| Subculture procedure | ① Cultivate the bacteria into a bacterial suspension according to the cultivation conditions first; ② Measure the absorbance of bacterial suspension and calculate the initial concentration of bacterial suspension according to the standard formula; ③ The actual concentration after freeze-drying is obtained by multiplying the initial concentration by the survival rate; ④ Dilute the bacterial suspension according to the actual concentration after freeze-drying to obtain the target concentration, and then divide and freeze dry it; |
