| Abstract: | The culture condition of Bacillus JY-LZ, one strain of probiotics that can produce lactic acid, was studied in shake flask. The optimum culture conditions were found. When volume of inoculum was 5～10%, temperature was 30～40℃, volume of media in 100ml flask was 30mL(K_La=177.5h~(-1)),and pH(before sterilization) was 7～9 , the 48h cell density was over 10~(10)/mL, and the sporulation rate was over 50%. The results show that the optimum culture conditions can be applied in practical production. |
