Abstract
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.
