An immobilized bifunctional xylanase on carbon-coated chitosan nanoparticles with a potential application in xylan-rich biomass bioconversion

- Carbon-coated chitosan was prepared by LBL self-assembly approach.
- Bi functional ATXX was immobilized on the carrier via CN covalent bond.
- Immobilized ATXX could be easily recycled and exhibited improved stability.
- Immobilized ATXX released XOs from xylans and wheat bran directly.
