The goal of the study was to understand the regulation of the enzymatic steps associated with biomethane biosynthesis by H-2, using metagenomic, pan-genomic, and transcriptomic approaches. Methanogenesis in the autotrophic methanogen M. fervens could be easily "switched off" and "switched on" by H-2/CO2 within about an hour. In contrast, the heterotrophic methanogen M. thermophilum was practically insensitive to the addition of the H-2/CO2 trigger although this methanogen also converted H-2/CO2 to CH4. From practical points of view, the regulatory function of H-2/CO2 suggests that in the power-to-gas (P2G) renewable excess electricity conversion and storage systems, the composition of the biomethane-generating methanogenic community is essential for sustainable operation. In addition to managing the specific hydrogenotrophic methanogenesis biochemistry, H-2/CO2 affected several, apparently unrelated, metabolic pathways. The redox-regulated overall biochemistry and symbiotic relationships in the methanogenic communities should be explored in order to make the P2G technology more efficient.}, keywords = {metabolism; IDENTIFICATION; HYDROGEN; REDUCTION; METHANE; ACETATE; STRAINS; ANAEROBIC-DIGESTION; methanogenesis; Dehydrogenases; Hydrogenotrophic methanogens; Power to gas; THERMOPHILICUM}, year = {2023}, eissn = {1432-0614}, pages = {6315-6324}, orcid-numbers = {Szuhaj, Márk/0000-0001-7160-3173; Kakuk, Balázs/0000-0002-4314-5707; Wirth, Roland/0000-0002-2383-2323; Rákhely, Gábor/0000-0003-2557-3641; Kovács, Kornél Lajos/0000-0002-3926-0497; Bagi, Zoltán/0000-0001-7795-2024} } @article{MTMT:34092103, title = {Machine-Learning-Guided Multi-Omics Investigation of Industrial-Scale Biogas Plants Reveals Inter-Kingdom Interactions and Stability of Methanogens}, url = {https://m2.mtmt.hu/api/publication/34092103}, author = {Wirth, Roland and Bagi, Z and Shetty, Prateek and Szuhaj, M and Cheung, S and Kovács, Kornél Lajos and Maróti, Gergely}, journal-iso = {ACTA MICROBIOL IMMUNOL HUNG}, journal = {ACTA MICROBIOLOGICA ET IMMUNOLOGICA HUNGARICA}, volume = {70}, unique-id = {34092103}, issn = {1217-8950}, year = {2023}, eissn = {1588-2640}, pages = {87-88}, orcid-numbers = {Wirth, Roland/0000-0002-2383-2323; Kovács, Kornél Lajos/0000-0002-3926-0497; Maróti, Gergely/0000-0002-3705-0461} } @article{MTMT:34092101, title = {Comparison of Soil Bacterial Communities Under Different Agricultural Land Uses}, url = {https://m2.mtmt.hu/api/publication/34092101}, author = {Márton, D and Farkas, M and Almalkawi, NM and Maróti, Gergely and Wirth, Roland and Táncsics, A and Szegi, Tamás András and Kriszt, B and Cserháti, M}, journal-iso = {ACTA MICROBIOL IMMUNOL HUNG}, journal = {ACTA MICROBIOLOGICA ET IMMUNOLOGICA HUNGARICA}, volume = {70}, unique-id = {34092101}, issn = {1217-8950}, year = {2023}, eissn = {1588-2640}, pages = {33-33}, orcid-numbers = {Maróti, Gergely/0000-0002-3705-0461; Wirth, Roland/0000-0002-2383-2323; Szegi, Tamás András/0000-0002-9280-617X} } @article{MTMT:34011308, title = {Inter-kingdom interactions and stability of methanogens revealed by machine-learning guided multi-omics analysis of industrial-scale biogas plants}, url = {https://m2.mtmt.hu/api/publication/34011308}, author = {Wirth, Roland and Bagi, Zoltán and Shetty, Prateek and Szuhaj, Márk and Cheung, Teur Teur Sally and Kovács, Kornél Lajos and Maróti, Gergely}, doi = {10.1038/s41396-023-01448-3}, journal-iso = {ISME J}, journal = {ISME JOURNAL}, volume = {17}, unique-id = {34011308}, issn = {1751-7362}, abstract = {Multi-omics analysis is a powerful tool for the detection and study of inter-kingdom interactions, such as those between bacterial and archaeal members of complex biogas-producing microbial communities. In the present study, the microbiomes of three industrial-scale biogas digesters, each fed with different substrates, were analysed using a machine-learning guided genome-centric metagenomics framework complemented with metatranscriptome data. This data permitted us to elucidate the relationship between abundant core methanogenic communities and their syntrophic