| Subculture procedure | ① Prepare 1-2 plates as mentioned above; 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 two plates, each plate containing about 200 μ L, 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.
Growth conditions: 28°C, aerobic, integrated PDA, 5-7 days. Comprehensive PDA: Potato cooking liquid 1.0L, glucose 20.0g, KH2PO4 3.0g, MgSO4 7H2O 1.5g, trace amount of vitamin B1, agar 20.0g, pH 6.0±0.2. Sterilize at 121℃ for 15min. Potato cooking liquid: Weigh 200g of peeled potato pieces, boil in boiling water for 30min, collect the filtrate and dilute to 1.0L.
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
Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:

| Item | test results |
| viability | good viability,in 7 days plate colony is obvious |
| colony morphology: |
Small filamentous fungi, with obvious colonies on the integrated PDA medium, and the initial white of the plate layer hyphae, Spread growth, late production of green spores, yellow-green on the back of the medium |
| Conclusion: | good viability, no abnormal colony morphology, qualified |
