| 1 Dissolve ingredients except cysteine, carbonate, trimethylamine and sulfide, bring medium to the boil, then cool to room temperature while sparging with 80% N2 and 20% CO2 gas mixture. Add cysteine and adjust pH to 6.5, then dispense under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Thereafter, add trimethylamine 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 complete medium to 7.3 - 7.4, if necessary. | |||||
