It is characterized by breeding lactic acid bacteria by an independent culture method which cultures while giving various stresses so as to induce and express the excellent survival ability of lactic acid bacteria in nature to obtain an active bacterial cell And a fermented fermented lactic acid bacterium in which the inherent viability of the bacterium obtained by the culture is induced and expressed. A method for producing a solid fermented product of lactic acid bacteria,(1) a liquid culture step in which lactic acid bacteria are cultured using a liquid medium,(2) a solid culture step consisting of one step or a plurality of steps in which the lactic acid bacteria cultured in the step (1) is cultured in a solid medium which is a solid food mixture, wherein the solid medium contains at least carbonates and embryos and embryo koji and / Or a polyphenol-containing plant body, wherein the solid medium used in the final step of the solid culture includes a polyphenol-containing plant body, a solid culture step of growing lactic acid bacteria on the surface of the solid medium,Wherein the lactic acid bacterium solid fermented product is a lactic acid bacterium solid fermented product containing the lactic acid bacteria on the surface of the solid medium used in step (2).乳酸菌本来の優れた生残能を誘導発現させるべく、種々のストレスを賦与しながら培養する独自培養法により乳酸菌を育種し活性菌体とすることを特徴とし、そのような活性菌体を得ることができる培養法、及び培養により得られた菌本来の生残能を誘導発現させた乳酸菌固体発酵物の提供。 乳酸菌固体発酵物の製造方法であって、(1) 乳酸菌を、液体培地を用いて培養する液体培養工程、(2) 工程(1)で培養した乳酸菌を固形食材混合物である固体培地で培養する、1工程又は複数工程からなる固体培養工程であって、固体培地は少なくとも炭酸塩及び胚芽、並びに胚芽麹及び/又はポリフェノール含有植物体を含み、固体培養の最終工程で用いる固体培地はポリフェノール含有植物体を含む、乳酸菌を固体培地表面で増殖させる固体培養工程、を含み、乳酸菌固体発酵物が工程(2)で用いた固体培地表面に前記乳酸菌が含有されている乳酸菌固体発酵物である、製造方法。
