A novel thermoacidophilic family 10 xylanase from Penicillium pinophilum C1

► A novel endo-β-1,4-xylanase gene (xyn10C1) was cloned from Penicillium pinophilum C1. ► Deduced XYN10C1 shares 49.3% amino acid sequence identity with its closest homolog. ► Recombinant XYN10C1 produced in Pichia pastoris had thermoacidophilic properties. ► The enzyme was strongly resistant to most metal ions and pepsin and trypsin. ► XYN10C1 increased the filtration rate and reduced the viscosity of simulated mash.
