摘要
在实验室分离获得的放线菌A11菌株,其发酵液采用对峙培养对植物病原真菌均表现良好的抑菌活性。对发酵液在不同温度和不同pH下的稳定性进行测定,结果表明菌株A11发酵液在中性及酸碱条件下都稳定,在极酸和极碱条件下抑菌活性丧失;A11发酵液能经受75℃温度60min,仍保持原来的抗菌活性,温度升高到100℃时活性丧失。
Fermentation of strain A11 showed antagonism pathogenic fungus such as Exserohilum Helminthosporium turcicum, Colletotrichum gloeosporioide, and so on. Antifungal substances in fermentation of strain A11 can keep activity at neutral, alkaline. But antifungal substances begin to lose activity at extreme neutral and extreme alkaline. It can preserve it's inhibitory to pathogenic fungi when autoclaved at 75℃ for 60min, However, this substance was not stable ,it loses activity when temperature up to 100℃.
