Resumen

This study evaluated d-xylose-assimilating yeasts that are associated with rotting wood from the Galápagos Archipelago, Ecuador, for xylitol production from hemicellulose hydrolysates. A total of 140 yeast strains were isolated. Yeasts related to the clades Yamadazyma, Kazachstania, Kurtzmaniella, Lodderomyces, Metschnikowia and Saturnispora were predominant. In culture assays using sugarcane bagasse hemicellulose hydrolysate, Candida tropicalis CLQCA-24SC-125 showed the highest xylitol production, yield and productivity (27.1 g L⁻¹ xylitol, Y_p/s ^xyl = 0.67 g g⁻¹, Q_p = 0.38 g L⁻¹. A new species of Cyberlindnera, strain CLQCA-24SC-025, was responsible for the second highest xylitol production (24 g L⁻¹, Y_p/s ^xyl = 0.64 g g⁻¹, Q_p = 0.33 g L⁻¹ h⁻¹) on sugarcane hydrolysate. The new xylitol-producing species Cyberlindneragalapagoensis f.a., sp. nov., is proposed to accommodate the strain CLQCA-24SC-025^T (=UFMG-CM-Y517^T; CBS 13997^T). The MycoBank number is MB 812171.
