The microbial community of a full-scale, biologically active drinking water filter was surveyed using molecular techniques. Nitrosomonas, Nitrospira, Sphingomonadales, and Rhizobiales dominated the clone libraries. The results elucidate the microbial ecology of biological filters and demonstrate that biological treatment of drinking water should be considered a viable alternative to physicochemical methods.
采用分子技术对大规模、具有生物活性的饮用水过滤器中的微生物群落进行了调查。亚硝化单胞菌、硝化螺旋菌、鞘氨醇单胞菌目和根瘤菌目主导了克隆文库。研究结果阐明了生物过滤器的微生物生态学,并表明生物处理饮用水应该被视为一种可行的替代物理化学方法的选择。
