At the river Danube, several thermal springs discharge forming spring caves. To reveal and compare the morphological structure and prokaryotic diversity of reddish-brown biofilms developed on the carbonate rock surfaces of the springs, scanning electron microscopy (SEM), and molecular cloning were applied. Microbial networks formed by filamentous bacteria and other cells with mineral crystals embedded in extracellular polymeric substances were observed in the SEM images. Biofilms were dominated by prokaryotes belonging to phyla Proteobacteria, Chloroflexi and Nitrospirae (Bacteria) and Thaumarchaeota (Archaea) but their abundance showed differences according to the type of the host rock, geographic distance, and different water exchange. In addition, representatives of phyla Acidobacteria, Actinobacteria, Caldithrix, Cyanobacteria, Firmicutes Gemmatimonadetes, and several candidate divisions of Bacteria as well as Crenarchaeota and Euryarchaeota were detected in sample-dependent higher abundance. The results indicate that thermophilic, anaerobic sulfur-, sulfate-, nitrate-, and iron(III)-reducing chemoorganotrophic as well as sulfur-, ammonia-, and nitrite-oxidizing chemolithotrophic prokaryotes can interact in the studied biofilms adapted to the unique and extreme circumstances (e.g., aphotic and nearly anoxic conditions, oligotrophy, and radionuclide accumulation) in the thermal karst springs.}, keywords = {SYSTEM; BACTERIA; COMMUNITIES; ARCHAEA; DIVERSITY; WATER; POPULATIONS; INSIGHTS; GEN.

Calcium, Mg, Mn, Fe, and Zn were found to have a quantitative determination frequency larger than 80 % and a concentration greater than 100 μg/g.

The principal component analyses of elemental concentration data followed by the application of general linear models revealed that, for male collared flycatchers, the concentration of Sn, Pb, Ni, Sr, Mg, Zn, Ba, and Sc differed significantly in the wing and tail feathers collected from the same individuals. With females, only the Ca and Sc concentration showed a significant difference between wing and tail feathers. Moreover, the concentration of rare earth elements, V, Fe, Sr, Mg, Mn, Zn, Pb, and Ba in tail feathers allowed differentiation between sexes while the concentration of Se, Bi, and Sc between yearling and adult male individuals.

To compare the prokaryotic communities, reddish-brown cave wall biofilm, black biogeochemical layers, and thermal water samples from the phreatic mixing zone of the cave were subjected to three investigative approaches, scanning electron microscopy, cultivation, and molecular cloning. According to the SEM images, multilayer network structures were observed in the biofilm formed by iron-accumulating filamentous bacteria and mineral crystals. Cultivated strains belonging to Aeromonadaceae and Enterobacteriaceae were characteristic from both water and subaqueous biofilm samples. The most abundant molecular clones were representatives of the phylum Chloroflexi in the reddish-brown biofilm, the class Gammaproteobacteria in the black biogeochemical layer, and Thiobacillus (Betaproteobacteria) in the thermal water samples. The reddish-brown biofilm and black biogeochemical layer’s bacterial communities proved to be somewhat more diverse than that of the thermal water. The archaeal 16S rRNA gene clone libraries were dominated by thermophilic ammonia-oxidizer Nitrosopumilus and Nitrososphaera phylotypes in all three habitats. Considering the metabolic characteristics of known species related to the detected clones, it can be assumed that these communities may participate in the local sulfur and nitrogen cycles and may contribute to microbial mediated sulfuric acid speleogenesis. © 2017, National Speleological Society Inc.

