1 Dissolve ingredients (except carbonate, thiosulfate, magnesium chloride, cysteine and sulfide), then 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 Hungate-type tubes or serum vials to 30% of their volume and autoclave. Add magnesium chloride, cysteine and sulfide 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 mixture. Adjust pH of the complete medium to 6.8 - 7.0, if necessary. | |||||
2 After inoculation pressurize cultivation vials to 1 bar overpressure with sterile 80% H2 and 20% CO2 gas mixture. |
