A process for efficient recycle fed-batch culture was carried out to increase cell mass and spore production by Lactic acid bacteria isolated from Kimchi. A large quantity of cell mass obtained by feeding concentration of sugar in recycle fed-batch culture. When the high density of salt was created that the cell mass was come-down. In this study, cultured in different feeding concentration of sugar conditions. Lactic acid bacteria by recycle fed-batch culture was investigated in 2L working volume of fermenter, obtained the maximum cell mass was 15.17g/L.
