Subculture procedure	① Prepare 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 2 plates at a rate of 200 μ L per Agar plate 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 receiving goods, please contact customer service within 24 hours. if it is overdue, it will be regarded as good receiving goods. Dry powder shall not be retained after one use, and can be used after 1~2 generations of activation. please refer to the attached page for details of inclined plane and bacterial solution. Please activate in strict accordance with this instruction, otherwise the replacement service will not be provided if the strain is abnormal and inactivated.

Growth conditions:30°C, 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. 121 ℃,15min.

Recovery steps:

①Prepare 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;

③Suck 0.5mL of liquid culture medium into lyophilized tube, fully dissolve and return to liquid test tube again, and mix well;

④Absorb 0.2mL of bacterial suspension into the plate, coat evenly, repeat twice to obtain two plates;

⑤Place 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 result
viability	good viability,in 20h 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: yellow uplift: middle raised surface: smooth and bright texture: wet and easy to stir
conclusion:	good viability, no abnormal colony morphology, qualified
