The suitability of acid- and enzymatically hydrolyzed birch hemicellulose as biotechnical raw material was studied usingCluconobacter oxydans, Fusarium oxysporum, andCandida utilis for production of xylonic acid, ethanol, and SCP, respectively.
The fermentabilities of both hydrolyzates were rather similar and inhibition was evident in all cases at xylose concentrations of 257–30 g/L and higher.
Potential identified fermentation inhibitors were the lignin-derived compounds sinapyl alcohol, coniferyl alcohol, vanillin, and syringaldehyde and the sugar degradation products furfural and 5-hydroxymethyl furfural.
