    摘要: The present invention relates to a mutant of a parent filamentous fungal cell, comprising: a polynucleotide encoding a polypeptide of interest; a racA gene encoding a Rho-GTPase RacA protein, wherein the racA gene is modified rendering the mutant partially or completely deficient in the production of the Rho-GTPase RacA protein; and a ras2 gene encoding a GTPase Ras2 protein, wherein the GTPase Ras2 protein is modified to produce a GTPase Ras2 variant comprising a substitution at a position corresponding to position 16 of SEQ ID NO: 11, wherein the combination of the modified racA gene and the Ras2 variant synergistically increases the productivity of the mutant in the production of the polypeptide of interest. The present invention also relates to a method of producing a polypeptide of interest with such a mutant.

    摘要: The present invention relates to isolated polypeptides having beta-glucanase activity, catalytic domains, carbohydrate binding modules and polynucleotides encoding the polypeptides, catalytic domains or carbohydrate binding modules. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides, catalytic domains or carbohydrate binding modules. The present invention further relates to processes for producing fermentation products from starch-containing or cellulosic-containing material, as well as an enzyme blend or composition, or a recombinant host cell or fermenting organism suitable for use in processes of the invention.
