析柱，获得具有木质素过氧化物酶活性的组分。 关键词：粗毛栓菌，木质素过氧化物酶，离子交换柱层析 Separation and Purification of Lignin Peroxidase in Trametes gallica Abstract： Trametes gallica was cultivated in wheat straw powder for 60 days. The crude enzyme by ultrafiltrating, salting and dialysis, was applied to Q-Sepharose FF ion exchage column. The effluent with Lignin peroxidase acticity was obtained.
