| 1 Sparge solution A with 100% N2 gas for 30 - 45 min to make it anoxic, then distribute under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Solutions B and H are autoclaved separately under 100% N2 gas. Solutions C, E, F and G are prepared under 100% N2 gas and sterilized by filtration. Solution D is autoclaved under 80% N2 and 20% CO2 gas atmosphere. To complete the medium appropriate amounts of solutions B to H are added to the sterile solution A in the sequence as indicated. Adjust pH of complete medium to 7.3 - 7.6, if necessary. | |||||
| 2 Note: Before inoculation, the medium must be completely reduced, i.e. resazurin must be colorless. The addition of 10 - 20 mg sodium dithionite per liter (e.g. from 5% (w/v) solution, freshly prepared under N2 and filter-sterilized, see medium 829) can help to reduce the medium. | |||||
