During the acid hydrolysis, some byproducts were generated, such as acetic acid, furfural and low molecular weight phenols, which inhibit bioconversion of xylose to xylitol. Except for acetic acid, these inhibitors were successfully removed from the hydrolyzate by contacting with a steam-activated charcoal (25 g dm-3 dose) for 1 h. Bioconversion of the detoxified hydrolyzate to xylitol by the yeast Candida magnoliae was investigated under the microaerobic conditions. The oxygen transfer rate (OTR) varied from 12.6 to 15.1 mmol-O2 dm-3 h-1. The best fermentative performance of C. magnoliae in the culm hydrolyzate of S. senanensis (xylitol yield of 0.55?0.60 g-xylitol g-xylose-1 and volumetric productivity of 0.82 g dm-3h-1) was obtained at the OTR ranging 14.1?15.1 mmol-O2 dm-3 h-1.}, pages = {807--812}, title = {Bioconversion of bamboo grass culm hydrolyzate into xylitol by yeast Candida magnoliae}, volume = {49}, year = {2015} }
