Abstract

The results of a study of chitosan membranes exhibiting enhanced antimicrobial properties are described in this work. It has been shown that a promising approach to imparting antibacterial and antifungal properties to filtration membranes containing chitosan in a water-insoluble base chemical form is their modification with nanocluster silver. Various nanocluster silver preparations have been compared to identify the sample exhibiting the highest antimicrobial activity. Water-resistant chitosan membranes with the addition of various amounts of nanocluster silver from the Argovit preparation have been synthesized and tested for antimicrobial activity against aerobic and anaerobic bacteria and mold and yeast-like fungi. It has been found that the membranes modified with nanocluster silver exhibit high antimicrobial activity and can be used to purify biological products synthesized by membrane methods from pathogenic bacteria and fungi.

具有增强抗菌性能的壳聚糖滤膜的合成与表征

摘要

这项工作描述了具有增强的抗菌性能的壳聚糖膜的研究结果。已经表明，赋予包含水不溶性基础化学形式的壳聚糖的滤膜抗菌和抗真菌特性的一种有前途的方法是用纳米簇银进行修饰。比较了各种纳米簇银制剂，以鉴定出具有最高抗菌活性的样品。已经合成了添加了Argovit制剂中的各种纳米簇银的防水壳聚糖膜，并测试了其对需氧和厌氧细菌以及霉菌和类酵母菌的抗菌活性。
