Abstract

Official abstract text for this publication.

The invention further relates to polypeptides encoded by such a nucleic acid molecule, to constructs, vectors and cells comprising the nucleic acid molecule and to a use and method of using a polypeptide of the invention for degrading cellulose.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of degrading any one or more of cellulose, hemicellulose, lichenin and cereal beta-D-glucan or a material comprising cellulose, hemicellulose, lichenin and/or cereal beta-D-glucan, comprising incubating a polypeptide with said cellulose, hemicellulose, lichenin and/or cereal beta-D-glucan or a material comprising cellulose, hemicellulose, lichenin and/or cereal beta-D-glucan, wherein said polypeptide has a cellulase activity, is capable of degrading cellulose to glucose and is thermostable, and said polypeptide comprises: the amino acid sequence set forth in SEQ ID NO. 2, or an amino acid sequence having at least 80% sequence identity to the entirety of SEQ ID NO. 2. 2. The method of claim 1 , wherein said polypeptide comprises an amino acid sequence having at least 95% sequence identity to the entirety of SEQ ID NO. 2. 3. The method of claim 2 , wherein the polypeptide comprises the amino acid sequence set forth in SEQ ID NO. 2. 4. A method of degrading any one or more of cellulose, hemicellulose, lichenin and cereal beta-D-glucan or a material comprising cellulose, hemicellulose, lichenin and/or cereal beta-D-glucan, comprising incubating a polypeptide with said cellulose, hemicellulose, lichenin and/or cereal beta-D-glucan or a material comprising cellulose, hem icellulose, lichenin and/or cereal beta-D-glucan, wherein said polypeptide has a cellulase activity and is thermostable, and said polypeptide comprises the amino acid sequence set forth in SEQ ID NO. 8, or an amino acid sequence having at least 80% sequence identity to the entirety of SEQ ID NO. 8. 5. The method of claim 4 , wherein the polypeptide comprises an amino acid sequence having at least 95% sequence identity to the entirety of SEQ ID NO. 8. 6. The method of claim 5 , wherein the polypeptide comprises the amino acid sequence set forth in SEQ ID NO. 8. 7. The method of claim 5 , wherein the polypeptide comprises the amino acid sequence set forth in SEQ ID NO. 10. 8. The method of claim 5 , wherein the polypeptide comprises the amino acid sequence set forth in SEQ ID NO. 12. 9. The method of claim 1 , wherein the material comprising cellulose, hem icellulose, lichenin and/or cereal beta-D-glucan is lignocellulose. 10. The method of claim 1 , further comprising production of a biofuel. 11. The method of claim 1 , wherein a part of said amino acid sequence having at least 80% sequence identity to the entirety of SEQ ID NO. 2 has at least 90% sequence identity to the entirety of SEQ ID NO. 20. 12. The method of claim 11 , wherein a first part of said amino acid sequence having at least 80% sequence identity to the entirety of SEQ ID NO. 2 has at least 90% sequence identity to the entirety of SEQ ID NO. 18, and a second part of said amino acid sequence having at least 80% sequence identity to the entirety of SEQ ID NO. 2 has at least 90% sequence identity to the entirety of SEQ ID NO. 20. 13. The method of claim 4 , wherein the material comprising cellulose, hemicellulose, lichenin and/or cereal beta-D-glucan is lignocellulose. 14. The method of claim 4 , further comprising production of a biofuel.
