Purification and characterization of a β-glucosidase from the phytopathogenic fungus Fusarium oxysporum f. sp. melonis

Fusarium oxysporum f. sp. melonis produces cellulase and β-glucosidase activities in a medium with glucose and avicel as carbon source. A β-glucosidase from this crude material was purified by gel filtration and ion exchange chromatography successively. This enzyme is a unique band of protein in SDS...
