Yeast Nitrogen Base without amino acids (YNB w/o AA) is used for selecting yeasts based on amino acid and carbohydrate requirements. In Yeast Nitrogen Base without amino acids, Ammonium sulphate is included as a readily available nitrogen source for nitrogen assimilation. The medium includes all other vitamins, mineral salts and trace elements required for a vigorous growth of yeast cells.

Compared to full Yeast Nitrogen Base medium, Yeast Nitrogen Base without amino acids lacks Histidine, Methionine and Trypthophan. In combination with Drop Out medium supplement mixtures, Yeast Nitrogen Base without Amino acids provides an excellent medium to cultivate and to select auxothophic strains of yeast that requires the addition of essential nutrients like amino acids and/or vitamins.

The addition of a carbon source like glucose, galactose or raffinose is required. Synthetic Dextrose Minimal medium (SD medium) and Synthetic Complete medium (SC medium) are based upon Yeast Nitrogen Base without amino acids and are complemented with glucose, galactose and raffinose as carbon sources.

Yeast, such as Saccharomyces cerevisiae, can efficiently manage nitrogen scarcity by quickly taking up and catabolising amino acids, which allows for the effective utilisation of nitrogen sources and subsequent biosynthesis of essential compounds (Kevvai et al., 2016 – see publications tab). Additionally, yeast nitrogen base without amino acids has been employed in research to induce specific growth conditions, such as filamentous growth, aiding in the investigation of gene expression patterns and cellular responses.

Equipping Saccharomyces cerevisiae with an Additional Redox Cofactor Allows F420-Dependent Bioconversions in Yeast

by Misun Lee and Marco W. Fraaije (2024)

The research paper “Equipping Saccharomyces cerevisiae with an Additional Redox Cofactor Allows F420-Dependent Bioconversions in Yeast” by Misun and Marco W. Fraaije introduces the additional redox cofactor F420 into Saccharomyces cerevisiae to enable F420-dependent bioconversions in yeast (Lee, 2024). This study represents the first instance of F420 synthesis and utilisation for bioconversion in a eukaryotic organism, demonstrating the potential for developing versatile bioconversion platforms. In the research, yeast nitrogen base without amino acids was utilised as a growth medium for Saccharomyces cerevisiae.

This medium, commonly used in laboratory settings, lacks amino acids to control and manipulate the amino acid content available to the yeast, allowing researchers to study specific pathways or effects related to amino acid metabolism (Faou & Tropschug, 2004). By growing the yeast in this defined medium, the researchers could precisely regulate the nutrients available to the yeast cells, providing insights into the impact of the additional redox cofactor on the bioconversion processes within the yeast cells. The introduction of an extra redox cofactor like F420 into Saccharomyces cerevisiae creates new possibilities for bioconversion processes within yeast cells. This addition has the potential to enhance the metabolic capabilities of the yeast, enabling the utilization of F420-dependent enzymes for various redox reactions. The study contributes to expanding the understanding of redox cofactor utilization in eukaryotic organisms and highlights the potential for utilizing F420-dependent enzymes in bioconversion applications.
