| Culture medium | BNCC352239 |
| Description | Nutrient Agar |
| Composition | Peptone:10.0g, Beef Extract Powder:3.0g, NaCl:5.0g, Agar:15.0g, pH:7.3±0.1(25℃) |
| Growth conditions | 30°C; 24-48h; aerobic |
| Subculture procedure | ① Prepare 1 test tube containing 5–10 mL liquid medium and 2 plates; ② Open in a safety cabinet, cauterize the top with an alcohol lamp, then quickly add sterile water to shatter it; break into pieces with forceps; ③ Pipette 0.5 mL liquid medium into the freeze-dried vial, dissolve completely, then return to the liquid test tube and mix thoroughly; ④ Pipette 0.2 mL of the bacterial suspension onto a Agar plate and spread evenly. Repeat twice to obtain two plates; ⑤ Incubate all liquid tubes and plates under the specified conditions. The culture is ready for use once the strain grows. |
