In order to separate a type of antifungal protein from Bacillus subtilis Zl-2,and investigate its antifungal effects,we use the crude protein of Zl-2 to precipitate with ammonium sulfate(( NH4)2 SO4).The stability of antagonistic protein under different conditions,such as temperature,p H value,ultraviolet and protease,was investigated to understand the antifungal effects mentioned above. The antifungal activity was measured by Fusarium graminearum as an indicator. The results showed that the antifungal prot...
