Microbial production of xylitol from corn cobs using Candida magnoliae was experimentally investigated. Approximately 25 g-xylose/ l solution was obtained from 100 g-corn cobs/ l solution by hydrolysis using 1.0% sulfuric acid at 121°C for 60 min. To remove inhibitors from the hydrolysates, charcoal pellets were found to be effective in selectively removing the inhibitors from the hydrolysates without affecting xylose concentration. C. magnoliae was successfully cultivated using the treated corn cob hydrolysate, resulting in the production of 18.7 g-xylitol/ l from 25 g-xylose/ l within 36 h.
