Bioconversion of hemicellulosic sugars into second generation (2G) ethanol plays a pivotal role in the overall success of biorefineries.\nIn this study, ethanol production performance of a novel xylose-fermenting yeast, Scheffersomyces shehatae UFMG-HM 52.2,\nwas evaluated under batch fermentation conditions using sugarcane bagasse (SB) hemicellulosic hydrolysate as carbon source.\nDilute acid hydrolysis of SB was performed to obtain sugarcane bagasse hemicellulosic hydrolysate (SBHH). It was concentrated,\ndetoxified, and supplemented with nutrients in different formulations to prepare the fermentation medium to the yeast evaluation\nperformance. S. shehataeUFMG-HM52.2 (isolated fromBrazilianAtlantic rain forest ecosystem) was used in fermentations carried\nout in Erlenmeyer flasks maintained in a rotator shaker at 30?C and 200 rpmfor 72 h. The use of a fermentation medium composed\nof SBHHsupplemented with 5 g/L ammonium sulfate, 3 g/L yeast extract, and 3 g/L malt extract resulted in 0.38 g/g of ethanol yield\nand 0.19 g L.h of volumetric productivity after 48 h of incubation time.
