Aspergillus nidulans (Eidam) Winter

Subculture procedure	① Prepare 1-2 tablets mentioned above; ② Open the safety cabinet, burn the top with an alcohol lamp, quickly drip sterile water to break it, and then use tweezers to crush it; ③ Take 0.5mL of sterile water and transfer it into a freeze-drying tube. After fully dissolving the bacterial powder, transfer it into two plates, each Agar plate containing about 200 μ L, and apply evenly; ④ Place the petri dish under the above cultivation conditions for cultivation, and once the bacterial strain grows, it can be used.
Growth conditions	28 ℃; 5-7 days; aerobic;
Storage conditions	2-8 ℃
Safety level	1
morphology	Filamentous, spreading growth, initially white mycelium, later producing yellow spores

Validity period: 6 years

Biosafety level: 1 , handle in ultra-clean table or safety cabinet

Receiving notice: if any abnormality is found on the day of receipt, please contact the customer service within 24 hours. If it is overdue, it is deemed that the bacteria are well. The freeze dried culture shall be used up once and shall not be retained. The bacterial viability will resume after 1-2 generation of recovery and can be used normally. Handling instructions agar slant and suspension liquid is enclosed. Please operate in strict accordance with this instruction, otherwise the replacement of bacteria are not be available in case of aberrant growth and lose of viability.

Growth conditions:28 ℃, aerobic, chashel agar, 5-7 days, chashel agar: 3g sodium nitrate, 1g dipotassium hydrogen phosphate, 0.5g magnesium sulfate, 0.5g potassium chloride, 0.01g ferrous sulfate, 30g sucrose, 15g agar, 1.0L distilled water, pH 6.2±0.2. Sterilization at 121 ℃ for 15min.

Recovery steps:
(1)Prepare 1-2 of above mentioned plates;
(2)Open 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 5-7 days

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

item	test result
viability	good viability, in 5-7 days strain layer is obvious
colony morphology: (above)	Small filamentous fungi have obvious colonies on Cha's agar medium, with fluffy colonies, yellowish brown, dense and vigorous, and brown spores later.
conclusion	good viability, no abnormal colony morphology, qualified
