Title:
NOVEL XYLANASES AND THEIR USE
Document Type and Number:
WIPO Patent Application WO2005087916
Kind Code:
A3
Abstract:
The present invention relates to novel enzymes with xylanolytic activity that belong to the glycoside hydrolase Family 8. The present invention in particular relates to enzymes isolated from bacterial psychrophilic strains that produce xylanases with an amino acid sequence as identified by any of SEQ ID NOs: 4, 6, 8, 10, 12, 14, 16, 35, 21, 23, 25, 27, 29, 31, 33, 37 or a variant thereof. Another aspect of the invention relates to the corresponding genes. These enzymes find many applications and are advantageously used for instance in feed and food applications such as baking. Compared to conventional xylanases, only small amounts of enzymes are needed to obtain a desired effect, such as an increase of the loaf volume and/or an increase in the width of cut on the surface of baked products.
