Transcriptomic response of the yeast Saccharomyces cerevisiae EC1118® during wine alcoholic fermentation under unusual nutrient starvations.

In order to asses yeast EC1118® strain expression changes during wine alcoholic fermentation triggered by various nutrient starvations, this experiment describes the gene expression under micronutrient starvations that lead to yeast cell death (oleic acid starvation, ergosterol starvation, pantothenic acid starvation and nicotinic starvation) or allow the maintenance of yeast viability (nitrogen starvation).为评估葡萄酒酒精发酵过程中不同营养匮乏条件下酵母EC1118®菌株的基因表达变化，本实验针对两类营养匮乏场景展开研究：一类为会引发酵母细胞死亡的微量营养匮乏，包括油酸匮乏、麦角固醇匮乏、泛酸匮乏与烟酸匮乏；另一类为可维持酵母活力的氮匮乏，并对上述条件下的基因表达情况进行了描述。
