Compositions and devices are described that provide controlled release of beneficial bacteria to the oral cavity. Such bacteria can subsequently colonize the oral cavity and displace or suppress the growth of pathogenic microorganisms. Described devices include a stabilized preparation of such beneficial bacteria and provide a consumable liquid, wet foam, or gel that includes such bacteria when used.

Aspects of the present invention relate inter alia to compositions which may have utility as anti-microbials. Such antimicrobial compositions may be for use in promoting wound healing and/or the treatment of microbial infections. In certain embodiments, the invention relates to an antimicrobial composition and/or combinations comprising copper gluconate and zinc gluconate which may be for use in treating and/or preventing infections and/or promoting wound healing. Certain aspects of the present invention further elate to an antimicrobial composition and/or device comprising copper gluconate, zinc gluconate and Lactobacillus plantarum for use in treating infections and/or promoting wound healing. Also encompassed by the present invention are methods of treating microbial and/or fungal infections in a subject, for example infections of the genital tract. Aspects of the present invention include a composition comprising a zinc salt and a copper salt, wherein the zinc salt is zinc gluconate and the copper salt is copper gluconate.

Provided are a method of manufacturing a functional polysaccharide, the method including: preparing a cell containing a polysaccharide; crushing the cell to extract polysaccharide to the outside of the cell to obtain an extract; and purifying the extract by removing at least one of crude protein, crude fat, and crude powder from the extract, and a cosmetic composition for skin moisturizing or skin elasticity improvement, the cosmetic composition including the functional polysaccharide as an active ingredient.
