The present invention relates to xylanase variants, polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; compositions comprising the xylanase variants and methods of using the variants.

The application relates to an enzyme composition, a process for the preparation thereof and the use of the enzyme composition in enzymatic hydrolysis.

The present invention relates to xylanase variants, polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; compositions comprising the xylanase variants and methods of using the variants.

The present invention relates to xylanase variants, polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; compositions comprising the xylanase variants and methods of using the variants.

The present invention provides compositions, methods, and kits based on a novel two-enzyme system. This system uses a combination of an appendage dependent endoxylanase and xylobiohydrolase activity to produce xylobiose and xylan-derived oligosaccharides using lignocellulosic biomass material, an enriched xylan fraction thereof, or an extracted, purified xylan material as a starting material.

Improvement of the intestinal health of a monogastric animal by increasing the levels of cecal butyrate levels in situ in said animal by administering a GH30 glucuronoxylan hydrolase-enriched maize-based animal feed is described. Improving the feed conversion ratio of said animal feed is furthermore observed.

A xylanase-containing feed additive for cereal animal feed is described to facilitate degradation of insoluble glucuronoxylan.

The presence of either a calcium source or a carbonate source with GH30 xylanses significantly improves the release of xylan oligomers from maize and other feeds compared to the same xylanases without the calcium or carbonate source. Animal feed and animal feed additives comprising a combination of one or more polypeptides having xylanase activity; and one or more sources of calcium; and/or one or more sources of carbonate, wherein the polypeptide is a GH30 xylanase provide for improved xylan release from feedstuff.
