1 Sparge solution A with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic and reach a pH of around 6, then distribute under the same gas atmosphere into anoxic Hungate-type tubes and autoclave. Solutions B and C are prepared under 100% N2 gas atmosphere and sterilized by filtration. Solutions D and F are autoclaved separately under 100% N2 gas. Solution E is prepared under 80% N2 and 20% CO2 gas gas atmosphere. To complete the medium appropriate amounts of solutions B to F are added to the sterile solution A in the sequence as indicated. Final pH of the medium should be at 7.0. After combining solutions the medium should equilibrate overnight and a white precipitate should be apparent.
2 Note: Addition of 10 - 20 mg sodium dithionite per liter (e.g. from 5% (w/v) solution freshly prepared under N2 and filter-sterilized) just before inoculation may stimulate growth at the beginning. For transfers use 5 - 10% (v/v) inoculum.
