Abstract

A strain which can produce antifungal protein was isolated from soil and was identified as Aspergillus giganteus,numbered AF-11,through morphologic observation and molecular biology experiments.It has been proven that the high activity and purity antifungal protein(AFP) which can obviously inhibit the growth of filamentous fungi such as Penicillium,Aspergillus and Fusarium,can be separated from the fermentation supernatant by using cellulose cation exchange column chromatography and gelatin column chromatography.

Key words： Aspergillus giganteus; antifungal protein; ddentification; purification
