Abstract: The present invention relates to a pharmaceutical composition for preventing or treating inflammatory disease, which contains, as an active ingredient, a Bacillus amyloliquefaciens GF423 strain, a superoxide dismutase high-producing Bacillus amyloliquefaciens GF424 mutant strain, a superoxide dismutase (SOD) derived from one of these strains, or both the strain and the SOD. The superoxide dismutase derived from the Bacillus amyloliquefaciens GF423 strain (KCTC 13222BP), which is the active ingredient of the present invention, effectively suppresses or degrades reactive oxygen species, and thus has the effect of fundamentally preventing the causes of inflammatory bowel disease caused by reactive oxygen species. Therefore, the composition of the present invention may be developed into various products, including excellent drugs and health functional foods for preventing or treating inflammatory bowel disease.

Abstract: The present invention relates to a method for expressing a target protein on an exosporium forming the outermost surface of bacterial spores. More particularly, the present invention relates to a method for expressing a target protein on the surface of cells and spores using an exosporium as a matrix for surface expression, and methods for the production of a protein array, the production of antibodies, the separation of a certain substance from a mixture, bioconversion, and the improvement of a target protein, which are characterized by using the cells or spores having the target protein that was expressed on the surface by the above expression method.
