Interpretive Summary: Brewer’s yeast strains engineered to use the biomass-derived sugar xylose are limited in their ability to uptake and metabolize the sugar. Natural xylose fermenting yeasts have overcome some of these challenges and rapidly consume xylose. In this study, the genome of a xylose fermenting strain of Spathaspora xylofermentans, originally isolated from the Amazon forest, was sequenced. Of the 5,948 predicted genes, several genes for the transport and utilization of xylose were identified. The genetic information from this strain will contribute to advancing technology to produce fuels and chemicals from renewable agricultural products.

Technical Abstract: Here, we report the draft genome sequence of the yeast Spathaspora xylofermentans UFMG-HMD23.3 (CBMAI 1427=CBS 12681), a D-xylose fermenting yeast isolated from the Amazonian forest. The genome consists of 298 contigs, with a total size of 15.1 Mb, including the mitochondrial genome, and 5,948 predicted genes.
