Industrial antifoam agents impair ethanol fermentation and induce stress responses in yeast cells

In this study, we investigated the impact of industrial antifoam agents on the physiology and transcriptome of the industrial ethanol Saccharomyces cerevisiae strain CAT-1. We showed that under industrial molasses fermentations similar to the ones used for ethanol production in Brazil, antifoam agents had detrimental effects on productivity, viability and lead to increased stress responses in yeast.本研究探究了工业消泡剂对用于工业乙醇生产的酿酒酵母（Saccharomyces cerevisiae）CAT-1菌株的生理特性与转录组的影响。研究表明，在与巴西乙醇生产所用工艺相似的工业糖蜜发酵环境中，消泡剂会对酵母的生产性能与细胞活力产生不利影响，并会增强酵母的应激反应。
