  • strains useful for inhibition of
    Patent number: 11453856
    Abstract: The Lactobacillus curvatus strain deposited as DSM18775 is used as a biopreservative culture in a wide range of meat products due to its production of bacteriocin. The present invention relates to Lactobacillus curvatus strains having an extended lag phase of at least 24 hours at 30° C. relative to DSM18775. In a presently preferred embodiment, the strains are mutants of DSM18775, such as the Lactobacillus curvatus strain deposited as DSM32590 and the Lactobacillus curvatus strain deposited as DSM 32591. Further, the invention relates to a method for inhibiting Listeria in a food product comprising adding bacteria of a Lactobacillus curvatus strain according to the invention to a food product in a concentration of at least 105 CFU/g.

  • Antibiotic-sensitive lactic acid bacteria strains
    Patent number: 8440450
    Abstract: Many probiotic Bifidobacteriaceacontains an active tetW that renders the cells resistant to tetracycline. This may present a risk of a horizontal transfer of functional antibiotic genes. The present invention relates to a method of obtaining novel tetracycline-sensitive strains of the genus of Bifidobacteriacea (Bifidobacterium sp.). In particular, the present invention relates to novel antibiotic-sensitive strains obtained from antibiotic-resistant probiotic strains and the use of such novel strains for the preparation of a food or feed product or a dosage form comprising viable organisms.

  • Tetracycline-sensitive bifidobacteria strains
    Patent number: 8226936
    Abstract: Many probiotic Bifidobacteriacea contains an active tetW that renders the cells resistant to tetracycline. This presents a theoretical risk of a horizontal transfer of functional antibiotic genes. The present invention relates to novel tetracycline-sensitive strains of the well-known probiotic Bifidobacterium animalis subsp. lactis strain BB-12® and the use of such novel strains for the preparation of a food or feed product or a dosage form comprising viable organisms.
