Processing lignocellulose into ethanol results in the release of inhibitory compounds affecting the following fermentation phase. Ethanol production from lignocellulosic hydrolysates has been widely reported in literature, but only limited research focused on selecting yeasts able to both tolerate inhibitors and ferment sugars with high yield.One hundred and twenty yeast strains, mainly newly isolates belonging to Saccharomyces cerevisiae, were screened for their fermentative abilities in minimal media supplemented with high glucose and/or xylose concentrations. The...
