Expression data from parental and evolved Saccharomyces cerevisiae F12 cells in the presence of insoluble solids at high concentration and lignocellulose-derived inhibitors
Ontology highlight
ABSTRACT: Increasing yeast robustness against biomass-derived inhibitors and insoluble solids is essential for the realization of a bio-based economy. The xylose-fermenting Saccharomyces cereivisiae F12 strain was subjected to an adaptive laboratory evolution experiment in the presence of these stressors. The resulting evolved strain exhibit better fermentation performance in terms of xylose consumption and ethanol yields than the parental strain. The overexpression of genes related to cell wall integrity and the stress response, together with the downregulation of protein synthesis and iron transport and homeostasis were highlighted as the major biological processes responsible for the improved phenotype.
