Dataset: A quantitative 1H NMR approach for evaluating the metabolic response of Saccharomyces cerevisiae to mild heat stress

In this study, the effect of growth temperature on the yeast (Saccharomyces cerevisiae) metabolome has been analyzed by one-dimensional proton NMR spectroscopy (1H NMR).

Yeast cells were grown either at 30 or 37°C. A non-targeted chemometric evaluation of the spectra was performed in order to detect potential biomarkers. Moreover, an exhaustive assignment for most of the detected NMR signals was carried out, corresponding to 38 identified metabolites. Resonances from these identified metabolites were integrated, and univariate and multivariate data analyses were applied on the matrices of these relative concentrations. Observed changes in metabolite concentrations were consistent with the expected process of temperature acclimation, showing alterations in amino acid cellular pools, nucleotide metabolism and lipid composition.
