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.
