| 摘 要： | 测定了白蚁链霉菌（Streptomyces termitum）ACT-2菌株的抗菌谱．结果表明：ACT-2菌株对细菌类病原体有较强的拮抗能力，对真菌类病原菌抑菌效果不显著．以水稻白叶枯病菌（Xanthomonas oryzae pv．oryzae）P6生理小种为指示菌，分析了ACT-2菌株发酵液的抑菌稳定性．ACT-2菌株发酵液抑菌稳定性实验显示：在温度低于80℃，4000lx光照强度下，ACT-2菌株发酵液能保持稳定的抑菌能力；温度高于90℃时，其发酵液的抑菌能力开始降低；经酸碱处理后，其发酵液的抑菌能力出现了明显的降低．

| Abstract: | The results of bacteriostasis experiments demonstrated that strain ACT-2 suppressed a wide range of bacterial pathogens in vitro,while no obvious antimicrobial activities towards fungal pathogens.Antibacterial stability of Streptomyces termitum strain ACT-2 fermentation broth was studied while Xanthomonas oryzae pv.oryzae physiological strain P6 was chosen as indicator bacteria.The fermentation broth could show obvious bacteriostatic activity when the tempreture was below 80 ℃ or exposured in the 4 000 lx illuminant;the diameter of inhibition zone decreased when the tempreture came up to 90 ℃.The fermentation broth was sensitive to acidity and alkalinity,the activity decreased after treatment. |
