FUNGAL CELLS AND FERMENTATION PROCESSES

摘要

The present invention provides an isolated fungal cell that is capable of producing one or more biomass-degrading enzymes and that exhibits increased or decreased expression or copy number of a polynucleotide encoding a PtaB-like protein. Also provided is a fermentation processes for producing one or more biomass-degrading enzymes comprising a fungal cells exhibiting increased or decreased expression or copy number of a polynucleotide encoding a PtaB-like protein. The biomass-degrading enzymes produced by the isolate fungal cell and fermentation processes of the present invention may be used in a process to produce soluble sugars from biomass.

主权项

1. An isolated fungal cell capable of producing one or more biomass-degrading enzyme, the fungal cell exhibiting an increase in copy number or expression, relative to a parental fungal cell from which the isolated fungal cell is derived, of a polynucleotide that encodes a polypeptide exhibiting from about 40% to 100% identity to SEQ ID NO: 1 or from about 50% to about 100% identity to the amino acid sequence of SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 7, SEQ ID NO: 9, SEQ ID NO: 11, or SEQ ID NO: 16.
