1 Dissolve ingredients (except carbonate, vitamins, cysteine 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 Hungate-type tubes or serum vials and autoclave. Add vitamins, 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. The vitamin solution should be sterilized by filtration. Adjust pH of complete medium to 6.8, if necessary. After inoculation pressurize vials to 1 bar overpressure with sterile 80% H2 and 20% CO2 gas mixture.
Solution occurs in 170 other media (first defined in Medium 141).
