1 Dissolve ingredients (except bicarbonate, methanol, vitamins, cysteine and sulfide), then sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate and adjust pH to 7.0, then distribute under 80% H2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. After sterilization add methanol (50% v/v), vitamins, cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere. Vitamins are sterilized by filtration. Adjust pH of complete medium to 7.0 - 7.2. | |||||
2 After inoculation, pressurize culture bottles with sterile 80% H2 and 20% CO2 gas mixture to 2 bar overpressure. |
