| Subculture procedure | ① Prepare 1-2 of the above plates; ② After disinfecting the surface of the ampoule tube, open it in a 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 slant and suspension liquid 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.
Gorwth conditions: 37 ℃,5% CO2, Columbia blood plate (ready-to-use type),24-48h.
Recovery steps:
(1) Prepare 1-2 of above mentioned plates;
(2) Open it in the biosafety cabinet, sterilize of the ampoule, heat the tip in a flame, quickly drop sterile water to creak it, then break it with forceps;
(3) draw 0.5ml of sterile water into the freeze dried ampoule, make it fully dissolved, and distribute the solution to the plates well in 200ul/plate;
(4) Put the plates under the above culture conditions for cultivation for 24-48 days.
Recovery record: According to the recovery instructions, the results of the cell recovery are reported as follows:

| Item | test results |
| viability: | good viability, in 24-48 hours strain layer become obvious;colony is typical on the streaked plate |
| colony morphology: (above) |
Size: 1-2mm Shape: Round Edge: Neat Transparency: Opaque Color: off-white uplift: middle convex surface: bright and smooth texture: moist and easy to stir |
| Conclusion: | good viability, no abnormal colony morphology, qualified |
