Since the discovery of this group of toxins, several effects were revealed, such as hepatic changes, carcinoma, failure, and cancer of the liver. In the European Union, there are concentration limits for this group of mycotoxins in food and feed products; thus, these substances are required in their pure forms to prepare reference standards or certified reference materials. In our present work, a liquid–liquid chromatographic method utilizing a toluene/acetic acid/water ternary system was improved. In order to enhance the purification and gain a higher amount of pure AFs in one separation run, a scale-up of the previous separation was carried out. In several scale-up steps—including the determination of the maximum concentration and volume to load on a 250 mL rotor via a loop and via a pump as well, and the quadruplication of the entire separation procedure to a 1000 mL rotor—an efficient scale-up was achieved. Utilizing a 250 mL rotor in an 8-hour workday, altogether approximately 2.2 g of total AFs could be purified with 8.2 liters of solvent, while on a 1000 mL column, approximately 7.8 g AFs could be prepared, utilizing around 31 liters of solvents.}, year = {2023}, eissn = {2072-6651}, orcid-numbers = {Vágvölgyi, Csaba/0000-0003-0009-7773; Szekeres, András/0000-0003-1651-4623} } @mastersthesis{MTMT:34108873, title = {Purification of fungal secondary metabolites by centrifugal partition chromatography [Fonalas gomba eredetű másodlagos metabolitok tisztítása centrifugális megoszlásos kromatográfiával]}, url = {https://m2.mtmt.hu/api/publication/34108873}, author = {Endre, Gábor}, doi = {10.14232/phd.11258}, publisher = {Universití of Szeged}, unique-id = {34108873}, year = {2022} } @article{MTMT:32588053, title = {Determination of indole-3-acetic acid biosynthetic pathways in fungal endophytes}, url = {https://m2.mtmt.hu/api/publication/32588053}, author = {Turbat, Adiyadolgor and Endre, Gábor and Rakk, Dávid and Vágvölgyi, Csaba and Szekeres, András}, journal-iso = {ACTA MICROBIOL IMMUNOL HUNG}, journal = {ACTA MICROBIOLOGICA ET IMMUNOLOGICA HUNGARICA}, volume = {68}, unique-id = {32588053}, issn = {1217-8950}, year = {2021}, eissn = {1588-2640}, pages = {115}, orcid-numbers = {Vágvölgyi, Csaba/0000-0003-0009-7773; Szekeres, András/0000-0003-1651-4623} } @article{MTMT:31914057, title = {Purification of surfactin compounds produced by a Bacillus subtilis strain}, url = {https://m2.mtmt.hu/api/publication/31914057}, author = {Bartal, Attila and Hunkár, Henriett and Endre, Gábor and Vörös, Mónika and Vágvölgyi, Csaba and Szekeres, András}, doi = {10.14232/abs.2020.2.121-128}, journal-iso = {ACTA BIOL SZEGED}, journal = {ACTA BIOLOGICA SZEGEDIENSIS}, volume = {64}, unique-id = {31914057}, issn = {1588-385X}, year = {2020}, eissn = {1588-4082}, pages = {121-128}, orcid-numbers = {Vörös, Mónika/0000-0003-4236-3929; Vágvölgyi, Csaba/0000-0003-0009-7773; Szekeres, András/0000-0003-1651-4623} } @article{MTMT:31677153, title = {Corrigendum: Structural Diversity and Bioactivities of Peptaibol Compounds From the Longibrachiatum Clade of the Filamentous Fungal Genus Trichoderma (Frontiers in Microbiology, (2019), 10, (1434), 10.3389/fmicb.2019.01434)}, url = {https://m2.mtmt.hu/api/publication/31677153}, author = {Marik, Tamás and Tyagi, Chetna and Balázs, Dóra Krisztina and Urbán, Péter and Szepesi, Ágnes and Bakacsy, László and Endre, Gábor and Rakk, Dávid and Szekeres, András and Andersson, M.A. and Salonen, H. and Druzhinina, I.S. and Vágvölgyi, Csaba and Kredics, László}, doi = {10.3389/fmicb.2020.586868}, journal-iso = {FRONT MICROBIOL}, journal = {FRONTIERS IN MICROBIOLOGY}, volume = {11}, unique-id = {31677153}, issn = {1664-302X}, keywords = {Mass spectrometry; ARABIDOPSIS; Antifungal activity; Trichoderma; LONGIBRACHIATUM; PEPTAIBOL; Mammalian cells; brevicelsin}, year = {2020}, eissn = {1664-302X}, orcid-numbers = {Marik, Tamás/0000-0002-0434-5685; Tyagi, Chetna/0000-0001-7067-4770; Bakacsy, László/0000-0003-2593-1795; Szekeres, András/0000-0003-1651-4623; Vágvölgyi, Csaba/0000-0003-0009-7773; Kredics, László/0000-0002-8837-3973} } @CONFERENCE{MTMT:31675162, title = {Potential implementation of liquid-liquid chromatography for preparative purification of ochratoxin A}, url = {https://m2.mtmt.hu/api/publication/31675162}, author = {Hegedüs, Zsófia and Endre, Gábor and Barbara, Borbély and Kata, Fujkin and Vágvölgyi, Csaba and Szekeres, András}, booktitle = {A Magyar Mikrobiológiai Társaság 2020. évi Nagygyűlése és a XIV.
