This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,970.

Background and Problem Solved

The original patent disclosed the use of Bacillus subtilis strain DSM 32685 for inhibiting bacterial colonization or infection in animals. However, there remains a need to improve the antimicrobial activity, optimize the gut microbiome, reduce antibiotic resistance, and enhance the growth-promoting effects of this strain. The present invention addresses these limitations by introducing synergistic combinations of antibiotics, probiotic blends, prebiotics, enzyme blends, bacteriocin-producing strains, and heat-treatment processes to create enhanced Bacillus subtilis strains.

Novelty and Inventive Step

The new invention provides a significant improvement over the original patent by introducing novel combinations and processes that enhance the antimicrobial activity, optimize the gut microbiome, reduce antibiotic resistance, and improve the growth-promoting effects of the Bacillus subtilis strain. The synergistic combinations, probiotic blends, prebiotics, enzyme blends, bacteriocin-producing strains, and heat-treatment processes are not obvious from the original patent and provide a non-obvious solution to the limitations of the original invention.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of different antibiotics, probiotic strains, prebiotics, enzyme blends, and bacteriocin-producing strains. Additionally, the invention could be implemented in different animal species, such as swine or cattle, or in different types of animal feed, such as aquaculture feed.

Potential Commercial Applications and Market

The present invention has significant commercial potential in the animal feed industry, particularly in the poultry and swine sectors. The invention could also be applied in the human probiotics market, where there is a growing demand for gut microbiome optimization and antibiotic resistance reduction. The market for animal feed additives is expected to grow significantly in the coming years, driven by the increasing demand for sustainable and efficient animal production.
