摘要
木文采用固体培养基体外抑菌法，观察了水溶性壳聚糖对细菌生长的影响。结果表明，一定浓度的水溶性壳聚糖对大肠杆菌、金黄色葡萄球菌、枯草杆菌，八叠球菌及放线菌５４０６有不同程度的抑制作用，对以上５种菌株的最小抑制浓度分别为：０．５％、０．３％、０．５％、０．３％、０．５％。实验结果也表明，经高温处理的水溶性壳聚糖的抗菌作用稳定，对即食调味海带具有保鲜防腐的效果。
This paper observed the influence of water-soluble Chitosan on the growth of bacteria cultured in vitro with solid medium. The results showed that Escherichia coli、staphylo- coccus aureus、Bacillus subtillus、Sarcina and Actinomyces5406 could be inhibited to different degrees by Chitosan with certain concertrations. The corresponding MIC Were 0. 5%、0. 3%、 0. 5%、0. 3% and 0. 5%. The results also showed that Chitosan had stable antibacterial action after being treated with heat and it could keep instant flavouring kelp fresh and antiseptic.
