van Aalst, Aafke C.A. (author), Geraats, Ellen H. (author), Martini, M.L.A. (author), Mans, R. (author), Pronk, J.T. (author)In anaerobic Saccharomyces cerevisiae cultures, NADH (reduced form of nicotinamide adenine dinucleotide)-cofactor balancing by glycerol formation constrains ethanol yields. Introduction of an acetate-to-ethanol reduction pathway based on heterologous acetylating acetaldehyde dehydrogenase (A-ALD) can replace glycerol formation as 'redox-sink'...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
