Penicillium sp.

Subculture procedure	① Prepare 1 test tube containing 5-10 mL of liquid culture medium and 2 plates; 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 Transfer 0.5mL of liquid culture medium into a freeze-drying tube, dissolve it thoroughly, and then transfer it back into the liquid test tube, mixing well; ④ Transfer 0.2mL of bacterial suspension into a Agar plate, apply evenly, and repeat twice to obtain two plates; ⑤ Place all liquid test tubes and plates under the above cultivation conditions, and the bacterial strains can be used once they grow.
Growth conditions	28 ℃; 3 days; aerobic;
Storage conditions	2-8 ℃
Safety level	1
morphology	Small filamentous fungi have obvious colonies on the comprehensive PDA medium, with white colonies at the beginning and green spores later produced. They grow all over the agar plate and the back of the medium is yellow
Sharing mode	Public welfare sharing

Penicillium sp.

Storage conditions : 2~8 ℃

No. : 353380

Product format: freeze dried, 200ul

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, integrated PDA agar, 3 days, integrated PDA agar: potato boil 1.0L, glucose 20.0g,KH2PO4 3.0g,MgSO4·7H2O 1.5g, vitamin B1 trace, agar 20.0g,pH 6.0±0.2. 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.

Recovery steps:
(1)Prepare 1-2 pieces of PDA 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 24-48 hours.

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

item	test results
viability	good viability, in 3 days strain layer is obvious
colony morphology: (above)	small filamentous fungi have obvious colonies on comprehensive PDA medium, white at the beginning of the colony, green spores at the end, covered with plates, and yellow on the back of the medium.
conclusion	good viability, no abnormal colony morphology, qualified
