HOST CELL CAPABLE OF PRODUCING ENZYMES USEFUL FOR DEGRADATION OF LIGNOCELLULOSIC MATERIAL

摘要

The invention relates to a host cell comprising at least four different heterologous polynucleotides chosen from the group of polynucleotides encoding cellulases, hemicellulases and pectinases, wherein the host cell is capable of producing the at least four different enzymes chosen from the group of cellulases, hemicellulases and pectinases, wherein the host cell is a filamentous fungus and is capable of secretion of the at least four different enzymes. This host cell can suitably be used for the production of an enzyme composition that can be used in a process for the saccharification of cellulosic material.

主权项

1. A process for producing an enzyme composition comprising at least four different Talaromyces cellulases, hemicellulases and/or pectinases comprising:
(a) providing a transformed host cell comprising at least four different heterologous polynucleotides encoding at least four different Talaromyces enzymes selected from the group consisting of cellulases, hemicellulases and pectinases, wherein said transformed host cell is a filamentous fungus and is capable of secreting said at least four different Talaromyces enzymes, (b) allowing production and secretion of said at least four different Talaromyces cellulases, hemicellulases and/or pectinases by said host cell, and (c) optionally, recovering of said enzyme composition.
