This work describes preparation of bacterial cellulose membranes and their use as filters for water remediation. The samples were tested as filters using natural specimens that were extracted from the Igarassu River basin in Pernambuco, Brazil, and using suspensions with a high load of Escherichia coli and raw industrial effluents from the dairy and textile industries. The bacterial cellulose membrane performance was compared with commercial membranes that are used in sterile environments with better results. The membranes were shown to be effective for removing E. coli and dye effluent for up to ten cycles. When the samples that were extracted from the river were studied, no microorganisms were detected after the filtrate was inoculated into a culture medium. The results reported here show that the bacterial cellulose membranes are effective for the remediation of samples with different compositions.

用于环境水修复和工业废水处理的细菌纤维素膜

这项工作描述了细菌纤维素膜的制备及其作为水修复过滤器的用途。使用从巴西伯南布哥州伊加拉苏河流域提取的天然标本，以及高负荷大肠杆菌和乳制品和纺织工业原料工业废水的悬浮液，对样品进行过滤器测试。将细菌纤维素膜的性能与在无菌环境中使用的商业膜进行了比较，结果更好。膜可有效去除大肠杆菌和染料流出物多达十个循环。对从河中提取的样品进行研究时，将滤液接种到培养基中后未检测到微生物。此处报道的结果表明，细菌纤维素膜可有效修复具有不同成分的样品。
