| Subculture procedure | ① Prepare 1-2 of the above 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 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 piece 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. |

Receiving notice: if any abnormality is found on the day of receipt, please contact the customer service within 24 hours. If it is overdue, it is deemed that the bacteria are well. The freeze dried culture shall be used up once and shall not be retained. The bacterial viability will resume after 1-2 generation of recovery and can be used normally. Handling instructions of agar plate is enclosed. Please operate in strict accordance with this instruction, otherwise the replacement of bacteria are not be available in case of aberrant growth and loss of viability.
Growth conditions: 37 ℃, aerobic, nutrient agar medium, 18-24h. Nutritional agar medium: beef paste 3.0g, peptone 10.0g,NaCl 5.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L,pH7.0. Sterilization at 121 ℃ for 15min.
Recovery steps:
① Prepare a test tube containing 5~10mL of liquid culture medium and 2 plates;
②Open it in the safety cabinet, burn the top with an alcohol lamp, quickly drop sterile water to break it, and then break it with tweezers;
③ suck 0.5mL of liquid culture medium into freeze-dried tube, fully dissolve and return to liquid test tube again, and mix well;
④ Absorb 0.2mL of bacterial suspension into the plate, coat evenly, and repeat twice to obtain two plates;
⑤ Place all the liquid test tubes and plates under the above culture conditions, and the strains can be used when they grow out.

Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:
| Item | test results |
| viability: | good viability, in 18-24hours liquid medium become turbid,strain layer is obvious;colony is typical on the streaked plate |
| colony morphology: (above) |
Size: 2-4mm Shape: Round Edge: Untidy Transparency: Opaque Color: Off-white Bulge: Flat Surface: Bright and smooth Texture: Moist and sticky |
| Conclusion: |
good viability, no abnormal colony morphology, qualified |
