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 48-72 hours.

Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:
