Abstract: The present invention relates to methods for constructing a recombinant fungal host cell comprising one or more copies of a polynucleotide construct integrated in its genome, said method comprising transforming a fungal host cell with an integrative polynucleotide construct comprising a first polynucleotide encoding a selectable marker, wherein the first polynucleotide, a 5? untranslated region thereof and/or a riboswitch operably linked therewith comprises a spliceosomal intron which has 5 nucleotides or less between its branch site and its acceptor site; and a second polynucleotide encoding a polypeptide of interest; as well as suitable polynucleotide constructs, resulting fungal host cells and methods of manufacture.

Abstract: The present invention relates to animal feed additives, which additives comprise a monocomponent xylanase derived from a strain of Byssochlamus, Chaetomium, Humicola, Malbranchea, Mucor, Myceliophthora, Paecilomyces, Talaromyces, Thermoascus, or Thielavia. In other aspects, the invention relates to monocomponent xylanase preparations, DNA constructs, recombinant expression vectors, host cells, and methods of producing monocomponent xylanase preparations.

Abstract: The invention relates to a genetically engineered variant of a parent starch debranching enzyme, i.e. a pullulanase or an isamylase, the enzyme variant having an improved thermostability at a pH in the range of 4-6 compared to the parent enzyme and/or an increased activity towards amylopectin and/or glycogen compared to the parent enzyme, to methods for producing such starch debranching enzyme variants with improved thermostability and/or altered substrate specificity, and to a method for converting starch to one or more sugars using at least one such enzyme variant.
