Engineering yeast cell factories is a feasible approach to produce value chemicals from renewable feedstocks. However, during the production process, reprogramming of the internal metabolic pathways of yeast cells and environmental stress always compromises its production performance. Here, we engineered the robust to enhance the production of fatty alcohols by downregulating the expression of target of rapamycin gene and deleting histone deacetylase gene in . The enhanced cellular robustness resulted in the extended chronological lifespan (CLS) through metabolic balance and stress response regulation, thus increasing the production of fatty alcohols by up to 56 %. This strategy may be used as a general strategy for building effective microbial cell factories.
工程化酵母细胞工厂是一种利用可再生原料生产高价值化学品的可行方法。然而,在生产过程中,酵母细胞内部代谢途径的重编程和环境压力总是会损害其生产性能。在此,我们通过下调雷帕霉素靶基因的表达并删除酿酒酵母中的组蛋白脱乙酰酶基因,构建了具有更强耐受性的酵母细胞,以提高脂肪醇的产量。增强的细胞耐受性通过代谢平衡和应激反应调节延长了复制寿命(CLS),从而使脂肪醇产量提高了56%。该策略可作为构建高效微生物细胞工厂的通用策略。
