Ice caves in carbonate rocks, however, remain enigmatic environments with limited knowledge of their microbial taxonomic composition. In this study, bacterial and archaeal communities of the Obstans Ice Cave (Carnic Alps, Southern Austria) were analyzed by next-generation amplicon sequencing and by cultivation of bacterial strains at 10 °C and studying their metabolism. The most abundant bacterial taxa were uncultured Burkholderiaceae and Brevundimonas spp. in the drip water, Flavobacterium, Alkanindiges and Polaromonas spp. in the ice, Pseudonocardia, Blastocatella spp., uncultured Pyrinomonadaceae and Sphingomonadaceae in carbonate precipitates, and uncultured Gemmatimonadaceae and Longimicrobiaceae in clastic cave sediments. These taxa are psychrotolerant/psychrophilic and chemoorganotrophic bacteria. On a medium with Mg2+/Ca2+ = 1 at 21 °C and 10 °C, 65% and 35% of the cultivated strains precipitated carbonates, respectively. The first ~ 200 µm-size crystals appeared 2 and 6 weeks after the start of the cultivation experiments at 21 °C and 10 °C, respectively. The crystal structure of these microbially induced carbonate precipitates and their Mg-content are strongly influenced by the Mg2+/Ca2+ ratio of the culture medium. These results suggest that the high diversity of prokaryotic communities detected in cryogenic subsurface environments actively contributes to carbonate precipitation, despite living at the physical limit of the presence of liquid water.}, year = {2024}, eissn = {2045-2322}, orcid-numbers = {Németh, Péter/0000-0001-5592-5877; Kériné Borsodi, Andrea/0000-0002-3738-7937; Makk, Judit/0000-0001-5768-7622} } @CONFERENCE{MTMT:34474922, title = {Geomicrobiological study of modern microbialites in a thermal spring (Köröm, Hungary)}, url = {https://m2.mtmt.hu/api/publication/34474922}, author = {ÁBEL, CSONGOR NÉMETH and NÓRA, TÜNDE LANGE-ENYEDI and M Tóth, Erika and PÉTER, NÉMETH and IVETT, KOVÁCS and PÉTER, DOBOSY and ATTILA, DEMÉNY and Kériné Borsodi, Andrea and Makk, Judit}, booktitle = {Abstracts of the 19th International Congress of the Hungarian Society for Microbiology}, unique-id = {34474922}, year = {2023}, pages = {74}, orcid-numbers = {M Tóth, Erika/0000-0001-9048-5758; Kériné Borsodi, Andrea/0000-0002-3738-7937; Makk, Judit/0000-0001-5768-7622} } @article{MTMT:34431117, title = {Habitat-related variability in the morphological and taxonomic diversity of microbial communities in two Hungarian epigenic karst caves}, url = {https://m2.mtmt.hu/api/publication/34431117}, author = {Lange-Enyedi, Nóra and Kériné Borsodi, Andrea and Németh, Péter and Czuppon, György and Kovács, Ivett and Leél-Őssy, Szabolcs and Dobosy, Péter and Felföldi, Tamás and Demény, Attila and Makk, Judit}, doi = {10.1093/femsec/fiad161}, journal-iso = {FEMS MICROBIOL ECOL}, journal = {FEMS MICROBIOLOGY ECOLOGY}, volume = {99}, unique-id = {34431117}, issn = {0168-6496}, abstract = {The physical and chemical characteristics of the bedrock, along with the geological and hydrological conditions of karst caves may influence the taxonomic and functional diversity of prokaryotes. Most studies so far have focused on microbial communities of caves including only a few samples and have ignored the chemical heterogeneity of different habitat types such as sampling sites, dripping water, carbonate precipitates, cave walls, cave sediment and surface soils connected to the caves. The aim of the present study was to compare the morphology, the composition and physiology of the microbiota in caves with similar environmental parameters (temperature, host rock, elemental and mineral composition of speleothems) but located in different epigenic karst systems. Csodabogyós Cave and Baradla Cave (Hungary) were selected for the analysis of bacterial and archaeal communities using electron microscopy, amplicon sequencing, X-ray diffraction and mass spectroscopic techniques. The microbial communities belonged to the phyla Pseudomonadota, Acidobacteriota, Nitrospirota and Nitrososphaerota, and they showed site-specific variation in composition and diversity. The results indicate that morphological and physiological adaptations provide survival for microorganisms according to the environment. In epigenic karst caves, prokaryotes are prone to increase their adsorption surface, cooperate in biofilms, and implement chemolithoautotrophic growth with different electron-donors and acceptors available in the microhabitats.