Abstract

The seasonal dynamics of river biofilm communities in two German rivers, the Elbe and one of its tributaries, the Spittelwasser, were investigated for the first time by using fluorescence in situ hybridization and a standardized biofilm sampling procedure. We show the importance of members of the beta subclass of the class Proteobacteria, which formed the largest single group in the massively polluted Spittelwasser at all times. Clear seasonal peaks of abundance were observed for the planctomycetes and the Cytophaga-Flavobacterium cluster.

摘要

通过使用荧光原位杂交技术和标准化生物膜采样程序,首次对德国两条河流(易北河及其支流施皮特尔瓦瑟河)中河流生物膜群落的季节动态进行了研究。我们展示了变形菌门β亚类成员的重要性,它们在污染严重的施皮特尔瓦瑟河中始终构成最大的单一菌群。浮霉菌门和噬纤维菌-黄杆菌菌群出现了明显的丰度季节性峰值。
