| 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 Transfer 0.5mL of liquid culture medium into a freeze-drying tube, dissolve it thoroughly, and then transfer it back into the liquid test tube, mixing 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. |

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 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 lose of viability.
Growth 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 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 hours.
Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:


| item | test result |
| viability | good viability, in 24h liquid medium become turbid, obvious strain layer occurs on the plate; colony is typical on marked plate |
| colony morphology: (above) |
size: 1-2mm shape: round edge: neat transparency: opaque Color: off-white uplift: middle raised surface: bright and smooth texture: moist and viscous |
| conclusion | good viability, no abnormal colony morphology, qualified |
