Nutritionally-induced differences in the metabolic profiles of Chlamydomonas reinhardtii and Saccharomyces cerevisae determined by 1H-NMR and cross model validation and permutation testing

Using cross validation, permutation and rank products statistical procedures we identified biomarker regions in proton spectra of polar metabolites extracted from the algae Chlamydomonas reinhardtii (light and dark grown) and from the yeast Saccharomyces cerevisae (aerobically and anaerobically grown).
