Preparation
- Dissolve ingredients (except glucose and cysteine), boil medium for 1 min, then cool to room temperature under a N2 gas atmosphere. Add cysteine and adjust pH to 7.0. Thereafter, dispense into culture vessels under a N2 gas atmosphere and autoclave. After autoclaving, add glucose from a sterile, anoxic stock solution prepared under a N2 gas atmosphere.
