Aspergillus luchuensis

Subculture procedure	① Prepare 1-2 plates as 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 ℃; 3-5 days; aerobic
Storage conditions	2-8 ℃
Safety level	1
morphology	Small filamentous fungi have obvious colonies on the comprehensive PDA medium, with white and dense hyphae that spread and grow towards the edge of the Agar plate. The back of the medium is yellow
Sharing mode	Public welfare sharing

Aspergillus luchuensis

Storage conditions: 2~8 ℃

No. 361062

Product format： freeze dried, 200ul

Validity period: 6 years

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 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 of 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 loss of viability.

Growth conditions: 28°C, aerobic, integrated PDA, 3-5 days. Comprehensive PDA: Potato cooking liquid 1.0L, glucose 20.0g, KH2PO4 3.0g, MgSO4 7H2O 1.5g, trace amount of vitamin B1, agar 20.0g, pH 6.0±0.2. Sterilize at 121℃ for 15min. Potato cooking liquid: Weigh 200g of peeled potato pieces, boil in boiling water for 30min, collect the filtrate and dilute to 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)The plate is cultured under the above-mentioned 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 results
viability	good viability,in 5 days plate colony is obvious
colony morphology:	Small filamentous fungi, with obvious colonies on the integrated PDA medium, and the plate layer hyphae are white and dense, sprawling and producing white spores, the back of the medium is yellow and wrinkled.
Conclusion:	good viability, no abnormal colony morphology, qualified
