| Subculture procedure | Prepare 1-2 fresh agar plates with typical bacterial colonies; ② Open the safety cabinet, burn the top with an alcohol lamp, quickly drip sterile water to break it, and then use tweezers to crush it; ③ Take 0.5mL of sterile water into the freeze-drying tube, dissolve it thoroughly, and mix well; ④ Transfer 0.2mL of bacterial suspension into a Agar plate, apply evenly, and repeat twice to obtain two plates; ⑤ Cultivate under the above conditions, and the strain can be used once it grows. |
