| Subculture | 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. |
| Subculturing | (1) Prepare the above two plates; (2) After disinfecting the surface of the ampoule tube, open it in a safety cabinet, burn the top with an alcohol lamp, quickly drop sterile water to break it, and then crush it with tweezers; (3) Absorb 0.5mL of sterile water (placed in anaerobic environment for 24 hours) into a freeze-drying tube, fully dissolve the bacterial powder, then punch into 2 plates, 200 μL/piece, and coat evenly; ④ Place the plate under the above culture conditions, and the strain can be used when it grows out. |
