  • Patent number: 6143525
    Abstract: The invention provides a complex inducible promoter system from a phage of a lactic acid bacterium, especially one having the DNA sequence of SEQ. ID. No: 3 given in FIG. 2, or a DNA sequence essentially corresponding to those sequences, and a modification of (an essential part of) such promoter system in which the mitomycin C induction system is replaced by a good-grade system, e.g. a temperature-initiated induction system or a salt-initiated induction system. Also is provided a recombinant vector and a transformed lactic acid bacterium comprising (an essential part of) such promoter system. Further a process for producing a desired protein by such transformed bacterium is provided, comprising expressing a gene encoding said desired protein or a precursor thereof under control of such promoter system or an essential part thereof. Preferably, the transformed lactic acid bacterium is made food-grade due to using food-grade DNA sequences and/or removing non-food-grade DNA sequences.

  • Patent number: 5955258
    Abstract: The invention provides a process for the lysis of a culture of lactic acid bacteria, or a product containing such culture e.g. cheese, by means of a lysin through the in situ production of a homologous autolysin, or a heterologous autolysin obtainable from Gram-positive bacteria esp. from lactic acid bacteria. The gene encoding said autolysin is controlled by a promoter, preferably regulated by food-grade ingredients or parameters, to achieve an enhanced lysis after induction resulting in an enhanced production of total autolysin compared with the natural production lever of the homologous autolysin during fermentation or shortly thereafter. Other uses of the invention include preparing a mixture of peptides which are modified by peptidases freed after the lysis, using the autolysin as a bactericidal agent against spoiling bacteria or pathogenic bacteria for improving the shelf life of a product containing the lysed culture.
