1 Dissolve ingredients except carbonate, 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 carbonate, adjust pH to 7.2 then dispense medium under 80% H2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. Add vitamins (sterilized by filtration), cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Prior to use check pH of complete medium and adjust to 7.3 - 7.5, if necessary. | |||||
2 After inoculation add sterile 80% H2 and 20% CO2 gas mixture to 1.5 - 2 bar overpressure. |
