Abstract
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.
Claims20
A composition, comprising i) a GH30 xylanase and ii) one or more sources of calcium and/or carbonate, said one or more sources of calcium and/or carbonate present in an amount sufficient to increase solubilization of arabinoxylan oligomers, as compared to a control composition devoid of said one or more sources of calcium and/or carbonate, as measured by the release of xylan oligomers as evaluated by measuring the florescence of a supernatant with excitation at 320 nm and emission at 440 nm with activity of said GH30 xylanase measured in arabinoxylan hydrolyzing unit, said GH30 xylanase comprising a polypeptide having at least 90% sequence identity to SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3, SEQ ID NO 16, SEQ ID NO 17, SEQ ID NO 18, SEQ ID NO 19, SEQ ID NO 20 and/or SEQ ID NO 21.
