| 摘 要： | 采用琼脂扩散法对放线菌菌株1 a发酵液进行了抗菌谱测定。结果表明,菌株1 a发酵液对9种常见植物病原真菌有很好的抑制作用,其中对人参锈腐菌抑菌活性最强,抑菌圈直径可达22 mm。稳定性测定结果表明菌株1 a发酵液低温贮藏效果好,对热及紫外光照稳定性较强,对极端酸碱环境稳定性较差。

| Abstract: | Antifungal spectrum of fermentation liquid from actinomyces strain 1a was determined by the use of agar diffusion method in the experiment.The results showed that the fermentation liquid had good inhibiting effects against nine common plant pathogenic fungi,among which the best inhibiting effect was against Cylindrocarpon destructans,the diameter of inhibition ring was 22 millimeters.Results of Stability tests showed that it had strong stabilities towards heat and UV-irradiation and should be stored in low ... |
