Unlike genus Geobacter that is strictly anaerobic, Shewanella can grow under both oxic and anoxic environments and is capable of metabolizing a wider substrate range. In the present study, the use of strain Shewanella baltica 20 in MFC-based biosensor for BOD monitoring is reported. The S. baltica strain 20 was isolated from river sediment in Hungary. The bacterium could form a biofilm, oxidized glucose, and transferred electrons to produce current when they were enriched on the anode in an air cathode microbial fuel cell (MFC). The tested MFC system demonstrated linearity in the current response to glucose from 50 to 300 mg/L. The electrical efficiency was determined from the polarization curve using the method of Varying Circuit Resistance (VCR) with an external load probed from 10 ohm to 220 k ohm. The maximum power production was 1.2 mW/m2 at an external load of 40 k ohm. Studying the effect of external resistors on the MFC performance showed that the MFC reached higher saturation for 500 mg/L of glucose at lower resistances of 100 and 470 ohm, in comparison to 300 mg/L at 1000 ohm. The results show that the response of the MFC can potentially be tuned by adjusting the external load. Our preliminary study suggests that Shewanella baltica strain 20 may be used for online monitoring of BOD (biological oxygen demand) in wastewater.}, keywords = {SYSTEMS; biosensors; Biosensor; wastewater; Microbial fuel cell; Biological oxygen demand (BOD)}, year = {2024}, eissn = {1532-236X} } @{MTMT:34823736, title = {Antimikróbás kezelés}, url = {https://m2.mtmt.hu/api/publication/34823736}, author = {Bátai, István and Kerényi, Mónika}, booktitle = {Súlyos baleseti agysérültek ellátása}, unique-id = {34823736}, year = {2024}, pages = {190-191}, orcid-numbers = {Kerényi, Mónika/0000-0002-5767-9662} } @CONFERENCE{MTMT:34814487, title = {A gesztenyeméz biofilm képződést gátló hatása}, url = {https://m2.mtmt.hu/api/publication/34814487}, author = {Koloh, Regina and Farkas, Ágnes and Balázs, Viktória Lilla and Kocsis, Béla}, booktitle = {Absztraktkötet: XII.

The sample was originated from a mixed feedlot farm in Hungary where sheep and cattle were held together but in separate stalls. Most of the sheep had respiratory signs (coughing and increased respiratory effort) at the time of sampling. Other NPS were not, but additional enteric samples were collected from sheep (n = 27) and cattle (n = 11) of the same farm at that time. The complete/nearly complete genomes of the identified viruses were determined using RT-PCR and Nanopore (MinION-Flonge) / Dye-terminator sequencing techniques. The results of detailed genomic and phylogenetic analyses indicate that the identified picornavirus most likely belongs to a type 4 genotype of species Bovine rhinitis B virus (BRBV-4, OR885914) of genus Aphthovirus, family Picornaviridae while the ovine nidovirus (OvNV, OR885915) - as a novel variant - could belong to the recently created Bovine nidovirus 1 (BoNV) species of genus Bostovirus, family Tobaniviridae. None of the identified viruses were detectable in the enteric samples using RT-PCR and generic screening primer pairs. Both viruses are well-known respiratory pathogens of cattle, but their presence was not demonstrated before in other animals, like sheep. Furthermore, neither BRBV-4 nor BoNVs were investigated in European cattle and/or sheep flocks, therefore it cannot be determined whether the presence of these viruses in sheep was a result of a single host species switch/spillover event or these viruses are circulating in not just cattle but sheep populations as well. Further studies required to investigate the spread of these viruses in Hungarian and European sheep and cattle populations and to identify their pathogenic potential in sheep.}, keywords = {SHEEP; Respiratory disease; Picornavirus; Co-infection; Spillover; nidovirus; Bovine rhinitis B virus}, year = {2024}, eissn = {1567-7257}, orcid-numbers = {Herczeg, Róbert/0000-0002-5903-0082; Reuter, Gábor/0000-0002-5857-4934; Boros, Ákos/0000-0001-5843-4360} } @article{MTMT:34753258, title = {Gram-negative rough mutants used as test bacteria can increase sensitivity of direct bioautography}, url = {https://m2.mtmt.hu/api/publication/34753258}, author = {Balázs, Viktória Lilla and Böszörményi, Andrea and Kocsis, Béla and Horváth, Györgyi}, doi = {10.1007/s00764-024-00293-0}, journal-iso = {J PLANAR CHROMATOGR MOD TLC}, journal = {JPC - JOURNAL OF PLANAR CHROMATOGRAPHY - MODERN TLC}, unique-id = {34753258}, issn = {0933-4173}, abstract = {Currently, the antimicrobial activity of essential oils (EOs) is an outstanding research field due to antibiotic resistance of microorganisms. Thin-layer chromatography‒direct bioautography (TLC‒DB) is an effective, fast method to find components with antimicrobial activity in a mixture of plant compounds, e.g., in EOs. The volatility and hydrophobic characters of EOs require special experimental conditions, and disc diffusion assay is not appropriate to explore the antimicrobial activity of them. The aim of this study was to use “R” mutants, which are more sensitive to synthetic antimicrobial drugs, in DB to increase the sensitivity of this method. Our hypothesis was that these mutants show sensitivity to some EOs (thyme, clove, and peppermint) as well. The chemical composition of our tested EOs was measured with gas chromatography‒mass spectrometry (GC‒MS). The main compounds (39.8% thymol, 78.8% eugenol, and 50.4% menthol) of EOs showed notable antibacterial activity in TLC‒DB. Based on our results, we suggest to use Salmonella minnesota Re595 rough strain as test bacterium in bioautography, because it showed the highest sensitivity to the tested antibiotics (gentamicin and cephalexin) and EOs. Furthermore, this rough mutant could make TLC‒DB more faster, because only 4 h incubation time was enough to detect the inhibition zones of the active compounds used in this study.}, year = {2024}, eissn = {1789-0993}, orcid-numbers = {Böszörményi, Andrea/0000-0003-3982-7059; Horváth, Györgyi/0000-0001-5344-0294} }
