Subculture procedure	①Prepare 1-2 of the above plates (placed in an anaerobic environment for 24 hours of deoxygenation in advance) with typical bacterial colonies; ② Open the safety cabinet, burn the top with an alcohol lamp, and quickly drip sterile water (place it in an anaerobic environment for 24 hours to remove oxygen and break it, then use tweezers to crush it); ③ Take 0.5mL of sterile water (placed in an anaerobic environment for 24 hours of deoxygenation in advance) and transfer it into a freeze-drying tube. After fully dissolving the bacterial powder, transfer it into a Agar plate at a rate of 200 μ L per Agar plate and apply evenly; ④ Place the petri dish under the above cultivation conditions for cultivation, and once the bacterial strain grows, it can be used.
