摘要:
The present invention discloses enzymes having xylanase considerable activity at a pH of 9.0 and a temperature of 70.degree. C. The enzymes are obtainable from deposited strains which are related to alkaliphilic Bacilli. The enzymes are suited for use in paper and pulp production processes.
摘要:
The present invention discloses enzymes having xylanase activity. The xylanases are characterized in that they are active at a temperature of 80.degree. 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.
