1 Dissolve ingredients (except sulfur, glucose, vitamins and sulfide), then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Adjust pH to 6.2 - 6.4 and dispense medium under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials containing already the appropriate amount of sulfur. Sterilize medium by heating cultivation vessels in a boiling water bath for 2 - 3 hours on each of 3 successive days. After sterilization add glucose, vitamins and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere. Vitamins are sterilized by filtration. Adjust pH of complete medium to 6.5, if necessary.
