| Culture medium | BNCC352241 |
| Description | Columbia blood agar plate |
| Composition | Special Peptone:23.0g, Soluble Starch:1.0g, NaCl:5.0g, Agar:10.0g, Defibrinated Sheep Blood:5%(added at 50℃), pH:7.3±0.2(25℃) |
| Growth conditions | 37 ℃; 48-72 hours; anaerobic |
| Subculture procedure | ①Prepare 1-2 fresh agar plates (placed in an anaerobic environment for 24 hours of deoxygenation) with typical bacterial colonies; ② Open the 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 liquid culture medium or sterile water (placed in an anaerobic environment for 24 hours of deoxygenation in advance) and transfer it into a freeze-drying tube. Dissolve it thoroughly and mix well; ④ Transfer 0.2mL of bacterial suspension into a Agar plate, apply evenly, and repeat twice to obtain two plates; ⑤ Cultivate under the above conditions, and the strain can be used once it grows. |
| Storage conditions | 2-8 ℃ |
| Safety level | 2 |
| morphology | Colonies measured 0.5-1 mm in diameter, exhibiting a circular form with an entire margin. They were opaque, grayish-white in color, and convex in elevation. The surface appeared smooth, glistening, moist, and was easily liftable. Microscopic examination revealed Gram-negative (red), rod-shaped cells, and the culture was confirmed to be pure. |
