Multi-bacteria fermentation technology first implants beneficial bacteria that can strongly decompose miscellaneous bacteria, then injects a precise proportion of nitrogen and oxygen, and implants bacteria with different properties in stages. The beneficial bacteria make aerobic bacteria and anaerobic bacteria at different stages of fermentation form different dominant bacteria. Through the first generation of multiple dominant bacteria, the highest enzyme activity in biological history can be achieved. This technology is the SMAP innovative fermentation system that was awarded an international patent after 6 years of research by the ESMAY R&D team and the University of Pennsylvania.
