Abstract: A tool pan has a number of homocentric annular structures which have rubbing zones. Provided between the contiguous rubbing zones is at least a ramp, which is extending along the normal of the tool pan, and the height of which is increased gradually towards the fringe of the tool pan. In a rubbing machine the tool pan is used. The rubbing machine is applicable in paper making industry, and can effectively separate and fibrillate the fiber of herbage by mechanical force between a pair of tool pans, thereby needing not to use chemicals, and according with the modern conception of environmental protection.

Abstract: Modified nucleotide molecules of xylanase and the application of the nucleotide molecules in constructing recombinant vectors, host cells or producing xylanase are disclosed, wherein the nucleotide molecules contain nucleotide sequences having greater than 80% identity with nucleotide sequence shown by SEQ ID NO: 1.

Abstract: A xylanase composition and a method for manufacturing the xylanase composition are provided, wherein the xylanase composition comprises a xylanase and a stabilizer, and the xylanase is from an anaerobic fungus, the stabilizer comprises a polyol, and the content of the polyol is at least 40 wt %, based on the total weight of the xylanase composition.
