Sneathia sanguinegens

Culture medium	Columbia blood plate (English name: 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 a test tube containing 5~10mL of liquid medium and 2 plates; (2) open it in the biosafety cabinet, heat the tip of ampoule in the flame, quickly drop sterile water to creak it, and break it with forceps; (3) draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; (4) inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; ⑤ Put all the liquid test tubes and plates under the above culture conditions for cultivation, and the strains can be used when they grow.
Growth conditions	37 ℃;2-3 days; Anaerobic
Storage conditions	2-8 ℃
morphology	Colony diameter of 1-2mm, irregular shape, irregular edge, opaque, gray-white front, flat shape, dark surface, dry texture, G-(red), bacilli, purity: pure
Sharing mode	Public welfare sharing

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 plate 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, 2-3 days, Columbia blood plate (ready-to-use type).

Recovery steps:
(1) Prepare 1-2 of above mentioned plates(put in an anaerobic environment for deoxygenation in advance for 24 hours);
(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:
