River floodplains in the vicinity of metal mines or industrial plants are often subject to flooding with sediments containing heavy metals, which can be harmful to the soil ecosystem. This study aimed to investigate the microbial properties of the soil at a metal-contaminated site and to determine the significant relationships between the biological and chemical properties of the soil. The study site was located near the village of Gyöngyösoroszi, in the Mátra mountain region of northwest Hungary. A phytoremediation experiment was conducted in a metal-polluted floodplain using willow and corn plantations. The soil basal respiration, substrate-induced respiration, soil microbial biomass carbon (MBC), acid phosphatase activities, and soil chemical properties were measured. The soil of the contaminated sites had significantly higher levels of As, Pb, Zn, Cu, Cd, and Ca, whereas the unpolluted sites had significantly higher levels of phosphorus and potassium. The substrate-induced respiration showed a positive correlation with MBC and negative correlations with the metabolic quotient (qCO2). The soil plasticity index and phosphorus showed a positive correlation with MBC, whereas salinity and the presence of Cd, Pb, Zn, As, and Cu showed a negative correlation. Acid phosphomonoesterase activity negatively correlated with the plant-available phosphorus content and MBC, but was positively correlated with the contents of toxic elements, including cadmium, lead, zinc, arsenic, and copper. This study found a significant correlation between the qCO2 and the toxic element content. This suggests that an enhanced metabolic quotient (qCO2), together with a decreased MBC/SOC ratio, could be used to indicate the harmful effect of soil contamination by heavy metals in floodplain soils.}, year = {2024}, eissn = {2077-0472}, orcid-numbers = {Szili Kovács, Tibor/0000-0002-8354-0656; Takács, Tünde Mária/0000-0002-2399-2415} } @article{MTMT:34768902, title = {Response of the metabolic activity and taxonomic composition of bacterial communities to mosaically varying soil salinity and alkalinity}, url = {https://m2.mtmt.hu/api/publication/34768902}, author = {Mucsi, Márton and Kériné Borsodi, Andrea and Megyes, Melinda and Szili Kovács, Tibor}, doi = {10.1038/s41598-024-57430-2}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {14}, unique-id = {34768902}, issn = {2045-2322}, abstract = {Soil salinity and sodicity is a worldwide problem that affects the composition and activity of bacterial communities and results from elevated salt and sodium contents. Depending on the degree of environmental pressure and the combined effect of other factors, haloalkalitolerant and haloalkaliphilic bacterial communities will be selected. These bacteria play a potential role in the maintenance and restoration of salt-affected soils; however, until recently, only a limited number of studies have simultaneously studied the bacterial diversity and activity of saline–sodic soils. Soil samples were collected to analyse and compare the taxonomic composition and metabolic activity of bacteria from four distinct natural plant communities at three soil depths corresponding to a salinity‒sodicity gradient. Bacterial diversity was detected using 16S rRNA gene Illumina MiSeq amplicon sequencing. Community-level physiological profiles (CLPPs) were analysed using the MicroResp™ method. The genus-level bacterial composition and CLPPs differed significantly in soils with different alkaline vegetation. The surface soil samples also significantly differed from the intermediate and deep soil samples. The results showed that the pH, salt content, and Na + content of the soils were the main edaphic factors influencing both bacterial diversity and activity. With salinity and pH, the proportion of the phylum Gemmatimonadota increased, while the proportions of Actinobacteriota and Acidobacteriota decreased.}, year = {2024}, eissn = {2045-2322}, orcid-numbers = {Mucsi, Márton/0000-0001-6226-0607; Kériné Borsodi, Andrea/0000-0002-3738-7937; Megyes, Melinda/0000-0002-7178-5883; Szili Kovács, Tibor/0000-0002-8354-0656} } @article{MTMT:34431713, title = {A talaj katabolikus aktivitás mintázatának elemzése mikrorespirációs (MicroResp™) módszerrel}, url = {https://m2.mtmt.hu/api/publication/34431713}, author = {Szili Kovács, Tibor and Mucsi, Márton and Füzy, Anna and Takács, Tünde Mária and Kériné Borsodi, Andrea}, doi = {10.1556/0088.2023.00153}, journal-iso = {AGROKÉMIA ÉS TALAJTAN}, journal = {AGROKÉMIA ÉS TALAJTAN}, volume = {72}, unique-id = {34431713}, issn = {0002-1873}, abstract = {A talaj mikrobiális közösségének funkcionális diverzitása a talaj ökoszisztéma szolgáltatások jelentős részéhez hozzájárul, sok esetben meghatározó jelentőségű.

