ARS molecular biologist Z. Lewis Liu holds a yeast genome microarray, or “gene chip.” Microarrays help Liu and his associates determine which genes, and networks of genes, enable next-generation biorefinery yeasts to tolerate stressful conditions and to efficiently ferment sugars from straw or other biomass to make cellulosic ethanol.
