Preparation
- Dissolve ingredients (except ferric chloride, cysteine, starch and sulfide), sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Add ferric chloride and solid cysteine, then adjust pH to 6.3. Dispense medium under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials (e.g., 20 ml medium in 50 ml bottles) and autoclave. Prior to inoculation add starch and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Adjust pH of complete medium to 6.5, if necessary.
- First dissolve nitrilotriacetic acid and adjust pH to 6.5 with KOH, then add minerals. Adjust final to pH 7.0 with KOH.
