    摘要: The present invention relates to methods of producing a polypeptide, comprising: (a) cultivating a mutant of a parent Fusarium venenatum strain in a medium for the production of the polypeptide, wherein the mutant strain comprises a polynucleotide encoding the polypeptide and one or more (several) genes selected from the group consisting of pyrG, amyA, and alpA, wherein the one or more (several) genes are modified rendering the mutant strain deficient in the production of one or more (several) enzymes selected from the group consisting of orotidine-5′-monophosphate decarboxylase, alpha-amylase, and alkaline protease, respectively, compared to the parent Fusarium venenatum strain when cultivated under identical conditions; and (b) recovering the polypeptide from the cultivation medium. The present invention also relates to enzyme-deficient mutants of Fusarium venenatum strains and methods for producing such mutants.

    摘要: The present invention relates to methods for producing a polypeptide, comprising: (a) cultivating a mutant of a parent filamentous fungal cell under conditions conducive for the production of the polypeptide, wherein (i) the mutant cell comprises a first nucleic acid sequence encoding the polypeptide and a second nucleic acid sequence comprising a modification of at least one of the genes involved in the production of a trichothecene and (ii) the mutant produces less of the trichothecene than the parent filamentous fungal cell when cultured under the same conditions; and (b) isolating the polypeptide from the cultivation medium. The present invention also relates to mutants of filamentous fungal cells and methods for obtaining the mutant cells. The present invention also relates to isolated trichodiene synthases and isolated nucleic acid sequences encoding the trichodiene synthases. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid sequences as well as methods for producing the trichodiene synthases. The present invention further relates to mutants cells comprising a marker-free modification of a gene, and methods for obtaining and using such mutant cells.
