研究了通过美拉德反应制备的水溶性壳聚糖衍生物对金黄色葡萄球菌、单核细胞增生李斯特菌、蜡样芽孢杆菌、大肠杆菌、志贺氏菌和鼠伤寒沙门氏菌的抗菌活性。与酸溶性壳聚糖相比，壳聚糖-葡糖胺衍生物对各种微生物具有相对较高的抗菌活性。此外，发现测试生物体对水溶性壳聚糖衍生物的敏感性在去离子水中比在盐水溶液中更高。金属离子也会降低水溶性壳聚糖衍生物对沙门氏菌的抗菌活性。金黄色。S细胞上清中葡萄糖水平、蛋白质含量和乳酸脱氢酶（LDH）活性明显增加。金黄色葡萄球菌暴露于去离子水中的水溶性壳聚糖衍生物。结果表明，通过Maillard反应制备的水溶性壳聚糖有可能成为酸溶性壳聚糖的一种很有前途的商业替代品。
The antibacterial activity of water-soluble chitosan derivatives prepared by Maillard reactions against Staphylococcus aureus, Listeria monocytogenes, Bacillus cereus, Escherichia coli, Shigella dysenteriae, and Salmonella typhimurium was examined. Relatively high antibacterial activity against various microorganisms was noted for the chitosan-glucosamine derivative as compared to the acid-soluble chitosan. In addition, it was found that the susceptibility of the test organisms to the water-soluble chitosan derivative was higher in deionized water than in saline solution. Metal ions were also found to reduce the antibacterial activity of the water-soluble chitosan derivative on S. aureus. The marked increase in glucose level, protein content and lactate dehydrogenase (LDH) activity was observed in the cell supernatant of S. aureus exposed to the water-soluble chitosan derivative in deionized water. The results suggest that the water-soluble chitosan produced by Maillard reaction may be a promising commercial substitute for acid-soluble chitosan.
