| 摘 要： | 以果胶酶为催化剂对柚皮果胶进行了水解,得到不同果胶水解物,探讨水解时间对其抑菌活性的影响;采用两倍稀释法测定了适宜水解的柚皮果胶对大肠杆菌、枯草芽孢杆菌和金黄色葡萄球菌的抗菌作用。结果表明,适度水解的柚皮果胶具有明显的抗菌作用,其对大肠杆菌、枯草芽孢杆菌和金黄色葡萄球菌的最低抑菌质量浓度分别为3.75、7.50和3.75 g.L-1,最低杀菌质量浓度分别为3.75、7.50和7.50 g.L-1。

| Abstract: | Pectin hydrolysates were made from pomelo peel pectin,in which a complex pectinase was used as a catalyst.And their inhibitory effects on Escherichia coli,Bacillus subtilis and Staphylococcus aureus were studied.One hydrolysate with the highest inhibition was obtained.Its antibacterial effects were investigated using double dilution method.The hydrolysate showed a high antibacterial activity.It could inhibit the growth of the bacteria at low concentrations,and its minimum inhibitory concentrations on Escher... |
