Scheffersomyces coipomoensis (formerly Candida coipomoensis) has been sequenced due to its membership in a genus that contains numerous D-xylose fermenting yeasts, which could lend insight into how this trait has evolved. It was first isolated from decayed wood in southern Chile (1), and has also been subsequently isolated from other habitats, including a high-altitude lake in Patagonia (2). Multi-locus sequence typing has revealed that this species is most closely related to Scheffersomyces queiroziae, a known xylose fermenter (3).
