    Abstract: The present invention relates to methods for producing a biological substance, comprising: (a) cultivating a fungal host cell in a medium conducive for the production of the biological substance, wherein the fungal host cell comprises a first nucleic acid sequence encoding the biological substance operably linked to a second nucleic acid sequence comprising a promoter variant selected from the group consisting of SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, and SEQ ID NO: 12; and a subsequence thereof; and hybrid and tandem promoters thereof; and (b) isolating the biological substance from the cultivation medium. The present invention also relates to the isolated promoter variants and to constructs, vectors, and fungal host cells comprising the promoter variants operably linked to nucleic acid sequences encoding biological substances.

    Abstract: The present invention relates to methods of producing a C4 dicarboxylic acid, comprising: (a) cultivating a filamentous fungal host cell comprising a polynucleotide selected from the group consisting of a heterologous first polynucleotide encoding a C4 dicarboxylic acid transporter, a heterologous second polynucleotide encoding a malate dehydrogenase, and a heterologous third polynucleotide encoding a pyruvate carboxylase; wherein the filamentous fungal host cell is capable of secreting increased levels of the C4 dicarboxylic acid compared to the filamentous fungal host cell without the heterologous polynucleotide when cultivated under the same conditions; and (b) recovering the C4 dicarboxylic acid. The present invention also relates to methods for increasing C4 dicarboxylic acid production, filamentous fungal host cells and malate dehydrogenase variants.

    Abstract: The present invention relates to mutants of a parent Trichoderma strain, comprising a polynucleotide encoding a polypeptide and one or more genes selected from the group consisting of a peptaibol synthetase gene, a paracelsin synthetase gene, a first terpene cyclase gene, a second terpene cyclase gene, and a third terpene cyclase gene, wherein one or more of the genes are modified rendering the mutant strain deficient in the production of one or more of the enzymes selected from the group consisting of a peptaibol synthetase, a paracelsin synthetase, a first terpene cyclase, a second terpene cyclase, and a third terpene cyclase compared to the parent Trichoderma strain 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.
