The present invention provides a new fungal production system comprising a fungal host strain ofwherein the endogenous cellulase secretion is less than 20% of the endogenous cellulase secretion ofstrain UV 18-25. Preferably, also the secretion of endogenous protease, endogenous &#x3b2;-glucanase and endogenous cellobiohydrolase is less than 20% of the secretion ofstrain UV 18-25. Furthermore, fungal host strains are provided wherein several genes have been disrupted. According to another aspect of the invention a method for homologous and/or heterologous production of a pure protein with a purity of higher than 75%, comprising expressing a gene encoding said protein in the strains according to the invention have been described. Furthermore, a method for production of artificial protein mixes comprising expressing a gene encoding each of said proteins in a strain according to the invention have been disclosed. Finally a method for simplified screening of strains functionally expressing a desired enzyme by application of said strains have been provided.

Fungal production system

A novel transformation system in the field of filamentous fungal hosts for expressing and secreting heterologous proteins or polypeptides is described. The invention also covers a process for producing large amounts of polypeptide or protein in an economical manner. The system comprises a transformed or transfected fungal strain of the genus, more particularly ofand mutants or derivatives thereof. It also covers transformants containingcoding sequences, as well expression-regulating sequences ofgenes. Also provided are novel fungal enzymes and their encoding sequences and expression-regulating sequences.
