1 Dissolve ingredients of solution A except carbonate, sparge with 100% N2 gas for 30 - 45 min to make it anoxic, then add carbonate and adjust pH to 9.0 - 9.3. Dispense under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials (e.g., 30 ml medium per 100 ml bottle) and autoclave. Solutions B and C are autoclaved separately under 100% N2 gas atmosphere. Solutions D and E are prepared under 100% N2 gas and sterilized by filtration. To complete the medium add appropriate amounts of solutions B to E to the sterile solution A in the sequence as indicated. Adjust pH of complete medium to 7.5. | |||||
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) may stimulate growth at the beginning. | |||||
3 For transfers use 10% (v/v) inoculum. |
