Biofilm formation is a typical life strategy used by microorganisms populating acidic water systems. The same strategy might be used by microbes in highly acidic soils that are, however, neglected in this regard. In the present study, the microbial community in such highly acidic soil in the Soos National Nature Reserve (Czech Republic) has been investigated using high-throughput DNA sequencing and the organisms associated with biofilm life mode and those preferring planktonic life were distinguished using the biofilm trap technique. Our data show the differences between biofilm and planktonic microbiota fraction, although the majority of the organisms were capable of using both life modes. The by far most abundant prokaryotic genus was Acidiphilium and fungi were identified among the most abundant eukaryotic elements in biofilm formations. On the other hand, small flagellates from diverse taxonomical groups predominated in plankton. The application of cellulose amendment as well as the depth of sampling significantly influenced the composition of the detected microbial community.

捷克共和国苏斯国家自然保护区的高酸性土壤（pH <3）中的生物膜和浮游微生物群落。

生物膜的形成是微生物在酸性水系统中的典型生活策略。微生物可以在高酸性土壤中使用相同的策略，但是在这方面却被忽略了。在本研究中，已经使用高通量DNA测序技术对苏斯国家自然保护区（捷克共和国）这样酸性高的土壤中的微生物群落进行了研究，并利用生物膜区分了与生物膜生命模式相关的生物以及偏爱浮游生物的生物。陷阱技术。我们的数据显示了生物膜和浮游菌群比例之间的差异，尽管大多数生物体都能够使用两种生命模式。迄今为止最丰富的原核生物是嗜酸性生物膜形成中最丰富的真核生物元素被认为是真菌和真菌。另一方面，来自浮游生物的各种生物分类群的小鞭毛占主导地位。纤维素改良剂的应用以及采样深度显着影响了检测到的微生物群落的组成。
