| Culture medium | BNCC352252 |
| Description | Brain Heart Infusion Agar |
| Composition | Beef Brain Infusion Powder:4.0g, Beef Heart Infusion Powder:4.0g, Peptone:5.0g, Casein Peptone:16.0g, NaCl:5.0g, Glucose:2.0g, Na2HPO4:2.5g, Agar:13.5g, pH:7.4±0.2(25℃) |
| Growth conditions | 37 ℃; 18-24h; aerobic |
| Subculture procedure | ① Prepare 1-2 of the above plates; ② After disinfecting the surface of the ampoule tube, open it in a safety cabinet, burn the top with an alcohol lamp, quickly drip sterile water to break it, and then use tweezers to crush it; ③ Take 0.5mL of sterile water and transfer it into a freeze-drying tube. After fully dissolving the bacterial powder, transfer it into a Agar plate at a rate of 200 μ L per piece and apply evenly; ④ Place the petri dish under the above cultivation conditions for cultivation, and once the bacterial strain grows, it can be used. |
| Storage conditions | 2-8 ℃ |
| Safety level | 1 |
| morphology | The colonies measure 0.5-1 mm in diameter, are circular with regular margins, and appear opaque. They exhibit a grayish-white coloration on the surface, with a raised center, and are smooth and moist in texture, making them easy to lift. The organisms are Gram-positive (G⁺, appearing blue-violet) and spherical (cocci). |
| Sharing mode | Public welfare sharing |
