  • Polypeptides and Nucleic Acids Encoding Same
    Publication number: 20120295000
    Abstract: The present invention relates to isolated polypeptides and isolated nucleic acid sequences encoding the polypeptides, as well as methods for producing and using the polypeptides in animal feed. An example of a polypeptide of the invention is the so-called L12 protein from Bacillus licheniformis ATCC 14580 which improves the Feed Conversion Ratio (FCR) and/or acts as a gut microflora modulator. The invention furthermore relates to the probiotic use of strains of Bacillus which produce proteins related to L12.
    Type: Application

  • Methods for producing polypeptides in mutant cells
    Patent number: 7241614
    Abstract: The present invention relates to methods for producing a polypeptide of interest by (a) cultivating a mutant of a parent Aspergillus cell, wherein (i) the mutant 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 responsible for the biosynthesis or secretion of at least one toxin, and (ii) the mutant produces less of the toxin than the parent Aspergillus cell when cultured under the same conditions; and (b) isolating the polypeptide from the culture medium. Also, mutants of Aspergillus cells are provided, as well as methods for obtaining the mutant cells.
