| Subculture procedure | ① Prepare one test tube containing 5-10 mL of liquid medium and two agar plates.② Within a biological safety cabinet, surface-sterilize and open the glass ampoule. Briefly flame the neck, then immediately apply a drop of sterile water to induce thermal cracking. Carefully open it using sterile forceps.③ Aspirate 0.5 mL of the liquid medium and inject it into the freeze-dried vial. Mix thoroughly to achieve complete resuspension. Transfer the entire suspension back into the original liquid medium test tube and mix well.④ Inoculate 0.2 mL of the resulting bacterial suspension onto each agar plate and spread evenly. Repeat this step to prepare a duplicate Agar plate.⑤ Incubate both the liquid culture tube and all agar plates under the aforementioned culture conditions. The culture is ready for use once visible growth is observed. |
