Antibacterial activity of glucomannan/chitosan (KGM/CHI) blend films and their irradiation-modified counterparts were tested. The KGM/CHI blend films after irradiation showed good antibacterial effects against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. Antibacterial activity of the blend films increased with the increase of the content of chitosan. After different dose irradiation, there was no obvious change in the antibacterial effects against St. aureus of the blend films, but the antibacterial effects against E. coli and P. aeruginosa increased significantly.
研究了葡甘聚糖/壳聚糖（KGM/CHI）共混膜及其辐照改性膜的抗菌活性。辐照后的 KGM/CHI 共混膜对大肠杆菌、铜绿假单胞菌和金黄色葡萄球菌均表现出良好的抗菌效果。共混膜的抗菌活性随壳聚糖含量的增加而增加。经不同剂量辐照后，共混膜对金黄色葡萄球菌的抗菌效果无明显变化，但对大肠杆菌和铜绿假单胞菌的抗菌效果显著提高。
