Abstract
The present invention relates to mutants of a parentstrain, comprising a polynucleotide encoding a polypeptide and one or more (several) genes selected from the group consisting of a first subtilisin-like serine protease gene, a first aspartic protease gene, a trypsin-like serine protease gene, a second subtilisin-like serine protease gene, and a second aspartic protease gene, 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 a first subtilisin-like serine protease, a first aspartic protease, a trypsin-like serine protease, a second subtilisin-like serine protease, and a second aspartic protease, respectively, compared to the parentstrain when cultivated under identical conditions. The present invention also relates to methods of producing a polypeptide in such mutants and methods for producing such mutants.
