Please operate in strict accordance with this instruction, otherwise the replacement of bacteria are not be available in case of aberrant growth and loss of viability.

Growth conditions:28℃, aerobic, Czapek's agar, 5-7 days, Czapek's agar: sucrose 30.0 g, NaNO3 3.0 g, MgSO4 7H2O 0.5 g, KCl 0.5 g, FeSO4 4H2O 0.01 g, K2HPO4 1.0 g, agar 15.0 g, distilled water 1.0 L, pH 6.0-6.5, 121℃, 15min. 121℃, 15min.

Recovery steps:

①Prepare 1-2 of above mentioned plates;

②Open 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;

③Draw 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;

④Put the plates under the above culture conditions for cultivation 5-7days.

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

Item	test results
viability	good viability, in 6days strain layer become obvious
colony morphology: (above)	small filamentous fungus, in Czapek ' The colony on sagar medium is obvious, the initial hyphae are white, dense and vigorous, and the later black spores are covered with plates
Conclusion:	good viability, no abnormal colony morphology, qualified
