  • Compositions and methods for treating cellulose containing fabrics using truncated cellulase enzyme compositions
    Patent number: 6294366
    Abstract: Alkalophilic and thermophilic cellulases having high stability to elevated temperatures and pH have been isolated from an organism of unknown species, which most closely resembles those in the Caldicellulosiruptor genus and which has been called by us, Tok7B.1, These cellulases have been cloned and expressed in a recombinant system, so that they can be produced in quantity. These are particularly useful in treating cellulosic materials including cotton-containing fabrics, as detergent additives, and in aqueous compositions. We also provide genomic DNA which can be used in recombinant expression vectors and expression systems to produce enhanced alkali and/or temperature stability properties in cellulases other than those specifically described.

  • Thermostable xylanases
    Patent number: 6083733
    Abstract: 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.
