Preparation
- Dissolve all ingredients except Na-terephthalate, Na2S·9H2O, and cysteine-HCl up to 900 ml.
- Flush with N2/CO2 (80/20), then autoclave.
- Filter-sterilize Na2S·9H2O, cysteine-HCl, and neutralized 0.2 M Na-terephthalate solutions separately.
- Add filter-sterile Na2S·9H2O, cysteine-HCl, and neutralized Na-terephthalate solutions to each vial separately.