The major outflow point of the waters of the cave system is the Boltív spring, which feeds the artificial Malom Lake. Previous radon measurements in the cave system and in the spring established the highest radon concentration (71 BqL−1) in the springwater. According to previous studies, the origin of radon was identified as iron-hydroxide containing biofilms, which form where there is mixing of cold and thermal waters, and these biofilms efficiently adsorb radium from the thermal water component. Since mixing of waters is responsible for the formation of the cave as well, these iron-hydroxide containing biofilms and the consequent high radon concentrations mark the active cave forming zones. Based on previous radon measurements, it is supposed that the active mixing and cave forming zone has to be close to the spring, since the highest radon concentration was measured there. Therefore radon mapping was carried out with the help of divers in order to get a spatial distribution of radon in the cave passages closest to the spring. Based on our measurements, the highest radon activity concentration (84 BqL−1) was found in the springwater. Based on the distribution of radon activity concentrations, direct connection was established between the spring and the István-room of the cave, which was verified by an artificial tracer. However, the distribution of radon in the cave passages shows lower concentrations (18–46 BqL−1) compared to the spring, therefore an additional deep inflow from hitherto unknown cave passages is assumed, from which waters with high radon content arrive to the spring. These passages are assumed to be in the active cave formation zone. This study proved that radon activity concentration distribution is a useful tool in underwater cave exploration.}, keywords = {SYSTEM; Hungary; Aquifers; radon; Radionuclides; tracer; Mixing; Ventilation; recharge; Buda Thermal Karst; Rn-222; Underwater cave; Hypogenic; GROUNDWATER-FLOW}, year = {2017}, eissn = {1879-1700}, pages = {51-57}, orcid-numbers = {Hegedűs-Csondor, Katalin/0000-0002-3368-9620; Erőss, Anita/0000-0002-2395-3934; Horváth, Ákos/0000-0003-2611-4287} } @article{MTMT:3273962, title = {The effect of reconstruction works on planktonic bacterial diversity of a unique thermal lake revealed by cultivation, molecular cloning and next generation sequencing}, url = {https://m2.mtmt.hu/api/publication/3273962}, author = {Krett, Gergely and Szabó, Attila and Felföldi, Tamás and Márialigeti, Károly and Kériné Borsodi, Andrea}, doi = {10.1007/s00203-017-1379-9}, journal-iso = {ARCH MICROBIOL}, journal = {ARCHIVES OF MICROBIOLOGY}, volume = {199}, unique-id = {3273962}, issn = {0302-8933}, keywords = {GENES; TEMPERATURE; Cultivation; Molecular cloning; POPULATIONS; GRADIENT GEL-ELECTROPHORESIS; SEASONAL DYNAMICS; 16S RIBOSOMAL-RNA; Actinobacteria; pyrosequencing; Anthropogenic disturbance; SP NOV.; FRESH-WATER BACTERIA; BACTERIOPLANKTON COMMUNITY COMPOSITION; Thermal lake; Freshwater bacteria}, year = {2017}, eissn = {1432-072X}, pages = {1077-1089}, orcid-numbers = {Krett, Gergely/0000-0003-1145-4852; Felföldi, Tamás/0000-0003-2009-2478; Márialigeti, Károly/0000-0003-1536-5160; Kériné Borsodi, Andrea/0000-0002-3738-7937} } @article{MTMT:3210431, title = {Soda pans of the Pannonian steppe harbor unique bacterial communities adapted to multiple extreme conditions}, url = {https://m2.mtmt.hu/api/publication/3210431}, author = {Szabó, Attila and Korponai, Kristóf and Kerepesi, Csaba and Somogyi, Boglárka and Vörös, Lajos and Bartha, D and Márialigeti, Károly and Felföldi, Tamás}, doi = {10.1007/s00792-017-0932-4}, journal-iso = {EXTREMOPHILES}, journal = {EXTREMOPHILES : LIFE UNDER EXTREME CONDITIONS}, volume = {21}, unique-id = {3210431}, issn = {1431-0651}, abstract = {Soda pans of the Pannonian steppe are unique environments regarding their physical and chemical characteristics: shallowness, high turbidity, intermittent character, alkaline pH, polyhumic organic carbon concentration, hypertrophic condition, moderately high salinity, sodium and carbonate ion dominance.

