    摘要: The present invention relates to a bacterial host cell in which a first chromosomal gene encoding a first alanine racemase and a second chromosomal gene encoding a second alanine racemase have been inactivated. Said bacterial host cell comprises – either on a plasmid comprising at least one autonomous replication sequence or present as multiple copies in the chromosome – a gene expression cassette comprising a polynucleotide encoding at least one polypeptide of interest, operably linked to a promoter, and a polynucleotide encoding a third alanine racemase, operably linked to a promoter. The present invention further relates to a method for producing at least one polypeptide of interest based on cultivating the bacterial host cell of the present invention.

    摘要: The present invention relates to a Bacillus host cell belonging to the species Bacillus lichemformis or Bacillus pumilus in which the chromosomal alr gene has been inactivated. Said bacterial host cell comprises a plasmid comprising at least one autonomous replication sequence, a first polynucleotide encoding at least one polypeptide of interest, wherein said first polynucleotide is operably linked to a promoter, and a second polynucleotide encoding an alanine racemase which is not native to the host cell, wherein said second polynucleotide is operably linked to a promoter. The present invention further relates to a method for producing at least one polypeptide of interest based on cultivating the bacterial host cell of the present invention.

    摘要: The present invention relates to a Bacillus licheniformis host cell for production of biological compounds with increased purity. Specifically, the invention relates to a Bacillus licheniformis host with one or more genetic modifications selected from a) a genetic modification causing compared to an unmodified control cell an increased expression of at least one of the genes selected from the group consisting of degQ, degll, degS, degR, and phrG, b) a genetic modification causing compared to an unmodified control cell an increased autophosphorylation activity of the DegS protein, and c) a genetic modification causing compared to an unmodified control cell a reduced phosphatase activity of the DegS protein. The present invention further relates to a method for production of at least one compound of interest with increased purity based on cultivating the bacterial host cell of the present invention.

    摘要: The present invention relates to a Bacillus host cell for increased production of biological compounds. Specifically, the invention relates to a Bacillus host with genetic modifications that lead to decreased production of components of biofilm and increased levels of phosphorylated De-gll. Said Bacillus host comprises at least one gene expression cassette with a polynucleotide encoding at least one polypeptide of interest, operably linked to a promoter for the production of compounds. The present invention further relates to a method for increased production of at least one polypeptide of interest based on cultivating the bacterial host cell of the present invention.
