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.
