However, to our knowledge,
the whole soybean fermented by LAB mixed with B. subtilis natto as
probiotics carrier food was not investigated. Besides, the solid-state
fermentation possesses several biotechnological advantages, such
as higher fermentation productivity, higher end-concentration of
products, higher product stability, lower catabolic repression,
cultivation of microorganisms specialized for water-insoluble
substrates and lower demand on sterility
