1 Dissolve ingredients (except yeast extract, Casamino acids, vitamins, carbonate, hydrogenphosphate and sulfide), bring medium to the boil, then cool to room temperature under 80% N2 and 20% CO2 gas mixture. Dispense under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. After sterilization add yeast extract, Casamino acids, hydrogenphosphate 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. Vitamins are prepared under 100% N2 gas atmosphere and strerilized by filtration. Adjust pH of complete medium to 7.0, if necessay.
