Recovery steps:

(1)Prepare 1-2 pieces of PDA plates;

(2)Sterilize the surface of test tube for the agar slant, open it in the biosafety cabinet;

(3) Cut into the pieces with aseptic inoculation hoe and inoculation shovel (see attached page). the size of square pieces is 0.5 × 0.5cm2;

(4) Lay flat the small pieces to the center of the agar plate;

(5) Put the plates under the above culture conditions, 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 result
viability:	good viability, in 4 days plate colony is obvious
colony morphology:	small filamentous fungi, colonies are obviously visible on comprehensive PDA medium, with white colonies, fluffy hyphae and exuberant.
conclusion:	good viability, no abnormal colony morphology, completely consistent with the above figure, qualified
