  The present invention is intended to provide an adjuvant having high safety to living bodies and an action to sufficiently reinforce immune function, and a vaccine comprising the adjuvant. Specifically, the present invention relates to 34 novel adjuvant candidate compounds, which have been identified by screening 145 food additives and 51 injection additives, using, as indicators, an increase in the antibody titer against influenza virus and a protective effect against infection with influenza virus, and then selecting those having the function of increasing the antiviral antibody titer in blood and the protective effect against viral infection. In addition, the present invention also relates to a vaccine comprising these adjuvant candidate compounds.

  Fusion proteins containing a targeting sequence, exosporium protein, or exosporium protein fragment that targets the fusion protein to the exosporium of a recombinant Bacillus cereus family member are provided. The fusion proteins further comprise an enzyme having ACC deaminase activity, a phospholipase, a lipase, a xylanase, a xylosidase, a lactonase, a chitosanase, a protease, a glucanase, a phytase, an acid phosphatase, a pectinase, a mannanase, and/or an expansin protein. Also provided are recombinant Bacillus cereus family members that express the fusion proteins, exosporium fragments derived from the recombinant Bacillus cereus family members, and formulations containing the recombinant Bacillus cereus family members or exosporium fragments. Plant seeds treated with the recombinant Bacillus cereus family members, exosporium fragments, or formulations are also provided. The invention further relates to methods for stimulating plant growth and/or promoting plant health using the recombinant Bacillus cereus family members, exosporium fragments, or formulations.
