Aspergillus oryzae

Culture medium	Potato Glucose Agar (English Name: PDA): Potato Boiled Solution 1.0L, Glucose 20.0g, Agar 15.0g, Natural pH. Sterilization at 121 ℃ for 15min. Potato boiling liquid: weigh 200g of peeled potato pieces, boil in boiling water for 30min, and collect the filtrate to a constant volume of 1.0L.
Subculture procedure	(1) Prepare a test tube containing 5~10mL of liquid medium and 2 plates; (2) open it in the biosafety 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.
Growth conditions	28 ℃;5-7 days; Aerobic
Storage conditions	2-8 ℃
morphology	Small filamentous fungi, with obvious colonies on PDA medium, white hyphae, spreading and growing, dark yellow spores produced in the later stage, and the back of the medium was earthy yellow.
Sharing mode	Public welfare sharing

Aspergillus oryzae

No. 361469

Product format: agar slant in 14mm test tube

Validity period: growing culture, in 30 days

Biosafety level: 1, handle in ultra-clear 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 agar slant can be used directly. In principle, it can be used many times without contamination within the validity period, but viability will gradually decrease with time. 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, PDA,5-7 days. PDA: potato boiling solution 1.0L, glucose 20.0g, agar 15.0g (not included in liquid medium), natural pH. Sterilization at 121 ℃ for 15min. Potato boiling solution: weigh 200g of peeled potato pieces, boil in boiling water for 30min, and collect filtrate to a constant volume of 1.0L.

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

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