1 Dissolve ingredients (except sulfur, bicarbonate, yeast extract, vitamins and sulfide) and sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic serum vials (e.g., Balch-type tubes) containing already the appropriate amount of sulfur, only to 30% of their volume to allow for a large headspace. Autoclave at 110°C for 20 min. Add yeast extract, vitamins and sulfide form sterile anoxic stock solutions prepared under 100% N2 gas and bicarbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. The vitamin solution should be sterilized by filtration. Adjust pH of the complete medium to 7.0-7.2. | |||||
2 After inoculation pressurize vessels with sterile 80% H2 and 20% CO2 gas mixture to 2 bar overpressure. |
