Potato boiling solution: 200g of potato, peeled, cut into pieces, put into distilled water and boil for 30min, take the filtrate to 1000mL for later use. 121 ℃,15min.

Recovery steps:

(1) Prepare 2 of above mentioned 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 5-7 days plate bacteria layer is obvious
colony morphology:	filamentous fungi, with obvious bacterial layer on comprehensive PDA medium, hyphae are brown, dense and low, hyphae are vigorously spreading and growing, producing brown spores.
Conclusion:	good viability, no abnormal colony morphology, qualified;