The GDRGF concept informs about basin hydraulics and groundwater as a geologic agent. It became obvious that the effect of heterogeneity and anisotropy on the flow pattern could be derived from hydraulic reactions of the aquifer system. The topography and heat as driving forces were examined by numerical simulations of flow and heat transport. Evaluation of groups of springs, in terms of related discharge phenomena and regional chloride distribution, reveals the dominance of topography-driven flow when considering flow and related chemical and temperature patterns. Moreover, heat accumulation beneath the confined part of the system also influences these patterns. The presence of cold, lukewarm and thermal springs and related wetlands, creeks, mineral precipitates, and epigenic and hypogenic caves validates the existence of GDRGF in the system. Vice versa, groups of springs reflect rock–water interaction and advective heat transport and inform about basin hydraulics. Based on these findings, a generalized conceptual GDRGF model is proposed for an unconfined and confined carbonate region. An interface was revealed close to the margin of the unconfined and confined carbonates, determined by the GDRGF and freshwater and basinal fluids involved. The application of this model provides a background to interpret manifestations of flowing groundwater in thick carbonates generally, including porosity enlargement and hydrocarbon and heat accumulation. © 2015, Springer-Verlag Berlin Heidelberg.}, keywords = {Hungary; groundwater flow; Hydraulic properties; Carbonate rocks; Geological agency}, year = {2015}, eissn = {1435-0157}, pages = {1359-1380}, orcid-numbers = {Mádlné Szőnyi, Judit/0000-0002-5628-4386; Tóth, Ádám/0000-0002-7300-6687} } @article{MTMT:2746362, title = {DIVERSITY AND MORPHOLOGICAL STRUCTURE OF BACTERIAL COMMUNITIES INHABITING THE DIANA-HYGIEIA THERMAL SPRING (BUDAPEST, HUNGARY)}, url = {https://m2.mtmt.hu/api/publication/2746362}, author = {Anda, Dóra and Gabriella, Büki and Krett, Gergely and Makk, Judit and Márialigeti, Károly and Erőss, Anita and Mádlné Szőnyi, Judit and Kériné Borsodi, Andrea}, doi = {10.1556/AMicr.61.2014.3.7}, journal-iso = {ACTA MICROBIOL IMMUNOL HUNG}, journal = {ACTA MICROBIOLOGICA ET IMMUNOLOGICA HUNGARICA}, volume = {61}, unique-id = {2746362}, issn = {1217-8950}, year = {2014}, eissn = {1588-2640}, pages = {329-346}, orcid-numbers = {Krett, Gergely/0000-0003-1145-4852; Makk, Judit/0000-0001-5768-7622; Márialigeti, Károly/0000-0003-1536-5160; Erőss, Anita/0000-0002-2395-3934; Mádlné Szőnyi, Judit/0000-0002-5628-4386; Kériné Borsodi, Andrea/0000-0002-3738-7937} } @article{MTMT:2551270, title = {Mössbauer study of biofilms formed at spring caves of Buda Karst, Hungary}, url = {https://m2.mtmt.hu/api/publication/2551270}, author = {Kuzmann, Ernő and Homonnay, Zoltán and Kovács, Krisztina and Zsabka, P and Erőss, Anita and Mádlné Szőnyi, Judit}, doi = {10.1007/s10751-013-0932-4}, journal-iso = {HYPERFINE INTERACT}, journal = {HYPERFINE INTERACTIONS}, volume = {226}, unique-id = {2551270}, issn = {0304-3843}, keywords = {Biofilm; Buda Thermal Karst; 57Fe Mössbauer spectroscopy; Spring caves}, year = {2014}, eissn = {1572-9540}, pages = {571-577}, orcid-numbers = {Kuzmann, Ernő/0000-0002-0183-6649; Homonnay, Zoltán/0000-0001-5299-5394; Kovács, Krisztina/0000-0003-0018-1860; Erőss, Anita/0000-0002-2395-3934; Mádlné Szőnyi, Judit/0000-0002-5628-4386} } @article{MTMT:1898825, title = {Biofilm bacterial communities inhabiting the cave walls of the Buda Thermal Karst System, Hungary}, url = {https://m2.mtmt.hu/api/publication/1898825}, author = {Kériné Borsodi, Andrea and Héder-Knáb, Mónika and Krett, Gergely and Makk, Judit and