    摘要: The present invention relates to methods for producing a recombinant polypeptide of interest, the method comprising the steps of: a) providing a polynucleotide library encoding one or more polypeptides of interest, wherein the library was prepared in an expression cloning vector comprising at least the following elements: i) a polynucleotide encoding a selectable marker; ii) a fungal replication initiation sequence, preferably an autonomously replicating sequence (ARS); and iii) a polynucleotide comprising in sequential order: a promoter derived from a fungal cell, a cloning-site into which the library is cloned, and a transcription terminator; b) transforming a mutant of a parent filamentous fungal host cell with the library, wherein the frequency of non-homologous recombination in the mutant has been decreased compared to the parent; c) culturing the transformed host cell obtained in (b) under conditions suitable for expression of the polynucleotide library; and d) selecting a transformed host cell which produces the polypeptide of interest.

    摘要: Cellulose-containing fabric is desized by treating with an enzyme hybrid having a catalytically active amino acid sequence of an enzyme such as a lipase or an amylase linked to an amino acid sequence containing a cellulose-binding domain. The enzyme amino acid sequence may be of an .alpha.-amylase obtainable from a species of Bacillus such as Bacillus licheniformis, or of a lipase obtainable from a species of Humicola, Candida, Pseudomonas or Bacillus. The cellulose-binding domain may be from a cellulase, a xylanase, a mannanase, an arabinofuranosidase, an acetylesterase or a chitinase. The enzyme hybrid is obtained from a transformed host cell containing an expression cassette having a DNA sequence encoding the enzyme hybrid. A desizing composition is formed containing the enzyme hybrid and a wetting agent.
