Improvement of fungal arabinofuranosidase thermal stability by reversible immobilization

► An α-l-arabinofuranosidase GH51 was successfully secreted by Aspergillus nidulans. ► AbfA hydrolyzed arabinoxylan, xylan, debranched arabinan and pnp-arabinofuranoside. ► AbfA was highly stabilized by reversible immobilization onto Sepharose-Q. ► Immobilized AbfA showed a synergistic effect on arabinoxylan hydrolysis.
