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.
An isolated mutant Lactobacillus curvatus strain which is a mutant of the Lactobacillus curvatus strain deposited at the Deutsche Sammlung von Mikroorganismen and Zellkulturenwherein (DSMZ) under accession number DSM 18775, wherein the strain has an extended lag phase of at least 24 hours at 30° C. on MRS agar plates relative to strain DSM 18775 when assessed under identical conditions.
