    Abstract: 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.

    Abstract: The present invention relates to a novel Sphingomonas paucimobilis strain. In addition, it relates to a use of Sphingomonas paucimobilis strain. Specifically, it relates to a method or composition for preventing or improving skin wrinkles, enhancing skin elasticity, reinforcing a skin barrier, or moisturizing the skin using the strain. The novel Sphingomonas paucimobilis strain according to the present invention can inhibit the expression of a collagen-degrading enzyme MMP-1, and promote the expression of collagen, filaggrin and claudin-1 that exhibit effects to improve skin wrinkles, enhance skin elasticity, strengthen skin barrier, and moisturize the skin. Therefore, the strain can be usefully used to prevent or improve skin wrinkles, enhance skin elasticity, strengthen the skin barrier, and/or moisturize the skin.