}, year = {2023}, eissn = {1574-6941}, orcid-numbers = {Kériné Borsodi, Andrea/0000-0002-3738-7937; Németh, Péter/0000-0001-5592-5877; Czuppon, György/0000-0002-7231-6042; Kovács, Ivett/0000-0001-7015-7909; Felföldi, Tamás/0000-0003-2009-2478; Demény, Attila/0000-0003-0522-9018; Makk, Judit/0000-0001-5768-7622} } @CONFERENCE{MTMT:34082836, title = {Detection of crystallinity changes in speleothem calcite and}, url = {https://m2.mtmt.hu/api/publication/34082836}, author = {Demény, Attila and Németh, Péter and Frisia, S and Lange-Enyedi, Nóra and Makk, Judit and Czuppon, György and Surányi, Gergely and Leél-Őssy, Szabolcs}, booktitle = {Climate Change: The Karst Record IX (KR9)}, unique-id = {34082836}, year = {2022}, pages = {191}, orcid-numbers = {Demény, Attila/0000-0003-0522-9018; Németh, Péter/0000-0001-5592-5877; Makk, Judit/0000-0001-5768-7622; Czuppon, György/0000-0002-7231-6042} } @{MTMT:33626168, title = {A sügér szaporodásbiológiaisajátosságai}, url = {https://m2.mtmt.hu/api/publication/33626168}, author = {Müller, Tamás and Braun, Ádám and Hegyi, Árpád and Ivánovics , Bence and Daniel, Zarski and Makk, Judit and Varju-Katona, Milán and Ács, Éva}, booktitle = {A sügér biológiája és tenyésztése}, unique-id = {33626168}, year = {2022}, pages = {81-90}, orcid-numbers = {Makk, Judit/0000-0001-5768-7622} } @{MTMT:32856977, title = {Barlangból kitenyésztett baktériumtörzsek amorf kalcium-karbonát kiválasztásának tanulmányozása}, url = {https://m2.mtmt.hu/api/publication/32856977}, author = {Lange-Enyedi, Nóra and Makk, Judit and Kótai, László and Klébert, Szilvia and Sebestyén, Zoltán and Molnár, Zsombor and Kériné Borsodi, Andrea and Leél-Őssy, Szabolcs and Demény, Attila and Németh, Péter}, booktitle = {A Magyar Mikroszkópos Társaság 2022 Konferenciájának Kivonatkönyve}, unique-id = {32856977}, year = {2022}, pages = {48-49}, orcid-numbers = {Makk, Judit/0000-0001-5768-7622; Klébert, Szilvia/0000-0002-3107-3371; Kériné Borsodi, Andrea/0000-0002-3738-7937} } @article{MTMT:32560409, title = {Calcium Carbonate Precipitating Cultivable Bacteria from Different Speleothems of Karst Caves}, url = {https://m2.mtmt.hu/api/publication/32560409}, author = {Lange-Enyedi, Nóra and Németh, Péter and Kériné Borsodi, Andrea and Halmy, R and Czuppon, György and Kovács, Ivett and Leél-Őssy, Szabolcs and Demény, Attila and Makk, Judit}, doi = {10.1080/01490451.2021.2019857}, journal-iso = {GEOMICROBIOL J}, journal = {GEOMICROBIOLOGY JOURNAL}, volume = {39}, unique-id = {32560409}, issn = {0149-0451}, year = {2022}, eissn = {1521-0529}, pages = {107-122}, orcid-numbers = {Németh, Péter/0000-0001-5592-5877; Kériné Borsodi, Andrea/0000-0002-3738-7937; Czuppon, György/0000-0002-7231-6042; Kovács, Ivett/0000-0001-7015-7909; Demény, Attila/0000-0003-0522-9018; Makk, Judit/0000-0001-5768-7622} } @misc{MTMT:32024222, title = {Egy ausztriai jégbarlang karbonátkiválasztó baktériumai}, url = {https://m2.mtmt.hu/api/publication/32024222}, author = {Lange-Enyedi, Nóra and Németh, Péter and Kériné Borsodi, Andrea and Czuppon, György and Kovács, Ivett and Felföldi, Tamás and Spötl, C and Makk, Judit}, unique-id = {32024222}, year = {2021}, orcid-numbers = {Németh, Péter/0000-0001-5592-5877; Kériné Borsodi, Andrea/0000-0002-3738-7937; Czuppon, György/0000-0002-7231-6042; Kovács, Ivett/0000-0001-7015-7909; Felföldi, Tamás/0000-0003-2009-2478; Makk, Judit/0000-0001-5768-7622} } @{MTMT:31968474, title = {JÉGBARLANGI BAKTÉRIUMOK GEOMIKROBIOLÓGIAI VIZSGÁLATA}, url = {https://m2.mtmt.hu/api/publication/31968474}, author = {Lange-Enyedi, Nóra and Németh, Péter and Kériné Borsodi, Andrea and Czuppon, György and Kovács, Ivett and Felföldi, Tamás and Spötl, C and Makk, Judit}, booktitle = {XVI.
