摘要：
The invention relates to a thermostable xylanase selected from xylanase XP1 having a molecular weight of about 22,500, an isoelectric point at around 8.1 and an optimum temperature for reaction of 70.degree. C. or xylanase XP2 having a molecular weight of about 32,000, an isoelectric point at around 8.5 and an optimum temperature for reaction of 80.degree. C., a gene encoding for the thermostable xylanase, a method for producing the xylanase, applications of the xylanase, a bleaching agent containing the xylanase as an active ingredient, a method for bleaching pulp by using the bleaching agent and Bacillus sp. 2113 and Bacillus sp. 208 both having an ability to produce a thermostable xylanase.
