The present invention concerns an E. coli strains expressing high level of α-Gal, in particular selected in the group consisting of E. coli Nissle 1917 strain, E. coli O111 strain, E. coli O86:B7 strain, and mixture thereof, as a probiotic and/or feed additive and/or oral vaccine in a non-human animal, in particular fish and poultry, to prevent and/or reduce an infectious disease caused by a pathogen expressing α-Gal on its surface.

A method is provided for improving the technological and nutritional properties of gluten-free food matrices based on a fermentation protocol using selected lactic bacteria as starters. The bacteria used are Lactobacillus plantarum strain DSM 33412 and Lactobacillus brevis strain DSM 33413. The method is useful in the processing of gluten-free flowing food material.

A method useful for providing a phytonutrient to a subject via mediation of the subject’s microbiome is disclosed. The method includes administering a phytofunctional composition to a subject change the phytonutrient producer status of the subject. The method may also include identifying a phytonutrient producer status of the subject by assessing a level of at least one of a preselected phytonutrient and a preselected phytonutrient precursor compound within the subject. A phytofunctional composition useful in the method is also disclosed, and comprises a phytonutrient precursor compound and an active agent. The active agent comprises a probiotic and/or a prebiotic, and is adapted to mediate production of the preselected phytonutrient in the gastrointestinal tract of the subject, thereby changing the phytonutrient producer status of the subject.

A synthetic mixture of human milk oligosaccharides (HMOs) consisting essentially of lacto -N-neotetraose (LNnT), lacto-N-tetraose (LNT), 2′-fucosyllactose (2′FL), 3′-O-sialyllactose (3′-SL), 6′-O-sialyllactose (6′-SL) either difucosyllactose (DFL) or 3-fucosyllactose (3-FL), preferably DFL, and optionally lactose. Said synthetic composition is useful for: treating or pre-venting viral and/or bacterial infection in a non-infant human; modulating the microbiota of a non-infant human; and/or improving the cognitive function of a non-infant human and as a pharmaceutical or nutritional composition.

Aquafeed, animal feed, and other food products, as well as nutritional and pharmaceutical compounds, chemicals and biomaterials are important commodities that can be produced at commercial scale by fermentation of microorganisms. The present invention provides a method for producing these valuable multi-carbon compounds from simple gas feedstocks, such as carbon dioxide, hydrogen and oxygen, by cultivating a consortium of microbial cells specially selected for this purpose in an aqueous culture medium. In addition to exploiting inexpensive feedstocks, such as waste industrial gas for this cultivation, the platform described herein also provides the advantage of removing carbon dioxide and other waste gases from industrial emissions, which would otherwise contribute to global climate change. Furthermore, the cultivation of a microbial consortium can provide highly nutritious components to a feed blend that might not be available from a monoculture.

The present invention provides high-complexity defined gut microbial communities capable of achieving substantial engraftment and having stability following human fecal community microbial challenge and methods of producing the same. Also provided are methods of using high-complexity defined gut microbial communities for the treatment of dysbiosis or a pathological condition in an animal.

The invention is directed to novel probiotic bacterial strains that colonize animal tissues, and in particular the gastrointestinal (GI) tract of aquatic animals grown in aquaculture environments and may further be engineered to express and deliver interfering RNA molecules configured to downregulate expression of one or more pathogen, or endogenous host genes.
