| 520 | 3 | |a Candida utilis often encounters an acid stress environment when hexose and pentose are metabolized to produce acidic bio-based materials. In order to reveal the physiological role of glutathione (GSH) in the response of cells of this industrial yeast to acid stress, an efficient GSH-producing strain of C. utilis CCTCC M 209298 and its mutants deficient in GSH biosynthesis, C. utilis Δgsh1 and Δgsh2, were used in this study. A long-term mild acid challenge (pH3.5 for 6h) and a short-term severe acid challenge (pH1.5 for 2h) were conducted at 18h during batch culture of the yeast to generate acid stress conditions. Differences in the physiological performances among the three strains under acid stress were analyzed in terms of GSH biosynthesis and distribution; intracellular pH; activities of γ-glutamylcysteine synthetase, catalase, and superoxide dismutase; intracellular ATP level; and ATP/ADP ratio. The intracellular GSH content of the yeast was found to be correlated with changes in physiological data, and a higher intracellular GSH content led to greater relief of cells to the acid stress, suggesting that GSH may be involved in protecting C. utilis against acid stress. Results presented in this manuscript not only increase our understanding of the impact of GSH on the physiology of C. utilis but also help us to comprehend the mechanism underlying the response to acid stress of eukaryotic microorganisms. | |
