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:37 ℃, strictly anaerobic, Colombian blood plate (ready-to-use type),48-72h.

Recovery steps:
(1)Prepare 1-2 of above mentioned plates;
(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 for cultivation for 48-72 hours.

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

item	test result
viability	good viability, in 48-72h strain layer become obvious, colony is typical on the streaked plate
colony morphology: (above)	size: 1-2mm shape: round edge: irregular transparency: opaque color: white bulge: middle convex surface: bright and smooth texture: moist and viscous
Conclusion	good viability, no abnormal colony morphology, qualified
