The present invention relates to a novel Bifidobacterium bifidum MG731 strain and a composition for preventing or treating cancers, comprising the same. Specifically, the Bifidobacterium bifidum MG731 strain of the present invention has effects of inhibiting the proliferation of cancer cells, decreasing the mobility of cancer cells, inhibiting the neoangiogenesis, and increasing the anticancer immune response as well as reducing the expression of inflammatory factors, thereby having effects of preventing or treating cancers or inflammatory diseases. In addition, when used in combination with an anticancer chemotherapeutic agent or an anticancer immunotherapeutic agent, the Bifidobacterium bifidum MG731 strain of the present invention exhibits a better anticancer effect. In addition, the present invention relates to a novel Lactococcus lactis GEN3033 strain and a composition for preventing or treating cancers, comprising the same. Specifically, the Lactococcus lactis GEN3033 strain of the present invention exhibits effects of directly inhibiting the proliferation of cancer cells and enhancing immunity, thereby having effects of preventing or treating cancers. In particular, the strain has an excellent anticancer effect by secreting metabolites having an anticancer effect while being established in the gut. In addition, when used in combination with an anticancer chemotherapeutic agent or an anticancer immunotherapeutic agent, the Lactococcus lactis GEN3033 strain of the present invention exhibits a better anticancer effect.

Provided is a tetanus toxin protein variant, the tetanus toxin protein variant comprising a C fragment of the tetanus toxin protein and a partial fragment of a translocation region of the tetanus toxin protein. Further provided is a proteoglycan conjugate, the proteoglycan conjugate comprising a polysaccharide from Streptococcus pneumoniae and a truncated tetanus toxin protein. Also provided is a method for improving immunogenicity, the method comprising the following steps: providing a proteoglycan conjugate comprising a polysaccharide from Streptococcus pneumoniae and a truncated tetanus toxin protein.

The present invention is directed to a novel isolated bacterial strain of the Streptococcus salivahus (S. salivahus) species. More in particular, a strain of the S. salivahus species deposited at BCCM under accession number LMG P-31813. Further, the present invention relates to a composition comprising an isolated bacterial strain of the S. salivahus species. In another aspect, the present invention further relates to the isolated bacterial strain according to the present invention or the composition according to the present invention for use in immunomodulation and/or in the treatment and/or prevention of infections of diseases.

The present invention provides for recombinant Endo-S mutants that exhibit reduced hydrolysis activity and increased transglycosylation activity for the synthesis of glycoproteins wherein a desired sialylated oxazoline or synthetic oligosaccharide oxazoline is added to a core fucosylated or nonfucosylated GlcNAc-protein acceptor. Such recombinant Endo-S mutants are useful for efficient glycosylation remodeling of IgG1-Fc domain to provide different antibody glycoforms carrying structurally well-defined Fc N-glycans.

The invention is directed to a lactose-positive, galactose-negative, Streptococcus thermophilus strain releasing glucose during milk fermentation. This Streptococcus thermophilus strain carries mutation in the glcK gene, in the ccpA gene, in the lacZ gene and/or in the ptsH gene, and optionally in one or more genes, in particular one gene, encoding a protein of the mannose-glucose-specific PTS. The invention also concerns a composition comprising at least one, lactose-positive, galactose-negative, Streptococcus thermophilus strain of the invention, and the use of this strain or composition to manufacture a fermented dairy product.

The present invention relates to the use of at least one lactic acid bacterium, or a composition comprising thereof or conditioned thereby, for increasing or maintaining a Faecalibacterium prausnitzii population.

The present invention relates to media and fermentation methods for producing polysaccharides in bacterial cell culture. In one aspect, the invention relates to a complex culture medium comprising a vegetable hydrolysate, a yeast extract, and a carbon source. In another aspect, the invention relates to a defined media having a total amino acid concentration greater than about 50 mM. A further aspect of the invention relates to the use of fed batch and perfusion fermentation methods for cultivating polysaccharide-producing bacteria.
