Streptomyces mobaraensis

Subculture procedure	① Prepare 2 of the above plates; ② After disinfecting the surface of the ampoule tube, open it in a 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 2 plates at a rate of 200 μ L per Agar plate 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.

Streptomyces mobaraensis

Storage conditions: 2~8 ℃

No. 186555

Product format: freeze dried,200ul

Validity period: 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 and can be used normally. Handling instructions of agar plate 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: 30°C, aerobic, YM medium, 2-3 days. YM medium: yeast extract 3.0g, malt extract 3.0g, glucose 10.0g, peptone 5.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L, pH 6.2±0.2. Sterilize at 121°C for 15min.

Recovery steps:

① Prepare 1-2 pieces of Blood agar plates;

②Open it in 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 liquid culture medium into the freeze dried ampoule,make the strain pellet fully dissolved and inoculate a plate with the solution, then distribute it well in 200ml/plate;

④ Put the agar plates under the above culture conditions for cultivation，2-3days.

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

Item	test results
viability:	good viability, in 3days strain layer become obvious;colony is typical on the streaked plate
colony morphology: (above)	size: 2-4mm ; Shape: round ; Edge: irregular ; Transparency: opaque color: white ; Protuberance: flat ; Surface: rough ; Texture: dry
Conclusion:	good viability, no abnormal colony morphology, qualified
