(author)Background: Reduction or elimination of by-product formation is of immediate economic relevance in fermentation processes for industrial bioethanol production with the yeast Saccharomyces cerevisiae. Anaerobic cultures of wild-type S. cerevisiae require formation of glycerol to maintain the intracellular NADH/NAD<sup>+</sup> balance....journal article 2018

Papapetridis, I. (author), Verhoeven, M.D. (author), Wiersma, S.J. (author), Goudriaan, M. (author), van Maris, A.J.A. (author), Pronk, J.T. (author)Simultaneous fermentation of glucose and xylose can contribute to improved productivity and robustness of yeast-based processes for bioethanol production from lignocellulosic hydrolysates. This study explores a novel laboratory evolution strategy for identifying mutations that contribute to simultaneous utilisation of these sugars in batch...journal article 2018

Papapetridis, I. (author), van Dijk, M. (author), van Maris, A.J.A. (author), Pronk, J.T. (author)Background: Glycerol, whose formation contributes to cellular redox balancing and osmoregulation in Saccharomyces cerevisiae, is an important by-product of yeast-based bioethanol production. Replacing the glycerol pathway by an engineered pathway for NAD<sup>+</sup>-dependent acetate reduction has been shown to improve ethanol yields and...journal article 2017

(author), Klaassen, P (author), Pronk, J.T. (author)The recent start-up of several full-scale ‘second generation’ ethanol plants marks a major milestone in the development of Saccharomyces cerevisiae strains for fermentation of lignocellulosic hydrolysates of agricultural residues and energy crops. After a discussion of the challenges that these novel industrial contexts impose on yeast strains,...journal article 2017

Papapetridis, I. (author), van Dijk, M. (author), Dobbe, Arthur P A (author), Metz, B. (author), Pronk, J.T. (author), van Maris, A.J.A. (author)Background: Acetic acid, an inhibitor of sugar fermentation by yeast, is invariably present in lignocellulosic hydrolysates which are used or considered as feedstocks for yeast-based bioethanol production. Saccharomyces cerevisiae strains have been constructed, in which anaerobic reduction of acetic acid to ethanol replaces glycerol formation...journal article 2016
