摘要: 海藻酸铜纤维是一种新型的海藻酸盐纤维,为了实现其在医用敷料领域的应用,以大肠杆菌和金黄色葡萄球菌为实验菌株,采用抑菌环和烧瓶振荡法对海藻酸铜纤维的抗菌性能进行了研究和评价,并借助扫描电子显微镜技术对其抗菌机理进行了分析讨论。实验结果表明:海藻酸铜纤维对大肠杆菌和金黄色葡萄球菌具有良好的抗菌性,海藻酸铜纤维对大肠杆菌的抑菌率可达97.4%,对金黄色葡萄球菌的抑菌率可达66.2%;扫描电镜照片表明细菌与海藻酸铜纤维接触后由于铜离子破坏细菌细胞壁使其渗透压改变或阻碍蛋白质的合成使其形态发生了明显变化,影响了细菌正常的新陈代谢,导致细菌裂解死亡。

Abstract: To apply copper alginate fibers in medical as a new alginate fiber, copper alginate fiber was researched and evaluated against Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus), using antibacterial zone and flash shaking method, and analyzed anti-bacterial mechanism by the scanning electron microscopy (SEM). The result showed that copper alginate fibers had antibacterial effects, the antibacterial rate was 97.4% against E.coli, 66.2% against S.aureus; SEM images indicated that bacteria obviously changed after contacting with fibers, the main reason was that copper ion had a damaging effect on pericellular and cell wall. Furthermore, bacterial osmotic pressure was changed and protein synthesis were impeded, and then the normal metabolism of bacteria was destroyed, and finally, bacteria died.
