Abstract
The second-generation ethanol (2G) is derived from lignocellulosic hydrolysates (LCHs). These LCHs carry several toxic substances to Saccharomyces cerevisiae, lowering the fermentation efficiency for 2G ethanol production. However, some S. cerevisiae are naturally resistant to LCH inhibitors. One way to analyze the complex phenotype of LCH-tolerant strains is through the mapping of Quanti…
