Aspergillus micronesiensis

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 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, with obvious colonies on comprehensive PDA medium, white hyphae, dense and vigorous, and concentric circular tendrils towards the edge of the Agar plate
Sharing mode	Public welfare sharing

Talaromyces marneffei

No.: 146242

Storage conditions: 2~8 ℃

Product format: agar slant in 14mm test tube

Validity period: growing culture in 30days

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:25-28 ℃, aerobic, integrated PDA,5-7 days. Comprehensive PDA:20% potato juice 1L, glucose 20g ,KH₂PO₄ 3g, MgSO₄.7H₂O 1.5g, thiamine trace, agar 15g,pH 6.0±0.2.

Recovery steps:

(1)Prepare 1-2 pieces of PDA plates;

(2)Sterilize the surface of test tube for the agar slant, open it in the biosafety cabinet;

(3) Cut into the pieces with aseptic inoculation hoe and inoculation shovel (see attached page). the size of square pieces is 0.5 × 0.5cm2;

(4) Lay flat the small pieces to the center of the agar plate;

(5)Put the plates under the above 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 5-7 days plate colony is obvious
colony morphology:	small filamentous fungi have obvious colonies and white hyphae on integrated PDA culture medium, dense and exuberant, spreading to concentric circles on the edge of the plate, producing a small amount of yellow spores.
conclusion:	good viability, no abnormal colony morphology, qualified
