摘要
对弗氏链霉菌S-221所产抗菌物质的抗菌活性进行研究,通过弗氏链霉菌S-221所产抗菌物质对7种细菌和10种植物病原真菌的抗菌活性测定,抗菌活性物质对被检测的大肠杆菌7种细菌最低抑菌质量浓度为:0.098～3.130 mg/L;抗菌活性物质分别对水稻纹枯病等供试10种病原真菌的EC50为0.39～4.83 mg/L和EC90范围为8.17～28.44 mg/L。实验结果显示弗氏链霉菌S-221所产抗菌物质具有广谱和强效的抗菌性,具有较广的应用前景。
To explore the antimicrobial activity of antibacterial substances produced by Streptomyces fradiae var S-221.The antimicrobial activity of antibacterial substances produced by Streptomyces fradiae var S-221 on 7 kinds of bacteria and 10 kinds of plant pathogens was determined.The range of MIC to Escherichia coli at on 7 kinds of bacteria is from 0.098 to 3.130 mg/L,the range of EC50 on 10 kinds of plant pathogens is from 0.39~4.83 mg/L and the range of EC90 on 10 kinds of plant pathogens is from 8.17~28.44 mg/L.The inhibitory action of antibacterial substance produced by Streptomyces fradiae Var S-221 is powerful and the pedigree of antimicrobial is wide.
