Abstract

 

Xylanase and sulfuric acid were used to hydrolyze sugar beet pulp for the production of L-arabinose and oligosaccharides. Xylanase was obtained by the solid state fermentation of Thermomyces lanuginosus DSM10635. Xylanase or dilute sulfuric acid hydrolysis was adopted to hydrolyze sugar beet pulp. The hydrolysates were quantitatively identified by high-performance liquid chromatography (HPLC). The content of arabinose was 48.4% in the total monosaccharide of sulfuric acid hydrolysate, whereas, more oligosaccharides were obtained from sugar beet pulp hydrolysate of xylanase. This study has established a new way for arabinose production, as well a potential method for oligosaccharides production.

 

Key words: Xylanase, hydrolysis, sugar beet pulp, L-arabinose, HPLC.
