Exogenous Trehalose Assists <i>Zygosaccharomyces rouxii</i> in Resisting High-Temperature Stress Mainly by Activating Genes Rather than Entering Metabolism.

ABSTRACT: Zygosaccharomyces rouxii is a typical aroma-producing yeast in food brewing, but it has low heat resistance and poor proliferation ability at high temperature. Trehalose is generally considered to be a protective agent that helps stable yeast cells resist heat shock stress, but its functional mechanism for yeast cells in the adaptation period under heat stress is unclear. In this study, the physiological metabolism changes, specific gene transcription expression characteristics, and transcriptome differences of Z. rouxii under different carbon sources under high-temperature stress (40 °C) were compared to explore the mechanism of trehalose inducing Z. rouxii to recover and proliferate under high-temperature stress during the adaptation period. The results showed that h
