Paecilomyces variotii Bainier

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.

Paecilomyces variotii Bainier

Storage conditions : 2~8 ℃

No. : 122244

Product format: freeze dried,200ul

Validity period: 24 months

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 ℃, aerobic, integrated PDA. Comprehensive PDA: potato boiling juice 1000mL, potassium dihydrogen phosphate 3.0g, magnesium sulfate heptahydrate 1.5g, glucose 20.0g, vitamin B1 10mg, agar 20g,pH natural. 121 ℃,15min. Potato boiling solution: 200g of potato, peeled, cut into pieces, boiled in distilled water for 30min, constant volume of filtrate to 1000mL for later use. 121 ℃,15min.

Recovery steps:

(1)Prepare 2 pieces of PDA plates or 2 agar slants;

(2)Open the ampoule 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 sterile water into the freeze dried ampoule, make it fully dissolved, and distribute the solution to the plates well in 200ul/plate;

(4)Place the plates uprightly and agar slant obliquely under the above culture conditions 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 days plate colony is obvious
colony morphology:	The morphology of the bacteria is obviously visible in the integrated PDA agar medium. The hyphae are white at the beginning and black spores are produced later. It is dry and vigorous. Spread to the surface of the culture medium.
Conclusion:	good viability, no abnormal colony morphology, completely consistent with the above figure, qualified
