Inhibition Spectrum Determination of Aspergillus flavipes ASD Strains and Primary Studies on Its Antibacterial Substance
The inhibition spectram of Aspergillus flavipes ASD strains was measured by plate confrontation  test. The results showed that ASD strains had a wide-range inhibition. It had better inhibitory effect on Phytophthora  capsici and Phytophthora infestans. The results showed that the inhibitory effect of broth of ASD strains  was pretty good on Phytophthora capsici. Its inhibitory diameter was 7.4 mm. After 50%(NH4)2SO4 saturation  precipitation of broth of ASD strains and dialysis,the antibacterial substance was obtained which showed the  best inhibitory effect on Phytophthora capsici. The inhibition effect could reach 80.78%,and moreover the  antibacterial substance was albuminoidal substances.
