Abstract: The invention relates to a novel strain of lactic bacteria comprising at least one sequence selected from a group consisting of nucleotide sequences SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 3, SEQ ID No. 4, SEQ ID No. 5, SEQ ID No. 6, SEQ ID No. 7, SEQ ID No. 8 and to a method for the production of said strains. The invention also relates to the sequences SEQ ID Nos. 1-8 and to a nucleic acid, vectors and plasmids comprising said sequences. The invention further relates to food products, especially milk products containing said strains.

Abstract: The present invention provides methods for tagging and/or identifying microorganisms. In some preferred embodiments, the microorganisms are bacteria. In some particularly preferred embodiments, the bacteria are members of the genus Streptococcus, while in other embodiments, the bacteria are members of other genera. The present invention also provides microorganisms tagged using the methods set forth herein. In some preferred embodiments, the tagged microorganisms are bacteria. In some particularly preferred embodiments, the tagged bacteria are members of the genus Streptococcus, while in other embodiments, the tagged bacteria are members of other genera.

Abstract: The invention concerns lactic acid bacteria overproducing exopolysaccharides following mutation in the gene coding for ?-phosphoglucomutase. Said mutants are useful, in particular for preparing fermented products or for producing exopolysaccharides.

Abstract: The invention concerns an isolated polypeptide which is a bacteriocin called Sakacin G derived from Lactobacillus sakei 2512. The invention also concerns a nucleic acid molecule encoding for said bacteriocin and the use of said polypeptide as an active agent against pathogenic and undesirable flora in the preparation of food products.

Abstract: The invention concerns an isolated polypeptide which is a bacteriocin called Sakacine G derived from Lactobacillus sakei 2512. The invention also concerns a nucleic acid coding for said bacteriocin and the use of said polypeptide as active agent against pathogenic and undesirable flora in the preparation of food products.

Abstract: The invention concerns a plasmid having a replication mode which is not of the RCR type, and capable of being transferred in stable form into host lactic acid bacteria belonging at least to three different kinds.
