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 5-7 days.

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

item	test result
viability:	good viability, in 5-7 days plate colony is obvious
