In the period from July 7 to July 11, 2024, the international conference Grapevine Physiology and Biotechnology – OpenGPB 2024 was held in Logrono, La Rioja, Spain. At the conference, we presented the latest research related to the metabolism of non-Saccharomyces isolates under the title:

“Autochthonous non-Saccharomyces extra-cellular metabolism of tryptophan, tyrosine, and phenylalanine,” authored by Ana Boban, Urska Vrhovsek, Andrea Anesi, Vesna Milanović, and Irena Budić-Leto.

Our poster, which showcased the results on aromatic amino acids and their derivatives in samples of must and experimental wine of the Maraština variety, was awarded the best poster presentation at OpenGPB 2024. The indigenous yeasts isolated and identified in this project exhibit diverse metabolism that can contribute to the formation of the secondary aroma of wine. Particularly notable are the species Metschnikowia sinensis/shanxiensis and Hanseniaspora guilliermondii.
