Enterobacter carcinogenes

Culture medium	Columbia blood plate (CA-B): casein pancreatin digest 10.0g, cardiopancreatin digest 3.0g, corn starch 1.0g, meat gastric enzyme digest 5.0g, yeast extract 5.0g, sodium chloride 5.0, agar 20.0g, distilled water 1.0L,pH 7.3±0.2. After sterilization at 121 ℃ for 15min, cool to 55 ℃, add 5% sterile defibrated sheep blood, shake well, pour the plate and cool it for later use.
Subculture procedure	(1) Prepare 2 plates (put them in anaerobic environment for deaeration 24 hours before handling); (2) sterilizing the ampoule, open it in biosafety 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 the freeze dried ampoule, make it fully dissolved, and distribute the solution to the plates well in 200ul/plate. (4) put the plate on the above culture conditions.
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, convex in the middle, bright surface, smooth surface, moist texture, easy to stir up, G-(red), bacilli
Separation substrate	Human arm wound, New York
Sharing mode	Public welfare sharing

Enterobacter cancerogenus

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),24-48h.

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（place in anaerobic environment for 24 hours before usage） 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 24-48 hours.

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

Item	test results
viability	good viability, in 24 hours strain layer become obvious, colony is typical
colony morphology: (above)	Size: 1-2mm Shape: Round Edge: Irregular Transparency: Opaque color: white bulge: middle bulge surface: bright and smooth texture: moist and easy to stir
Conclusion	good viability, no abnormal colony morphology, qualified
