    摘要: 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. When required, the desired protein can be secreted by the lactic acid bacterium if a DNA sequence fused to the gene encoding the desired protein is present which effects secretion of the desired protein or its precursor. The process can be used in a fermentation process, in which the desired protein causes lysis of the bacterial cells so that the contents of the cells can be released, or in which the desired protein is an enzyme involved in flavour formation, or in which the desired protein has a function in a cheese production process, such as chymosin or a precursor thereof, or an enzyme involved in flavour formation.

    摘要: 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.

    摘要: The present invention provides a method of preparing an edible product comprising non-viable bacteria providing a health benefit, the method comprising subjecting viable bacteria to at least two sub-lethal treatments to obtain the non-viable bacteria providing a health benefit, each sub-lethal treatment on its own not being sufficient to render the bacteria non-viable. The method porvides non-viable bacteria providing health benefits but which can conveniently be incorporated into a range of edible products.
