(author), Daran, J.G. (author)Chemically defined media for cultivation of Saccharomyces cerevisiae strains are commonly supplemented with a mixture of multiple Class-B vitamins, whose omission leads to strongly reduced growth rates.

van Aalst, A.C.A. (author), Jansen, Mickel L.A. (author), Mans, R. (author), Pronk, J.T. (author)Background: Anaerobic Saccharomyces cerevisiae cultures require glycerol formation to re-oxidize NADH formed in biosynthetic processes. Introduction of the Calvin-cycle enzymes phosphoribulokinase (PRK) and ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) has been shown to couple re-oxidation of biosynthetic NADH to ethanol...journal article 2023

van Aalst, A.C.A. (author), Mans, R. (author), Pronk, J.T. (author)Background: Saccharomyces cerevisiae is intensively used for industrial ethanol production. Its native fermentation pathway enables a maximum product yield of 2 mol of ethanol per mole of glucose. Based on conservation laws, supply of additional electrons could support even higher ethanol yields. However, this option is disallowed by the...journal article 2022

Ruangpan, L. (author), Vojinovic, Zoran (author)Over recent decades, hydro-meteorological disasters appear to be becoming more intense and frequent. Nature-Based Solutions (NBS) have been introduced to address hydro-meteorological risks as they offer the possibility of working closely with nature.

(author)Biosynthesis of sterols, which are key constituents of canonical eukaryotic membranes, requiresmolecular oxygen. Anaerobic protists and deep-branching anaerobic fungi are the only eukaryotes in which a mechanism for sterol-independent growth has been elucidated.

(author), Pronk, J.T. (author)Background: In most fungi, quinone-dependent Class-II dihydroorotate dehydrogenases (DHODs) are essential for pyrimidine biosynthesis. Coupling of these Class-II DHODHs to mitochondrial respiration makes their in vivo activity dependent on oxygen availability. Saccharomyces cerevisiae and closely related yeast species harbor a cytosolic Class...journal article 2021

(author), Pronk, J.T. (author)Following publication of the original article [1], the authors reported errors in the text of the Results section and in Table 2. It refers to a mutation in a yeast gene as VPS1<sup>I410L</sup> and to the corresponding change in the Vps1 amino-acid sequence as I410L.
