Biochemical characterization, cloning and molecular modeling of a detergent and organic solvent-stable family 11 xylanase from the newly isolated Aspergillus niger US368 strain

► Biochemical characterization of a new purified Aspergillus niger xylanase. ► High optimum temperature, stability at acidic pH and high specific activity. ► Detergent and organic solvent-stable family 11 xylanase. ► High percentages of Ser/Thr residues promote O-glycosylation.
