黄柄曲霉ASD 菌株抑菌谱测定及抑菌物质初探
采用对峙培养法对黄柄曲霉(Aspergillus flavipes)ASD 菌株抑菌谱进行了测定,试验结果表明:黄柄曲霉ASD 菌株具有较广的抑菌谱,对辣椒疫病(Phytophthora capsici Leonian)、番茄晚疫病菌(Phytophthora infestans)有较好的抑制作用。ASD 菌株发酵液对辣椒疫病菌的抑菌带宽度为7.4 mm,抑菌活性较强。ASD 菌株的发酵液经50% 硫酸铵饱和度沉淀并透析后得到的抑菌物质对辣椒疫病菌的抑菌效果最好,抑菌活性可达80.78%,且抑菌物质为蛋白类物质。

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.
