The present work strives to develop and optimize the preparation of the HIP complex of the antimicrobial enzyme lysozyme (LYZ) with the ion-pairing agent (IPA) sodium dodecyl sulphate (SDS) relying on the quality-by-design (QbD) approach. The quality target product profile (QTPP) includes the achievement of maximal lipophilicity in a reversible manner to enable the maintenance of biological activity. The related critical quality attributes (CQAs) were defined as complexation efficacy, complex stability, enzyme recovery and activity. Three risk assessment (RA) tools were used to identify and rank the critical process parameters (CPPs) and critical material attributes (CMAs). From this assessment, the pH of the medium, LYZ:SDS molar ratio and drying conditions were determined as high-risk factors that need to be investigated. To the best of our knowledge, for the first time, electrostatic titration was used as a smart approach to determine the optimum molar ratio at different pH values. Based on the predefined CQAs, pH 8 with an LYZ/SDS molar ratio of 1:8 was found to be the optimal condition for complexation efficiency and recovery (%) of a biologically active enzyme. A cost-effective drying process based on a ventilated oven was developed, which resulted in complex qualities comparable to those obtained by the commonly used freeze-drying method. In a nutshell, the optimum conditions for the preparation of the LYZ/SDS HIP complex were efficiently facilitated by the rational application of QbD principles and the utilization of efficient electrostatic titration and ventilated oven-drying methods.}, year = {2024}, eissn = {1999-4923}, pages = {589}, orcid-numbers = {Sovány, Tamás/0000-0003-3392-7788; Varga, Viktória/0000-0001-9933-7604; Csapó, Edit/0000-0002-6980-9524; Regdon, Géza (ifj.)/0000-0002-6921-3069; Pannonhalminé Csóka, Ildikó/0000-0003-0807-2781} } @article{MTMT:34830186, title = {Mass tourism generated urban land expansion in the catchment of Lake Balaton, Hungary – analysis of long-term changes in characteristic socio-political periods}, url = {https://m2.mtmt.hu/api/publication/34830186}, author = {Petrovszki, Judit and Szilassi, Péter and Erős, Tibor}, doi = {10.1016/j.landusepol.2024.107185}, journal-iso = {LAND USE POLICY}, journal = {LAND USE POLICY}, volume = {142}, unique-id = {34830186}, issn = {0264-8377}, year = {2024}, eissn = {1873-5754}, pages = {107185}, orcid-numbers = {Szilassi, Péter/0000-0003-0051-6739} } @article{MTMT:34826023, title = {Electrochemical carbon monoxide reduction at high current density: Cell configuration matters}, url = {https://m2.mtmt.hu/api/publication/34826023}, author = {Monis Ayyub, Mohd and Kormányos, Attila and Endrődi, Balázs and Janáky, Csaba}, doi = {10.1016/j.cej.2024.151698}, journal-iso = {CHEM ENG J}, journal = {CHEMICAL ENGINEERING JOURNAL}, volume = {online}, unique-id = {34826023}, issn = {1385-8947}, year = {2024}, eissn = {1873-3212}, pages = {151698}, orcid-numbers = {Endrődi, Balázs/0000-0003-3237-9222; Janáky, Csaba/0000-0001-5965-5173} } @article{MTMT:34825908, title = {Paired photoelectrochemical conversion of CO2/H2O and glycerol at high rate}, url = {https://m2.mtmt.hu/api/publication/34825908}, author = {Balog, Ádám and Kecsenovity, Egon and Samu, Gergely Ferenc and He, Jie and Fekete, Dávid and Janáky, Csaba}, doi = {10.1038/s41929-024-01134-3}, journal-iso = {NAT CATAL}, journal = {NATURE CATALYSIS}, unique-id = {34825908}, issn = {2520-1158}, abstract = {Photoelectrochemistry holds the promise of directly converting sunlight to valuable chemical products. Photoelectrochemical (PEC) methods, however, lag behind their electrochemical counterparts in terms of current density. In this work, we demonstrate that, by using concentrated sunlight, we can achieve current densities similar to electrochemical methods, but with lower energy input. Specifically, we combined the direct PEC oxidation of glycerol with the dark hydrogen evolution or CO 2 reduction in a membrane-separated continuous-flow PEC cell. We achieved over 110 mA cm −2 photocurrent density, which is at least an order of magnitude larger than those typically reported in the literature. We demonstrated that the product distribution of glycerol oxidation is notably different in PEC and electrochemical scenarios at the same current density, and the parasitic oxygen evolution reaction can be suppressed in the PEC case. This approach raises opportunities to drive complex electrochemical reactions in a more selective manner.