Abstract:
A new bacterial xylanase belonging to family 5 of glycosyl hydrolases was identified and characterized. The xylanase, Xyn5B from Bacillus sp. strain BP-7, was active on neutral, nonsubstituted xylooligosaccharides, showing a clear difference from other GH5 xylanases characterized to date that show a requirement for methyl-glucuronic acid side chains for catalysis. The enzyme was evaluated on Eucalyptus kraft pulp, showing its effectiveness as a bleaching aid.
