摘要
采用圆形纸片法,对鼠尾藻脂溶性物质及经柱层析分离得到的不同洗脱组分进行抗食物腐败菌实验.结果表明,鼠尾藻粗脂对大肠杆菌的抑菌圈为1.25mm.乙醇洗脱组分具有较强的抗4种食物腐败菌的活性,其对枯草杆菌、大肠杆菌、金黄色葡萄球菌和假单胞杆菌的抑菌圈分别达到3.0mm,4.0mm,5.0mm,2.5mm.
Using the circle agar disc diffusion method,antimicrobial activities of the Liposoluble compounds and fractions isolated by column chromatography from Sargassum thunbergii（Mcrt.）Okuntze were assayed against food spoilage bacteria.The Results showed that Sargassum thunbergii（Mcrt.）Okuntze Liposoluble compounds inhibition zone against Escherichia coli reached 1.25mm.Ethanol elution fractions showed strong antimicrobial activities against four food spoilage bacteria and the inhibition zone against Bacillus subtilis,Escherichia coli,Staphylococcus aureus and Pseudomonas stutzeri reached 3.0mm,4.0mm,5.0mm,2.5mm respectively.
