Achieving efficient co-expression of endo- β-1,4-xylanase and α-arabinofuranosidase in Trichoderma reesei and application in the production of arabino-xylo-oligosaccharides.

A feasible process for the degradation of psyllium arabinoxylan (AX) to arabino-xylo-oligosaccharides (AXOS) is proposed. A suspension of Trichoderma reesei mycelium suspension, acting on seed husks of psyllium as a carbon source, produced endo-β-1,4-xylanase (xynTR) and α-arabinofuranosidase (abfTR), with enzymatic activity levels of 11.09 ± 0.