Márialigeti, Károly and Erőss, Anita and Mádlné Szőnyi, Judit}, doi = {10.1080/01490451.2011.602801}, journal-iso = {GEOMICROBIOL J}, journal = {GEOMICROBIOLOGY JOURNAL}, volume = {29}, unique-id = {1898825}, issn = {0149-0451}, year = {2012}, eissn = {1521-0529}, pages = {611-627}, orcid-numbers = {Kériné Borsodi, Andrea/0000-0002-3738-7937; Krett, Gergely/0000-0003-1145-4852; Makk, Judit/0000-0001-5768-7622; Márialigeti, Károly/0000-0003-1536-5160; Erőss, Anita/0000-0002-2395-3934; Mádlné Szőnyi, Judit/0000-0002-5628-4386} } @article{MTMT:1843789, title = {Radionuclides as natural tracers for the characterization of fluids in regional discharge areas, Buda Thermal Karst, Hungary}, url = {https://m2.mtmt.hu/api/publication/1843789}, author = {Erőss, Anita and Mádlné Szőnyi, Judit and Heinz, Surbeck and Horváth, Ákos and Nico, Goldscheider and Anita, É Csoma}, doi = {10.1016/j.jhydrol.2012.01.031}, journal-iso = {J HYDROL}, journal = {JOURNAL OF HYDROLOGY}, volume = {426-427}, unique-id = {1843789}, issn = {0022-1694}, keywords = {SYSTEM; Uranium; MOBILITY; Geochemistry; radon; Radium; Buda Thermal Karst; EXAMPLE; radioactive isotopes; RA-226; GROUND WATERS; RIO-DE-JANEIRO; Groundwater mixing; Regional discharge area; Karst aquifer}, year = {2012}, eissn = {1879-2707}, pages = {124-137}, orcid-numbers = {Erőss, Anita/0000-0002-2395-3934; Mádlné Szőnyi, Judit/0000-0002-5628-4386; Horváth, Ákos/0000-0003-2611-4287} } @mastersthesis{MTMT:1442838, title = {Characterization of fluids and evaluation of their effects on karst development at the Rózsadomb and Gellért Hill, Buda Thermal Karst, Hungary}, url = {https://m2.mtmt.hu/api/publication/1442838}, author = {Erőss, Anita}, unique-id = {1442838}, year = {2010}, orcid-numbers = {Erőss, Anita/0000-0002-2395-3934} } @article{MTMT:2821686, title = {Radiosensitivity of subterranean bacteria in the Hungarian Upper Permian Siltstone Formation.}, url = {https://m2.mtmt.hu/api/publication/2821686}, author = {Farkas, Gyöngyi and Gazso, LG and Diosi, G}, doi = {10.1016/S0265-931X(01)00130-8}, journal-iso = {J ENVIRON RADIOACTIV}, journal = {JOURNAL OF ENVIRONMENTAL RADIOACTIVITY}, volume = {61}, unique-id = {2821686}, issn = {0265-931X}, abstract = {The main purpose of this work was to study the radioresistance of subterranean aerobic and anaerobic isolates from the Hungarian Upper Permian Siltstone (Aleurolite) Formation, in order to assess the safety of potential sites of future underground repositories for nuclear waste.

The D10 values of the aerobic and anaerobic vegetative isolates were much lower, in the ranges 0.11 0.57 and 0.22-0.40 kGy. respectively. The variability in bacterial radioresistance indicates the biodiversity at this potential disposal site. These results can affect the construction of a future underground repository, since knowledge of the most resistant microorganism may be of importance as concerns calculation of the time required to inactivate the bacteria surrounding the containers.}, keywords = {SURVIVAL; Hungary; Environmental Monitoring; Soil Microbiology; population dynamics; Soil Pollutants, Radioactive/*metabolism; *Radioactive Waste; Bacteria, Anaerobic/isolation & purification/*physiology}, year = {2002}, eissn = {1879-1700}, pages = {233-239} } @article{MTMT:148406, title = {226Ra in geothermal and bottled mineral waters of Hungary}, url = {https://m2.mtmt.hu/api/publication/148406}, author = {Baradács, Eszter and Hunyadi, Ilona and Dezső, Zoltán and Csige, István and Szerbin, P}, doi = {10.1016/S1350-4487(01)00191-3}, journal-iso = {RADIAT MEAS}, journal = {RADIATION MEASUREMENTS}, volume = {34}, unique-id = {148406}, issn = {1350-4487}, year = {2001}, eissn = {1879-0925}, pages = {385-390} }
