Eleven filamentous fungi were screened for xylitol production in batch cultures. Production was generally low under the growth conditions used in this study. Penicillium crustosum presented the highest production, 0.52 g L-1 from 11.50 g L-1 of D-xylose, representing consumption of 76% of the original D-xylose.
