Xylitol production from hybrid poplar wood chips pretreated by the ammonia steeping process


Xylitol production from hybrid poplar wood chips pretreated by the ammonia steeping process



Biotechnology Techniques 11(5): 339-341



DOI: 10.1023/a:1018431714955

Xylitol production from hemicellulosic feedstocks by a Candida sp. was inhibited by various compounds present in untreated hydrolysates. Using a pretreatment of wood chips by the ammonia steeping process, 33.6 g xylitol/L was produced from 50 g xylose/L after 5 h giving a productivity of 5.38 g/Lh and yield of 0.74 g/g. Comparable xylitol productivities were obtained upon treatment of hydrolysate with Amberlite weak base anion exchange resin.
