Figure 4From: Phenotypic characterisation of Saccharomyces spp. yeast for tolerance to stresses encountered during fermentation of lignocellulosic residues to produce bioethanol Phenotypic microarray analysis (redox signal intensity) of hybrids. The response of hybrid diploids to stress was compared with the parental stains S. cerevisiae (Y21) and S. cerevisiae (YPS128) (A-E) and S. cerevisiae (Y55) and S. kudriavzevii (IFO1803) (F-I) Metabolic output for S. cerevisiae (Y12), S. cerevisiae (YPS128) and a diploid cross (Y12 × Y128) for (A) control (6% (w/v) glucose at 30°C), (B) 6% glucose and 10% (w/v) sorbitol, (C) 6% glucose and 25 mM acetic acid (D) 6% glucose at 35°C. Metabolic output for S. cerevisiae (Y55) and S. kudriavzevii (IFO1803) and a diploid cross (Y55 × IFO1803) for (E) control (6% (w/v) glucose at 30°C), (F) 6% glucose and 10% (w/v) sorbitol, (G) 6% glucose and 25 mM acetic acid and (H) 6% glucose at 35°C. The data shown is an average of triplicate values with standard deviations shown.Back to article page
