PCT No. PCT/EP95/02299 Sec. 371 Date Feb. 5, 1997 Sec. 102(e) Date Feb. 5, 1997 PCT Filed Jun. 14, 1995 PCT Pub. No. WO95/34662 PCT Pub. Date Dec. 21, 1995The present invention discloses enzymes having xylanase activity. The xylanases are characterized in that they are active at a temperature of 80 DEG C. or higher. The enzymes are obtainable from anaerobic thermophilic bacteria. The enzymes are suited for use in paper and pulp production processes. The invention also describes cloning and expression of genes having xylanase activity obtained from the deposited strains.
