【中文摘要】 采用杯碟法和纸层析的方法,测定了榆耳发酵液对九种细菌的抑制作用。结果表明:榆耳发酵液对供试细菌均有不同程度的抑菌作用,尤其是对肠炎杆菌的抑制作用较为突出。用乙醇沉淀法除去多糖的榆耳发酵液,对肠炎杆菌、大肠杆菌、绿脓杆菌,金黄色葡萄球菌、炭疽杆菌仍表现出不同程度的抑制作用。用去多糖浓缩五倍的榆耳发酵液通过抗菌素常规的八个溶媒系纸层析显影试验,以肠炎杆菌为敏感菌展层,均未有明显显迹。
【英文摘要】 The inhibitory effects of the fermentation broth of Gloeostereum incarnatum have been determined by using the cup plate method and paper chromatography. The results showed that the broth had inhibitory effects in different degree to every strain of the nine bacteria tested, and there is an especially stronger effection to Salmonella enterilidis. The fermentation broth, whose polysaccharides have been eliminated by using the method of ethanol precipitation, still had inhibitory effects to S. enterilidis, E. coli, P. aeruginos and B. anthracis. The broth, when concentrated by five times, were tested in the conventional eight solvent systems paper chromatography, and S. enterilidis acted as sensitive strain, but the results showed little effects.
