Pseudomonas peli

Subculture procedure	① Prepare one test tube containing 5-10 mL of liquid culture medium and two 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.

Pseudomonas peli

Storage conditions: 2~8 ℃

No.: 139697

Product format: freeze dried,200ul

Validity period: Freeze-dried tube for 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. 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.

Recovery/subculture:28 ℃, aerobic, nutritious gravy medium. Nutritional agar medium: beef paste 3.0g, peptone 10.0g,NaCl 5.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L,pH7.0. 121 ℃,15min.

Recovery steps:

(1) Prepare 1 bottle of liquid medium or 2 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)Draw 0.5mL of liquid medium into the freeze dried ampoule,make the strain pellet fully dissolved. transfer the liquid suspension to the liquid media, and culture in plate shaker at 28℃ for 18-24 hours (140r/min); or directly dispense 200ul of the liquid suspension into a agar plate evenly, then put the plates in incubator at 28℃ for 24-48 hours.

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

item	test result
viability	good viability, in 20h liquid medium become turbid, bacterial liquid marking plate colonies are obviously typical
colony morphology	size: general color: light yellow shape: round edge: neat dry and wet: wet and smooth: smooth transparency: opaque uplift: uplift
Conclusion	good viability, and colony morphology is not abnormal, completely consistent with the above figure, qualified
