Aspergillus niger
Culture medium CDA: 3g of sodium nitrate, 1g of dipotassium hydrogen phosphate, 0.5g of magnesium sulfate, 0.5g of potassium chloride, 0.01g of ferrous sulfate, 30g of sucrose, 15g of agar, 1.0L of distilled water and 6.2±0.2 of pH. 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 1-2 of above mentioned plates; 

(2)Open 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; 

(3) Draw 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; 

(4) Put the plates under the above culture conditions for cultivation for 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 5-7 days, plate colony is obvious
colony morphology:

Small filamentous fungi, with obvious colonies on comprehensive PDA medium, and yellow initial hyphae,

dense exuberant, post-producing black spores full of plates

Conclusion: good viability, no abnormal colony morphology, qualified
