Abstract
A Saccharomyces yeast cell, preferably a Saccharomyces cerevisae yeast cell, comprising one or more nucleic acid sequences encoding an enzyme having NADH-dependent nitrate reductase activity and/or one or more nucleic acid sequences encoding an enzyme having NADH-dependent nitrite reductase activity. An anaerobic fermentation process for the production of a fermentation product using such Saccharomyces yeast cell and a fermentation co-product produced.
Claims20
A Saccharomyces yeast cell, comprising one or more nucleic acid sequences encoding an enzyme having NADH-dependent nitrate reductase activity and one or more nucleic acid sequences encoding an enzyme having NADH-dependent nitrite reductase activity;

- 1 or an amino acid sequence having at least 80% sequence identity to SEQ ID NO:
- 1;
- and
- wherein the one or more nucleic acid sequences encoding an enzyme having NADH-dependent nitrite reductase activity encode the amino acid sequence set forth by SEQ ID NO:
- 3 or an amino acid sequence having at least 80% sequence identity to SEQ ID NO:
- 3 and the amino acid sequence set forth by SEQ ID NO:
- 4 or an amino acid sequence having at least 80% sequence identity to SEQ ID NO:
- 4.