bacterial partners. In total, we detected 297 high-quality, non-redundant metagenome-assembled genomes (nrMAGs). Moreover, the assembled 16 S rRNA gene profiles of these nrMAGs showed that the phylum Firmicutes possessed the highest copy number, while the representatives of the archaeal domain had the lowest. Further investigation of the three anaerobic microbial communities showed characteristic alterations over time but remained specific to each industrial-scale biogas plant. The relative abundance of various microorganisms as revealed by metagenome data was independent from corresponding metatranscriptome activity data. Archaea showed considerably higher activity than was expected from their abundance. We detected 51 nrMAGs that were present in all three biogas plant microbiomes with different abundances. The core microbiome correlated with the main chemical fermentation parameters, and no individual parameter emerged as a predominant shaper of community composition. Various interspecies H 2 /electron transfer mechanisms were assigned to hydrogenotrophic methanogens in the biogas plants that ran on agricultural biomass and wastewater. Analysis of metatranscriptome data revealed that methanogenesis pathways were the most active of all main metabolic pathways.}, year = {2023}, eissn = {1751-7370}, pages = {1326-1339}, orcid-numbers = {Wirth, Roland/0000-0002-2383-2323; Bagi, Zoltán/0000-0001-7795-2024; Szuhaj, Márk/0000-0001-7160-3173; Cheung, Teur Teur Sally/0009-0007-9541-5231; Kovács, Kornél Lajos/0000-0002-3926-0497; Maróti, Gergely/0000-0002-3705-0461} } @article{MTMT:33656499, title = {Screening for plant growth promoting properties in rizosphere microbial communities of dry Hungarian grasslands}, url = {https://m2.mtmt.hu/api/publication/33656499}, author = {Farkas, Milán and Márton, Dalma and Maróti, Gergely and Wirth, Roland and Malatinszky, Ákos and Neveen, Majdi Almalkawi and Táncsics, András and Kriszt, Balázs and Cserháti, Mátyás}, journal-iso = {ACTA MICROBIOL IMMUNOL HUNG}, journal = {ACTA MICROBIOLOGICA ET IMMUNOLOGICA HUNGARICA}, volume = {70}, unique-id = {33656499}, issn = {1217-8950}, year = {2023}, eissn = {1588-2640}, pages = {15-15}, orcid-numbers = {Maróti, Gergely/0000-0002-3705-0461; Wirth, Roland/0000-0002-2383-2323; Malatinszky, Ákos/0000-0001-6388-9191} } @article{MTMT:33334260, title = {Cold-adapted culturing of the microalga Monoraphidium sp. in thin-layer raceway pond for biomass production}, url = {https://m2.mtmt.hu/api/publication/33334260}, author = {Lakatos, Gergely Ernő and Ranglová, Karolína and Bárcenas-Pérez, Daniela and Grivalský, Tomáš and Manoel, João Câmara and Mylenko, Mykola and Cheel, José and Nyári, József and Wirth, Roland and Kovács, Kornél Lajos and Kopecký, Jiří and Nedbalová, Linda and Masojídek, Jiří}, doi = {10.1016/j.algal.2022.102926}, journal-iso = {ALGAL RES}, journal = {ALGAL RESEARCH-BIOMASS BIOFUELS AND BIOPRODUCTS}, volume = {69}, unique-id = {33334260}, issn = {2211-9264}, abstract = {Three cultivation regimes were tested in cold-adapted cultures of the green microalga Monoraphidium in an outdoor thin-layer raceway pond: cultivation under sunlight; its combination with continuous supplementary illumination; and nitrogen depletion using both light sources.

Field tests, visual inspection, ultrasonic testing, BART testing, SEM-EDS and metagenomic analyses were performed to assess the progress of long-term corrosion and determine the influence of microbes in the corrosion process. High corrosion was linked to sulphate reducing bacteria and potentially to methanogenic archaea in the low-velocity pipeline, while moderate corrosion was linked to non-sulphate reducing bacteria in the higher velocity pipeline. Using historical and literature data available as well as our own test results, an empirical model was developed to predict Maximum Localized Penetration change over time to be applied in the ageing management of cooling water systems. Molecular Microbiological Methods in combination with traditional techniques are useful tools in the ageing management of pipelines.
