Subculture procedure	(1) Prepare 1-2 plates; (2) Open it in the safety cabinet, heat the tip of ampoule in a flame, quickly drop sterile water to creak it, then break it with forceps; (3) draw 0.5mL of sterile water into a freeze dried ampoule, fully rehydrate, inoculate a plate with the solution at 200ul/plate; (4) Put the plate under the above culture conditions for 18-24 hours.
Growth conditions	37 ℃,24-48h, anaerobic
Storage conditions	2-8 ℃
morphology	The colony diameter is 1-2mm, round, with neat edges, opaque, gray-white on the front, gray-white on the back, flat in shape, smooth in surface, bright in surface, moist in texture, easy to stir up, G-(red), bacilli, purity: pure
application	Quality control strain for API and BBL products. Control strain for anaerobe identification.
Sharing mode	Public welfare sharing

Bacteroides ovatus

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
