| 1 Dissolve ingredients of solution A, bring to the boil, then cool to room temperature while sparging with 100% N2 gas. Add solutions B and C, adjust pH to 7.8 with NaOH, and distribute under 100% N2 gas atmosphere into anoxic Hungate-type tubes. During distribution continuously swirl the medium to keep the grey precipitate suspended. Autoclave 15 min at 121 °C. Adjust pH of the complete medium to 6.8 - 7.0, if necessary. | |||||
