Spathaspora arborariae has been sequenced because it is one of the few species of budding yeasts that is known to ferment D-xylose (1). It has been previously isolated from rotting wood in both the Atlantic Rainforest and Cerrado ecosystems in Brazil (1).  Its ability to ferment xylose makes it a potentially useful yeast for biofuel production from plant hydrolysates (2). S. arborariae produces a mixture of ethanol and xylitol during xylose fermentation under oxygen-limited conditions (3). A draft genome consisting of 41 scaffolds has been previously assembled using short-read sequencing technology (4), but improved assembly using longer read technology will provide resources for resequencing projects as well as improved assembly of subtelomeric regions of chromosomes.
