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.

摘要: The present invention relates to a DNA sequence obtainable from Aspergillus tubigensis which encodes a polygalacturonase. It also relates to vectors comprising the DNA sequence and to host cells transformed with such vectors. The invention further relates to the expression of the polygalacturonase and its use.
