Culture medium MRS medium (MRS): peptone 10.0g, beef paste 10.0g, yeast powder 4.0g, glucose 20.0g, magnesium sulfate 0.2g, sodium acetate 5.0g, triammonium citrate 2.0g, dipotassium hydrogen phosphate 2.0g, manganese sulfate 0.04g, Tween 80 1.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L. pH 5.7±0.2. Sterilization at 121 ℃ for 15min.
Subculture procedure (1) Prepare a test tube containing 5~10mL of liquid medium and 2 plates; (2) Open it in the safety cabinet, heat the tip of ampoule in a flame, quickly drop sterile water to creak it, then break it with forceps; (3) draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; (4) inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; ⑤ Put all the liquid test tubes and plates under the above culture conditions for cultivation, and the strains can be used when they grow.

Recovery steps:

(1)Prepare a test tube containing 5-10mL of liquid culture medium and 2 plates; 

(2) Open the ampoule in the biosafety cabinet, heat the tip of ampoule in a flame, quickly drop sterile water to creak it, then break it with forceps; 

(3) Draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; 

(4) Inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; 

(5) Put all the liquid test tubes and plates under the above culture conditions for cultivation, and the strains can be used when they grow.

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

Item test results
viability good viability, in 24 hours liquid medium become turbid,  obvious strain layer occurs on the plate; colony is typical on marked plate
colony morphology:

Size: 1-2mm Shape: Round Edge: Neat Transparency: Opaque

color: milky white uplift: middle convex surface: bright and smooth texture: moist and easy to stir

Conclusion: good viability, no abnormal colony morphology, qualified
