Provided are: a culture method with which it is possible to obtain active cells, the culture method being characterized in that lactic acid bacteria are bred by a proprietary culture method for culturing while imparting various stresses to induce and express exceptional inherent survivability in the lactic acid bacteria, and active cells are produced and a lactic acid bacteria solid fermentation product in which the inherent bacterial survivability resulting from the culturing is induced and expressed. A method for producing a lactic acid bacteria solid fermentation product, wherein: the production method includes (1) a liquid culture step for culturing lactic acid bacteria using a liquid medium, and (2) a solid culture step that comprises one or multiple steps for culturing the lactic acid bacteria cultured in step (1) on a solid medium that is a solid food mixture, the solid medium including at least a carbonate and germ as well as germ koji and/or a polyphenol-containing plant, the solid medium used in the final step of solid culture including a polyphenol-containing plant, and the solid culture step involving causing lactic acid bacteria to grow on the solid medium surface and the lactic acid bacteria solid fermentation product contains the lactic acid bacteria on the solid medium surface used in step (2).La présente invention concerne : un procédé de culture permettant dobtenir des cellules actives, ledit procédé de culture étant caractérisé en ce que des bactéries lactiques sont cultivées par un procédé de culture déposé pour la culture tout en les mettant dans diverses conditions de stress pour induire et exprimer une exceptionnelle capacité de survie inhérente chez les bactéries lactiques, et les cellules actives sont produites et un produit de fermentation solide de bactéries lactiques dans lequel est induite et exprimée la capacité de survie inhérente des bactéries résultant de la culture. Linvention concerne également un procédé de production dun produit
