Diversity of the bacterial communities detected in the water and biofdm of the Diana-Hygieia Thermal Spring located in the Buda Themal Karst System Abstract: Keywords: Anda D., Krett G., Büki G., Makk J., Márialigeti K., Erőss A., Mádl-Szönyi J., Borsodi A. The high radon containing Diana-Hygieia thermal spring of the Rudas spa is located in the southern discharge region of the Buda Thermal Karst System. Cultivation based and molecular cloning methods were simultaneously used to reveal the phylogenetic diversity of bacterial communities adapted to this radioactive environment and found in the water and in the biofilm on the rock surfaces. The identification of representative strains was based on partial 16S rDNA sequence analysis. The phyla Actinobacteria, Firmicutes and Proteobacteria were represented by both bacterial strains and molecular clones but phyla Acidobacteria, Chlorobi, Chlorofexi, Gemmatimonadetes, Nitrospirae and Thermotogae only by molecular clones which showed the highest similarity to uncultured clone sequences originating from different environmental sources. The biofilm bacterial community proved to be somewhat more diverse (dominated by Deltaproteobacteria) than that of the water sample (dominated by Betaproteobacteria). The most frequent molecular clones showed the highest similarity to the chemolithotrophic iron (Ill)-reducing, thermophilic nitrite-oxidizing and sulfate-reducing species.
