Saccharomyces cerevisiae ascospores germinate in the presence of acetate without any detectable trehalose degradation, as revealed by high-resolution nuclear magnetic resonance spectroscopy and by a standard colorimetric assay. The results presented here substantiate the hypothesis that in S. cerevisiae trehalose supplies energy during dormancy of the spores and not during the germination process.
