High Glucose Is a Stimulation Signal of the Salt-Tolerant Yeast Zygosaccharomyces rouxii on Thermoadaptive Growth.

ABSTRACT: The salt-tolerant yeast Zygosaccharomyces rouxii is a typical aroma-producing yeast used in food brewing, but its mechanism of high temperature tolerance is still unclear. In this study, the response mechanism of Z. rouxii to glucose under high temperature stress at 40 °C was explored, based on the total synthetic lowest-nutrient medium. The results of the growth curves and scanning electron microscopy showed that high glucose was necessary for Z. rouxii to restore growth under high temperature stress, with the biomass at 300 g/L of glucose (OD_{600, 120h} = 2.44 ± 0.26) being 8.71 times higher than that at 20 g/L (OD_{600, 120h} = 0.28 ± 0.08). The results of the transcriptome analysis, combined with RT-qPCR, showed that the KEGG analysis of differenti
