Beschreibung
Zusammenfassung:	The invention discloses a strain producing antifungal proteins, a method for screening the strain producing the antifungal proteins and a method for producing the antifungal proteins by fermenting the strain. The strain screened with the method is called as huge aspergillus Aspergillus giganteus AF-11 with the preservation number of CGMCC NO. 4342, and the strain has higher yield of the antifungal proteins. The antifungal proteins produced from the screened strain with the method disclosed by the invention can effectively inhibit the mildew during the malting barley production, in particular the fusarium, so as to improve the quality of malts; compared with the traditional processing method, the method disclosed by the invention is safer and more effective. In addition, the invention has a favorable application prospect.
