Nevertheless, our knowledge on biofilm formation in karstic environment is quite incomplete. The present study aimed to examine biofilm development for a year under controlled conditions in quasi-stagnant water of a hydrothermal spring cave located in the Buda Thermal Karst System (Hungary). Using a model system, we investigated how the structure of the biofilm is formed from the water and also how the growth rate of biofilm development takes place in this environment. Besides scanning electron microscopy, next-generation DNA sequencing was used to reveal the characteristic taxa and major shifts in the composition of the bacterial communities. Dynamic temporal changes were observed in the structure of bacterial communities. Bacterial richness and diversity increased during the biofilm formation, and 9-12 weeks were needed for the maturation. Increasing EPS production was also observed from the 9-12 weeks. The biofilm was different from the water that filled the cave pool, in terms of the taxonomic composition and metabolic potential of microorganisms. In these karstic environments, the formation of mature biofilm appears to take place relatively quickly, in a few months.}, keywords = {COMMUNITIES; DATABASE; bacterial; DRIVEN; Budapest; diversity; thermal karst system}, year = {2020}, eissn = {2045-2322}, orcid-numbers = {Makk, Judit/0000-0001-5768-7622; Felföldi, Tamás/0000-0003-2009-2478; Ács, Éva/0000-0003-1774-157X; Mádlné Szőnyi, Judit/0000-0002-5628-4386; Kériné Borsodi, Andrea/0000-0002-3738-7937} } @article{MTMT:31350770, title = {Bacterial Diversity of a High-Altitude Permafrost Thaw Pond Located on Ojos del Salado (Dry Andes, Altiplano-Atacama Region)}, url = {https://m2.mtmt.hu/api/publication/31350770}, author = {Aszalós, Júlia Margit and Szabó, Attila and Megyes, Melinda and Anda, Dóra and Nagy, Balázs and Kériné Borsodi, Andrea}, doi = {10.1089/ast.2018.2012}, journal-iso = {ASTROBIOLOGY}, journal = {ASTROBIOLOGY}, volume = {20}, unique-id = {31350770}, issn = {1531-1074}, year = {2020}, eissn = {1557-8070}, pages = {754-765}, orcid-numbers = {Megyes, Melinda/0000-0002-7178-5883; Kériné Borsodi, Andrea/0000-0002-3738-7937} } @article{MTMT:31180768, title = {Comparison of planktonic and reed biofilm bacteria in different riverine water bodies of river Danube}, url = {https://m2.mtmt.hu/api/publication/31180768}, author = {Kériné Borsodi, Andrea and Anda, Dóra and Krett, Gergely and Megyes, Melinda and Németh, Kitti and Dobosy, Péter and Aszalós, Júlia Margit and Engloner, Attila}, doi = {10.1002/rra.3597}, journal-iso = {RIVER RES APPL}, journal = {RIVER RESEARCH AND APPLICATIONS}, volume = {36}, unique-id = {31180768}, issn = {1535-1459}, year = {2020}, eissn = {1535-1467}, pages = {852-861}, orcid-numbers = {Kériné Borsodi, Andrea/0000-0002-3738-7937; Krett, Gergely/0000-0003-1145-4852; Megyes, Melinda/0000-0002-7178-5883; Engloner, Attila/0000-0001-7394-0448} } @mastersthesis{MTMT:31148187, title = {A Budai Termálkarszt víz és biofilm prokarióta közösségeinek sokfélesége összefüggésben a hipogén karsztosodással}, url = {https://m2.mtmt.hu/api/publication/31148187}, author = {Anda, Dóra}, doi = {10.15476/ELTE.2019.072}, publisher = {Eötvös Loránd University}, unique-id = {31148187}, year = {2019} } @CONFERENCE{MTMT:30710094, title = {Dominance of an unclassified Betaproteobacteria lineage in the spring waters of the Buda Thermal Karst System (Hungary)}, url = {https://m2.mtmt.hu/api/publication/30710094}, author = {Anda, Dóra and Szabó, A and Felföldi, T and Kériné Borsodi, Andrea}, booktitle = {BAGECO 15}, unique-id = {30710094}, year = {2019}, pages = {61-61}, orcid-numbers = {Kériné Borsodi, Andrea/0000-0002-3738-7937} } @article{MTMT:30659191, title = {Deinococcus fonticola sp. nov., isolated from a radioactive thermal spring in Hungary}, url = {https://m2.mtmt.hu/api/publication/30659191}, author = {Makk, Judit and Lange-Enyedi, Nóra and M Tóth, Erika and Anda, Dóra and Szabó, Attila and Felföldi, Tamás and Schumann, Peter and Mádlné Szőnyi, Judit and Kériné Borsodi, Andrea}, doi = {10.1099/ijsem.0.003383}, journal-iso = {INT J SYST EVOL MICR}, journal = {INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY}, volume = {69}, unique-id = {30659191}, issn = {1466-5026}, year = {2019}, eissn = {1466-5034}, pages = {1724-1730}, orcid-numbers = {Makk, Judit/0000-0001-5768-7622; M Tóth, Erika/0000-0001-9048-5758; Felföldi, Tamás/0000-0003-2009-2478; Mádlné Szőnyi, Judit/0000-0002-5628-4386; Kériné Borsodi, Andrea/0000-0002-3738-7937} } @article{MTMT:30634543, title = {In situ experimental study of the formation and physicochemical circumstances of thermal water-related biogeochemical precipitates and calcites}, url = {https://m2.mtmt.hu/api/publication/30634543}, author = {Kovácsné Bodor, Petra and Anda, Dóra and Makk, Judit and Óvári, Mihály and Bihari, Árpád and Braun, Mihály and Futó, István and Mádlné Szőnyi, Judit}, journal-iso = {GEOPHYS RES ABSTR}, journal = {GEOPHYSICAL RESEARCH ABSTRACTS}, volume = {2019}, unique-id = {30634543}, issn = {1029-7006}, year = {2019}, eissn = {1607-7962}, orcid-numbers = {Makk, Judit/0000-0001-5768-7622; Mádlné Szőnyi, Judit/0000-0002-5628-4386} } @article{MTMT:30539729, title = {Radioactive environment adapted bacterial communities constituting the biofilms of hydrothermal spring caves (Budapest, Hungary)}, url = {https://m2.mtmt.hu/api/publication/30539729}, author = {Lange-Enyedi, Nóra and Anda, Dóra and Kériné Borsodi, Andrea and Szabó, Attila and Pál, Sára Eszter and Óvári, Mihály and Márialigeti, Károly and Kovácsné Bodor, Petra and Mádlné Szőnyi, Judit and Makk, Judit}, doi = {10.1016/j.jenvrad.2019.02.010}, journal-iso = {J ENVIRON RADIOACTIV}, journal = {JOURNAL OF ENVIRONMENTAL RADIOACTIVITY}, volume = {203}, unique-id = {30539729}, issn = {0265-931X}, abstract = {The thermal waters of Gellért Hill discharge area of the Buda Thermal Karst System (Hungary) are characterized by high (up to 1000 Bq/L) 222Rn-activity due to the radium-accumulating biogeochemical layers. Samples were taken from these ferruginous and calcareous layers developed on spring cave walls and water surface. Accumulation of potentially toxic metals (e.g. As, Hg, Pb, Sn, Sr, Zn) in the dense extracellular polymeric substance containing bacterial cells and remains was detected by inductively coupled plasma mass spectrometry. The comparison of bacterial phylogenetic diversity of the biofilm samples was performed by high throughput next generation sequencing (NGS). The analysis showed similar sets of mainly unidentified taxa of phyla Chloroflexi, Nitrospirae, Proteobacteria, Planctomycetes; however, large differences were found in their abundance. Cultivation-based method complemented with irradiation assay was performed using 5, 10 and 15 kGy doses of gamma-rays from a 60Co-source to reveal the extreme radiation-resistant bacteria. The phyla Actinobacteria, Firmicutes, Proteobacteria (classes Alpha- Beta- and Gammaproteobacteria), Bacteriodetes and Deinococcus-Thermus were represented among the 452 bacterial strains. The applied irradiation treatments promoted the isolation of 100 different species, involving candidate novel species, as well. The vast majority of the isolates belonged to bacterial taxa previously unknown as radiation-resistant microorganisms. Members of the genera Paracoccus, Marmoricola, Dermacoccus and Kytococcus were identified from the 15 kGy dose irradiated samples. The close relatives of several known radiation-tolerant bacteria were also detected from the biofilm samples, alongside with bacteria capable of detoxification by metal accumulation, adsorption and precipitation in the form of calcium-carbonate which possibly maintain the viability of the habitat. The results suggest the establishment of a unique, extremophilic microbiota in the studied hydrothermal spring caves.}, keywords = {Biofilm; Thermal spring; Toxic metals; High level radioactivity; Radiation-resistant bacteria}, year = {2019}, eissn = {1879-1700}, pages = {8-17}, orcid-numbers = {Kériné Borsodi, Andrea/0000-0002-3738-7937; Márialigeti, Károly/0000-0003-1536-5160; Mádlné Szőnyi, Judit/0000-0002-5628-4386; Makk, Judit/0000-0001-5768-7622} } @misc{MTMT:30723066, title = {Effects of volcanic activity on bacterial communities inhabiting the crater lake of Ojos del Salado}, url = {https://m2.mtmt.hu/api/publication/30723066}, author = {Aszalós, Júlia Margit and Szabó, Attila and Anda, Dóra and Megyes, Melinda and Nagy, Balázs and Kériné Borsodi, Andrea}, unique-id = {30723066}, year = {2018}, orcid-numbers = {Megyes, Melinda/0000-0002-7178-5883; Kériné Borsodi, Andrea/0000-0002-3738-7937} }
