Sneathia sanguinegens

Subculture procedure	Prepare 1-2 of the above plates (placed in an anaerobic environment for 24 hours of deoxygenation in advance) with typical bacterial colonies; 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 (placed in an anaerobic environment for 24 hours of deoxygenation in advance) and transfer it into a freeze-drying tube. After fully dissolving the bacterial powder, transfer it into a Agar plate 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.

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:37 ℃, anaerobic, 2-3 days, Columbia blood plate (ready-to-use type).

Recovery steps:
(1) Prepare 1-2 of above mentioned plates(put in an anaerobic environment for deoxygenation in advance for 24 hours);
(2) Open 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 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, and the strains can be used when they grow.
Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:

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, the colony is typical
colony morphology: (above)	size: 1-2mm Shape: round Edge: irregular Transparency: opaque color: off-white ; Uplift: flat ;Surface: gray ; Texture: dry
Conclusion:	good viability, no abnormal colony morphology, qualified
