| Subculture procedure | ① Prepare 1-2 fresh agar plates as specified above (pre-conditioned in an anaerobic environment for 24 h to remove oxygen).② Working in a biosafety cabinet, open the vial and briefly flame the top with an alcohol burner. Immediately add sterile water to break the seal, then crush the vial using sterile forceps.③ Aspirate 0.5 mL of liquid medium or sterile water (pre-conditioned in an anaerobic environment for 24 h to remove oxygen) into the freeze‑dried vial, thoroughly dissolve the contents, and mix well.④ Transfer 0.2 mL of the resulting bacterial suspension onto an agar plate, spread evenly, and repeat to inoculate a second Agar plate.⑤ Incubate the plates under the designated culture conditions. The strain is ready for use once growth appears. |
