Clostridium novyi

Storage conditions: 2~8 ℃

No. 277828

Product format: freeze dried,200ul

Validity period: 6 years

Biosafety level: 2, handle in 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:37 ℃, anaerobic, Colombian blood plate (ready-to-use type),2-3 days.

Recovery steps:

(1) Prepare 1-2 of above mentioned plates（place in anaerobic environment for 24hours before usage）；

(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:

Item	test results
viability	good viability,in 2 days strain layer become obvious, colony is typical
colony morphology: (above)	size: 0.5-1mm shape: round edge: irregular transparency: opaque Color: off-white uplift: middle convex surface: bright and smooth texture: moist and easy to stir
Conclusion	good viability, no abnormal colony morphology, qualified
