Optimised fractionation of wheat bran for arabinose biopurification and xylitol fermentation by Ogataea zsoltii within a biorefinery process

•Fractionation of wheat bran is invented to solubilise arabinose and xylose separately.•Ogataea zsoltii is suitable for arabinose biopurification on wheat bran hydrolysate.•Ogataea zsoltii is appropriate for xylitol fermentation on wheat bran hydrolysate.•Biorefinery process to produce arabinose and xylitol from wheat bran is developed.
