1 Dissolve ingredients (except bicarbonate, coenzyme M, vitamins, thiosulfate, and dithiothreitol), then sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under the same gas atmosphere into anoxic serum vials (e.g., Balch-type tubes) to 30% of their volume and autoclave. Add coenzyme M, vitamins, thiosulfate, and dithiothreitol from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas atmosphere. The vitamin and dithiothreitol solutions should be sterilized by filtration. Adjust the pH of the complete medium to 6.5. | |||||
2 After inoculation pressurize culture vessels to 1.5 bar overpressure with sterile 80% H2 and 20% CO2 gas mixture. |
