Polypeptides having xylanase activity and polynucleotides encoding same

A recombinant host cell comprising a polynucleotide encoding a polypeptide having xylanase activity,

• wherein the polynucleotide is operably linked to one or more heterologous control sequences that direct the production of the polypeptide in the recombinant host cell and/or the polynucleotide is heterologous to the recombinant host cell, and
• wherein the polypeptide having xylanase activity is a fragment of SEQ ID NO:
• 73 that has at least 90% sequence identity to the amino acid sequence of SEQ ID NO:
• 73.

A method of producing a polypeptide having xylanase activity, comprising cultivating a recombinant host cell under conditions conducive for production of the polypeptide, wherein the recombinant host cell comprises a polynucleotide encoding the polypeptide,

• wherein the polynucleotide is operably linked to one or more heterologous control sequences that direct the production of the polypeptide in the recombinant host cell and/or the polynucleotide is heterologous to the recombinant host cell,
• wherein the polypeptide having xylanase activity meets at least one of the following criteria:
• a) comprises the amino sequence of SEQ ID NO:
• 73;
• b) comprises an amino acid sequence that has at least 99.0% sequence identity to the amino acid sequence of SEQ ID NO:
• 73;
• c) is a fragment of SEQ ID NO:
• 73 that has at least 90% sequence identity to the amino acid sequence of SEQ ID NO:
• 73, and
• wherein sequence identity is calculated using an EBLOSUM62 substitution matrix, an open gap penalty of 10 and a gap extension penalty of 0.5.