A 60-year fertilization experiment with mineral fertilizers, farmyard manure and combined treatments was sampled in two consecutive years in maize ( Zea mays L.) and wheat ( Triticum aestivum L.). Soil chemical properties, plant growth and physiological parameters were measured. The MicroResp TM method was applied to assess the community level physiological profiles (CLPPs) of the rhizosphere soil, and the arbuscular mycorrhizal fungal (AMF) colonization of the roots was determined. Samples were taken in the early vegetative stages, at flowering, and at harvest in both years. The measured parameters were analysed using multifactorial ANOVA to determine treatment effects, crop-dependent differences, and seasonality. PCA analysis was performed on the data matrix to reveal more complex correspondences, and Pearson’s product-moment correlation was used to confirm relationships between some of the measured soil and plant parameters. Fertilization treatments caused long-term changes in some biological parameters such as: MicroResp TM parameters, citrate utilization, total substrate-induced respiration value, and the ratio of utilization of amino acids and sugars. The rate of AMF colonization responded mainly to the plant nutrition status and the plant requirements, suggesting a plant-mediated effect in the case of mycorrhiza. Mineral nitrogen fertilization and soil acidification were found to be the main factors affecting the catabolic activity of soil microbiota, while AMF colonization responded to the balance of plant nutrition.}, year = {2023}, eissn = {1932-6203}, orcid-numbers = {Füzy, Anna/0000-0001-7738-6368; Parádi, István/0000-0003-0825-5000; Kelemen, Bettina/0000-0002-5345-6453; Cseresnyés, Imre/0000-0002-4198-9770; Szili Kovács, Tibor/0000-0002-8354-0656; Takács, Tünde Mária/0000-0002-2399-2415} } @article{MTMT:34038342, title = {Üzenet az Agrokémia és Talajtan 72. évfolyamának olvasóihoz}, url = {https://m2.mtmt.hu/api/publication/34038342}, author = {Szili Kovács, Tibor}, doi = {10.1556/0088.2023.00150}, journal-iso = {AGROKÉMIA ÉS TALAJTAN}, journal = {AGROKÉMIA ÉS TALAJTAN}, volume = {72}, unique-id = {34038342}, issn = {0002-1873}, year = {2023}, eissn = {1588-2713}, pages = {1-2}, orcid-numbers = {Szili Kovács, Tibor/0000-0002-8354-0656} } @article{MTMT:33767371, title = {Advanced Research of Rhizosphere Microbial Activity. editorial}, url = {https://m2.mtmt.hu/api/publication/33767371}, author = {Szili Kovács, Tibor and Takács, Tünde Mária}, doi = {10.3390/agriculture13040911}, journal-iso = {AGRICULTURE-BASEL}, journal = {AGRICULTURE-BASEL}, volume = {13}, unique-id = {33767371}, abstract = {Soils are generally considered a complex and largely unexplored vital “black box” with thousands of microorganism taxa in their networks [...]}, year = {2023}, eissn = {2077-0472}, orcid-numbers = {Szili Kovács, Tibor/0000-0002-8354-0656; Takács, Tünde Mária/0000-0002-2399-2415} } @inproceedings{MTMT:33084517, title = {Impact of floods on soil microbial biomass and activity at a floodplain contaminated by former metal mining}, url = {https://m2.mtmt.hu/api/publication/33084517}, author = {Szili Kovács, Tibor and Takács, Tünde Mária}, booktitle = {Proceedings of VI.
