1 Dissolve ingredients (except sulfur, carbonate, formate, vitamins and sulfide), then sparge medium with 80% N2 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 that contain already the appropriate amount of sulfur. For sterilization heat cultivation vessels for 1 - 2 hours to 90 - 100°C in a water bath on each of three successive days. Prior to inoculation add carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas atmosphere and formate, vitamins and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Vitamins are sterilized by filtration. Adjust pH of complete medium to 6.8, if necessary. |
