| Associated scholarship(s): | 19/05339-2 - Use of CRISPR / dCas9 and microfluidics to uncover gene interactions related to the conversion of xylose into ethanol by S. cerevisiae industrial strains, BE.EP.MS |
Abstract Over the last few decades, the demand for renewable energy has fueled efforts by research institutions and industries to produce hemicellulosic (or second generation) (E2G) ethanol. However, the economic viability of this process depends on the development of commercial strains of Saccharomyces cerevisiae capable of converting five carbons sugars into ethanol, besides tolerating stresses common to the industrial condition. To achieve these goals, metabolic engineering is necessary and, in this context, yeasts adapted to the industrial conditions - industrial yeasts - are considered appropriate backgrounds because they tolerate different stresses inherent to different processes. Although S. cerevisiae is known as an easy subject for genetic engineering, wild strains are usually diploid or polyploid, and therefore require the development or adaptation of efficient genetic manipulation tools, such as the CRISPR / Cas9 genomic editing system. In this project, the main objective is to evaluate and establish a minimum set of genetic modifications necessary to obtain S. cerevisiae diploid lines capable of satisfactorily converting xylose into ethanol. Thus, the metabolic engineering approach based on the CRISPR / Cas9 system intends to enable the development of lineages for testing and application in the E2G process requiring significantly less time compared to traditional techniques.