}, year = {2024}, eissn = {2520-1158}, orcid-numbers = {Samu, Gergely Ferenc/0000-0002-3239-9154; Janáky, Csaba/0000-0001-5965-5173} } @{MTMT:34825686, title = {Revealing secondary metabolite alterations in fungal endophyte secretom}, url = {https://m2.mtmt.hu/api/publication/34825686}, author = {Kitti, Tari and Turbat, Adiyadolgor and Enkh-Amgalan, Jigjiddorj and Varga, Mónika and Vágvölgyi, Csaba and Szekeres, András}, booktitle = {21st Wellmann International Scientific Conference}, unique-id = {34825686}, year = {2024}, pages = {118}, orcid-numbers = {Vágvölgyi, Csaba/0000-0003-0009-7773; Szekeres, András/0000-0003-1651-4623} } @{MTMT:34825669, title = {Analysis of surfactin components produced by Bacillus strains isolated from environmental samples}, url = {https://m2.mtmt.hu/api/publication/34825669}, author = {Dániel, Hercegfalvi and Varga, Mónika and Allaga, Henrietta and Kredics, László and Vágvölgyi, Csaba and Szekeres, András}, booktitle = {21st Wellmann International Scientific Conference}, unique-id = {34825669}, year = {2024}, pages = {111}, orcid-numbers = {Kredics, László/0000-0002-8837-3973; Vágvölgyi, Csaba/0000-0003-0009-7773; Szekeres, András/0000-0003-1651-4623} } @{MTMT:34825666, title = {Investigation of the metabolomic profile of Pseudomonas strains}, url = {https://m2.mtmt.hu/api/publication/34825666}, author = {Papp, Dóra Anna and Kitti, Tari and Kozma-Bognárné Hamari, Zsuzsanna and Szekeres, András and Vágvölgyi, Csaba and Varga, Mónika}, booktitle = {21st Wellmann International Scientific Conference}, unique-id = {34825666}, year = {2024}, pages = {60}, orcid-numbers = {Kozma-Bognárné Hamari, Zsuzsanna/0000-0001-6374-5083; Szekeres, András/0000-0003-1651-4623; Vágvölgyi, Csaba/0000-0003-0009-7773} } @article{MTMT:34823504, title = {Stable Operation of Paired CO2 Reduction/Glycerol Oxidation at High Current Density}, url = {https://m2.mtmt.hu/api/publication/34823504}, author = {Kormányos, Attila and Szirmai, Adrienn and Endrődi, Balázs and Janáky, Csaba}, doi = {10.1021/acscatal.3c05952}, journal-iso = {ACS CATAL}, journal = {ACS CATALYSIS}, unique-id = {34823504}, issn = {2155-5435}, year = {2024}, eissn = {2155-5435}, orcid-numbers = {Endrődi, Balázs/0000-0003-3237-9222; Janáky, Csaba/0000-0001-5965-5173} } @article{MTMT:34823133, title = {Enhanced Photocatalytic and Filtration Performance of TiO2-Ag Composite-Coated Membrane Used for the Separation of Oil Emulsions}, url = {https://m2.mtmt.hu/api/publication/34823133}, author = {Fazekas, Ákos Ferenc and Gyulavári, Tamás and Ágoston, Áron and Janovák, László and Heszlerné Kopniczky, Judit and László, Zsuzsanna and Veréb, Gábor}, doi = {10.3390/separations11040112}, journal-iso = {SEPARATIONS}, journal = {SEPARATIONS}, volume = {11}, unique-id = {34823133}, issn = {2297-8739}, abstract = {Polyvinylidene fluoride (PVDF) membranes were coated with TiO2 and TiO2-Ag to enhance their efficiency for oil-in-water emulsion separation. The photocatalytic activities of the two modified membranes and their filtration performances were compared in detail. The significantly enhanced photocatalytic activity of the TiO2-Ag composite was proved using a methyl orange (MO) solution (c = 10−5 M) and a crude oil emulsion (c = 50 mg·L−1). The TiO2-Ag-coated membrane reduced the MO concentration by 87%, whereas the TiO2-modified membrane reached only a 46% decomposition. The photocatalytic reduction in the chemical oxygen demand of the emulsion was also ~50% higher using the TiO2-Ag-coated membrane compared to that of the TiO2-coated membrane. The photoluminescence measurements demonstrated a reduced electron/hole recombination, achieved by the Ag nanoparticle addition (TiO2-Ag), which also explained the enhanced photocatalytic activity. A significant improvement in the oil separation performance with the TiO2-Ag-coated membrane was also demonstrated: a substantial increase in the flux and flux recovery ratio (up to 92.4%) was achieved, together with a notable reduction in the flux decay ratio and the irreversible filtration resistance. Furthermore, the purification efficiency was also enhanced (achieving 98.5% and 99.9% COD and turbidity reductions, respectively). Contact angle, zeta potential, scanning electron microscopy (SEM), and atomic force microscopy (AFM) measurements were carried out to explain the results. SEM and AFM images revealed that on the TiO2-Ag-coated membrane, a less aggregated, more continuous, homogeneous, and smoother nanolayer was formed due to the ~50% more negative zeta potential of the TiO2-Ag nanocomposite compared to that of the TiO2. In summary, via Ag addition, a sufficiently hydrophilic, beneficially negatively charged, and homogeneous TiO2-Ag-coated PVDF membrane surface was achieved, which resulted in the presented advantageous filtration properties beyond the photocatalytic activity enhancement.}, year = {2024}, eissn = {2297-8739}, pages = {112}, orcid-numbers = {Gyulavári, Tamás/0000-0001-6103-6689; Janovák, László/0000-0002-2066-319X; Veréb, Gábor/0000-0001-9642-1851} }
