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

item	test result
viability	good viability, in 5 days strain layer is obvious
colony morphology	small filamentous fungi have obvious colonies on the integrated PDA medium, white and sparse at the initial stage, producing yellow-green spores, spreading and growing to the edge of the plate. after 5 days, the spores will fill the plate
conclusion	good viability, no abnormal colony morphology, qualified
