Bacteroides ovatus Eggerth and Gagnon

Subculture procedure	① Dissolve the frozen tube in a water bath (37 ℃ for bacteria) and shake quickly to dissolve; ② Wipe the outer wall of the Frozen vial with an alcohol swab for disinfection, and then transfer it to a safe cabinet for operation; ③ Unscrew the tube cap, aspirate all the dissolved solution, and transfer it into 1-2 agar plates (each Agar plate contains approximately 200 μ L, and for anaerobic bacteria cultivation, the culture medium needs to be placed in an anaerobic environment for 24 hours to remove oxygen); ④ After uniform coating, transfer to the above cultivation conditions for cultivation.

Bacteroides ovatus

Storage conditions: 2~8 ℃

No. 260545

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).

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 until there grow.

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

item	test result
viability	good viability,in 5 days strain layer become obvious, colony is typical
colony morphology: (above)	size: 1-2mm shape: round edge: neat transparency: opaque color: off-white bulge: middle convex surface: bright and smooth texture: moist and viscous
Conclusion	good viability, no abnormal colony morphology, qualified
