Abstract: A preparation method of a konjac granule includes the following steps: step 1: dissolving a konjac powder in hot water; step 2: subjecting a mixed solution obtained in step 1 to sterilization; step 3: conducting enzymatic hydrolysis at 50° C. to 70° C. for 2 h to 6 h; step 4: conducting enzymatic inactivation; step 5: conducting homogenization at 10 Mpa to 45 Mpa; step 6: adding a fully-dissolved sodium alginate solution and a flavor-modulating substance to a mixed solution obtained in step 5, and thoroughly mixing; and step 7: calcification and gelation: adding a calcium solution to a mixed solution obtained in step 6 for gelation to obtain the konjac granule. The preparation method improves the compactness of the konjac granule, increases a gel strength, and is conducive to extending a shelf life of a product.

Abstract: The present invention features methods and compositions relating to bacterial virulence polypeptides and nucleic acid sequences (e.g., DNA) encoding such polypeptides. Based on the present invention, a pathogenic infection may be treated, prevented, or reduced by administering to an infected mammal or plant a therapeutically effective amount of a composition that inhibits the expression or activity of a polypeptide encoded by the virulence factors. Also disclosed are methods for producing such polypeptides by recombinant techniques as well as methods for utilizing such polypeptides to screen for antibacterial or bacteriostatic compounds.
