Members of this genus were isolated from various aquatic habitats, and our analysis based on global amplicon sequencing data revealed that their relative abundance can reach up to 5–10 % of the bacterioplankton in soda lakes and pans. Although a remarkable fraction of the most frequent genotypes that we identified from continental aquatic habitats is still uncultured, five new alkaliphilic Belliella strains were characterized in detail in this study, which were isolated from three different soda lakes and pans of the Carpathian Basin (Hungary). Cells of all strains were Gram-stain-negative, obligate aerobic, rod-shaped, non-motile and non-spore-forming. The isolates were oxidase- and catalase-positive, red-coloured, but did not contain flexirubin-type pigments; they formed bright red colonies that were circular, smooth and convex. Their major isoprenoid quinone was MK-7 and the predominant fatty acids were iso-C 15 : 0 , iso-C 17 : 0 3-OH and summed feature 3 containing C 16 : 1 ω 6 c and/or C 16 : 1 ω 7 c . The polar lipid profiles contained phosphatidylethanolamine, an unidentified aminophospholipid, an unidentified glycolipid, and several unidentified lipids and aminolipids. Based on whole-genome sequences, the DNA G+C content was 37.0, 37.1 and 37.8 mol % for strains R4-6 T , DMA-N-10a T and U6F3 T , respectively. The distinction of three new species was confirmed by in silico genomic comparison. Orthologous average nucleotide identity (<85.4 %) and digital DNA–DNA hybridization values (<38.9 %) supported phenotypic, chemotaxonomic and 16S rRNA gene sequence data and, therefore, the following three novel species are proposed: Belliella alkalica sp. nov. (represented by strains R4-6 T =DSM 111903 T =JCM 34281 T =UCCCB122 T and S4-10), Belliella calami sp. nov. (DMA-N-10a T =DSM 107340 T =JCM 34280 T =UCCCB121 T ) and Belliella filtrata sp. nov. (U6F3 T =DSM 111904 T =JCM 34282 T =UCCCB123 T and U6F1).

However, little is known about the seasonal dynamics of the bacterial communities inhabiting these lakes and the role of environmental factors that have the main impact on their structure. Therefore, two soda pans were sampled monthly between April 2013 and July 2014 to reveal changes in the planktonic community. By late spring in both years, a sudden shift in the community structure was observed, the previous algae-associated bacterial communities had collapsed, resulting the highest ratio of Actinobacteria within the bacterioplankton (89%, with the dominance of acIII-A1 lineage) ever reported in the literature. Before these peaks, an extremely high abundance (> 10,000 individuum l-1) of microcrustaceans (Moina brachiata and Arctodiaptomus spinosus) was observed. OTU-based statistical approaches showed that in addition to algal blooms and water-level fluctuations, zooplankton densities had the strongest effect on the composition of bacterial communities. In these extreme environments, this implies a surprisingly strong, community-shaping top-down role of microcrustacean grazers.}, year = {2020}, eissn = {2045-2322}, orcid-numbers = {Vajna, Balázs/0000-0002-5604-7997; Horváth, Zsófia/0000-0003-2857-1094; Márialigeti, Károly/0000-0003-1536-5160; Felföldi, Tamás/0000-0003-2009-2478} } @article{MTMT:31432245, title = {Prokaryotic community composition in a great shallow soda lake covered by large reed stands (Neusiedler See/Lake Fertő) as revealed by cultivation- and DNA-based analyses}, url = {https://m2.mtmt.hu/api/publication/31432245}, author = {Szuróczki, Sára and Szabó, Attila and Korponai, Kristóf and Felföldi, Tamás and Somogyi, Boglárka and Márialigeti, Károly and M Tóth, Erika}, doi = {10.1093/femsec/fiaa159}, journal-iso = {FEMS MICROBIOL ECOL}, journal = {FEMS MICROBIOLOGY ECOLOGY}, volume = {96}, unique-id = {31432245}, issn = {0168-6496}, year = {2020}, eissn = {1574-6941}, orcid-numbers = {Felföldi, Tamás/0000-0003-2009-2478; Márialigeti, Károly/0000-0003-1536-5160; M Tóth, Erika/0000-0001-9048-5758} } @article{MTMT:31338247, title = {Relationships Between Chemical Defenses of Common Toad (Bufo bufo) Tadpoles and Bacterial Community Structure of their Natural Aquatic Habitat}, url = {https://m2.mtmt.hu/api/publication/31338247}, author = {Ujszegi, János and Vajna, Balázs and Móricz, Ágnes and Krüzselyi, Dániel and Korponai, Kristóf and Krett, Gergely and Hettyey, Attila}, doi = {10.1007/s10886-020-01184-4}, journal-iso = {J CHEM ECOL}, journal = {JOURNAL OF CHEMICAL ECOLOGY}, volume = {46}, unique-id = {31338247}, issn = {0098-0331}, year = {2020}, eissn = {1573-1561}, pages = {534-543}, orcid-numbers = {Ujszegi, János/0000-0002-6030-0772; Vajna, Balázs/0000-0002-5604-7997; Krüzselyi, Dániel/0000-0003-4749-7010; Krett, Gergely/0000-0003-1145-4852} } @CONFERENCE{MTMT:32382699, title = {Különféle vízinövények hatása a baktériumközösségek szerkezetére, két sekély tavunk példáján}, url = {https://m2.mtmt.hu/api/publication/32382699}, author = {Korponai, Kristóf and Szuróczki, Sára and Szabó, Attila and Szabó-Tugyi, Nóra and Tóth, V and Somogyi, Boglárka and Márialigeti, Károly and Felföldi, Tamás}, booktitle = {LXI.
