Significant engineering of Saccharomyces cerevisiae is required to enable consolidated bioprocessing (CBP) of lignocellulose to ethanol. Genome modification in S. cerevisiae has been successful partly due to its efficient homology-directed DNA repair machinery. and CRISPR technology has made multi-gene editing even more accessible. https://www.roneverhart.com/MagnaFlow-2003-2006-Toyota-Corolla-Street-Series-Cat-Back-Performance-Exhaust-System/
