PROJECT SUMMARY
We engineer Saccharomyces cerevisiae for 2G ethanol by improving tolerance to inhibitors in sugarcane lignocellulosic hydrolysates (LCHs). Using adaptive laboratory evolution, QTL mapping, next-generation sequencing, and flow-cytometry assays, we identify and validate the genetic bases of robustness. With the EasyGuide CRISPR/Cas9 platform and in vivo assembly, we build hyper-tolerant yeast chassis ready to receive additional traits—such as pentose metabolism—for high-performance cellulosic ethanol production.
