| Growth conditions | 30 ℃, 48-72 hours, facultative anaerobic |
| Subculture procedure | ① Prepare 2 plates; 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 and pour it into the freeze-drying tube. After fully dissolving, transfer it back to the liquid test tube 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. |
