Subculture procedure	① Prepare 1 tube containing 5–10 mL liquid medium and 2 plates; ② Open in a safety cabinet, cauterize the top with an alcohol lamp, then quickly add sterile water to break it; subsequently crush it with forceps; ③ Pipette 0.5 mL liquid medium into the freeze-dried vial, dissolve thoroughly, then return to the liquid tube and mix well; ④ Pipette 0.2mL of the bacterial suspension onto a Agar plate and spread evenly. Repeat twice to obtain two plates; ⑤ Incubate all liquid tubes and plates under the specified conditions. The culture is ready for use once the bacterial strain grows.
