目的 研究拮抗菌X23 发酵液的抗菌作用.方法 运用琼脂扩散法、试管稀释法测定拮抗菌X23 发酵液对金黄色葡萄球菌、白假丝酵母菌、青枯菌、大肠埃及菌、变形杆菌、伤寒沙门菌、绿脓假单胞菌的抑菌环直径、最低抑菌浓度(MIC)和最低杀菌浓度(MBC).结果 拮抗菌X23 发酵液原液对金黄色葡萄球菌、大肠埃及菌抑菌环直径显著＞ 1:4 稀释液的抑菌环直径(P＜0.01);拮抗菌X23 发酵液对金黄色葡萄球菌、白假丝酵母菌、青枯菌、大肠埃及菌、伤寒沙门菌MIC 均为蛋白3.75μg/mL,对大肠埃及菌MIC 为蛋白7.50μg/mL,对金黄色葡萄球菌、白假丝酵母菌、青枯菌、大肠埃及菌的MBC 均为7.50μg/mL.在试验所检测的6个浓...

Objective Study on the antibacterial effect of antagonistic bacterium X23 fermentation liquid.Methods The agar diffusion test and tube dilution method were used for examination of the antibacterial effect of antagonistic bacterium X23 fermentation liquid on S.aureus,Candida albicans,Ralstonia solanacearum,E.coli,Bacillus proteus,Eberthella typhi and Bacillus aeruginosus.Results Compared with 1∶4 diluent,the diameters of inhibition zones formed in original solution against S.aureus and E.coli were remarkably larger（P0.01）;the values of antago...
