Xylitol and arabitol are sugar alcohols with similar properties and applications. Although the biotechnological production of xylitol is already being explored, its coproduction with arabitol is still in the early stages. This study aimed to improve the coproduction of xylitol and arabitol by Candida tropicalis from sugarcane bagasse hemicellulosic hydrolysate. The most promising results were achieved with 2.2 g L⁻¹ nitrogen, obtained by mixing 80% yeast hydrolysate and 20% corn steep water. For fermentations conducted in a bioreactor, the concentrations of xylitol (52.1 g L⁻¹) and arabitol (4.2 g L⁻¹) were 65 and 3.7 times higher, respectively, than those reported in the literature for similar processes, with productivities and yields of 0.24 g L⁻¹ h⁻¹ and 0.74 g g⁻¹ for xylitol and 0.02 g L⁻¹ h⁻¹ and 0.43 g g⁻¹ for arabitol. These results show promise for the coproduction of sugar alcohols from sugarcane bagasse hemicellulosic hydrolysate by C tropicalis.

木糖醇和阿拉伯糖醇是具有相似特性和应用的糖醇。虽然木糖醇的生物技术生产已经在探索中，但它与阿拉伯糖醇的联合生产仍处于早期阶段。本研究旨在提高热带假丝酵母从甘蔗渣半纤维素水解液中联合生产木糖醇和阿拉伯糖醇的能力。最有希望的结果是通过混合 80% 的酵母水解产物和 20% 的玉米浸泡水获得的 2.2 g L ⁻¹氮得到的。对于在生物反应器中进行的发酵，木糖醇 (52.1 g L ^-1 ) 和阿拉伯糖醇 (4.2 g L ^-1) 分别比文献中报道的类似工艺高 65 倍和 3.7 倍，木糖醇的生产率和产量分别为 0.24 g L ⁻¹ h ⁻¹和 0.74 g g ^{−1以及 0.02 g L −1} h ⁻¹和阿糖醇为0.43 g g ⁻¹。这些结果显示了通过热带假丝酵母从甘蔗渣半纤维素水解产物联合生产糖醇的前景。
