Protocol Notes
- Inject 1 mL of sterile DI water into vial and gently mix.
- Use small portions of vial (liquid) contents to inoculate a sterile, liquid culture to an initial OD of 0.03-0.1. For this liquid culture, use the specified growth medium with or without an antibiotic as appropriate.
- When culture has visibly grown in liquid medium, plate on solid (Agar) growth medium and incubate at 37C. Maintain strain.
