Patent ID: 11512281

Abstract:
Endophytic microbial strains as biocatalysts isolated from fresh plant samples, their compositions, and methods of use thereof to enhance the growth and/or yield of a plant in the presence of reduced (synthetic or otherwise) nitrogen and phosphorus fertilizers are provided. The selected endophytic microbial strains serve as biocatalysts to solubilize organic (proteinaceous) nitrogen otherwise unavailable to plants for their nutritional needs. In addition, selected endophytic microbial strains serve as biocatalysts to solubilize mineral-P and mineralize organic-P otherwise unavailable to plants for their nutritional phosphate needs. Thus defined, biocatalysts will serve to replace or reduce the requirement of (synthetic or otherwise) nitrogen and phosphorus fertilizers. Also provided are materials and methods for inoculating plants with these biocatalysts at carefully selected inoculum densities to reliably reduce the amount of nitrogen and phosphorus fertilizers by 30-50% thus accomplishing optimal yields in a cost-effective manner.
