Subculture procedure	① Prepare 1-2 of the above 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 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.

Yarrowia lipolytica

Storage conditions : 2~8 ℃

No. : 186960

Product format: freeze dried,200ul

Validity period : freeze-dried tube 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 :28-30 ℃, aerobic, YM medium. YM medium: yeast extract, 3.0g malt extract, 3.0g glucose, 10.0g protein block, 5.0g agar, 20.0g distilled water 1000 ml ,pH 6.2 +/- 0.2,121 ℃,15min.

Recovery steps:

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

(2) Open it in biosafety cabinet, heat the tip of ampoule in a flame, quickly drop sterile water to creak it, then break it with forceps;

(3) Open the ampoule in the biosafety cabinet, heat the tip of ampoule in a flame, directly dispense 200ul of the liquid suspension into a YM agar plate evenly.

(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 40h YM plate colony obvious
colony morphology	Size: General color: milky white shape: round edge: neat edge dry and wet: semi-dry and smooth: slightly rough Transparency: opaque uplift: raised
Conclusion	good viability, and colony morphology is not abnormal, completely consistent with the above figure, qualified
