1 Dissolve ingredients, except sodium thiosulfate, then sparge solution with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Adjust pH to 7.0, then distribute medium under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials (e.g., 20 ml medium in 100 ml bottles) and autoclave. Prior to inoculation, add thiosulfate from an anoxic stock solution prepared under 100% N2 gas and sterilized by filtration. Adjust pH of complete medium to 7.0, if necessary. | |||||
2 After inoculation, pressurize culture vessels to 0.5 bar overpressure with sterile 100% H2 gas. |
