1 Dissolve ingredients except sulfur and sulfide, adjust the pH to 6.5, and sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Distribute medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials that contain already the appropriate amount of sulfur. Sterilize medium by heating cultivation vessels in a boiling water bath for 1 - 2 hours on each of 3 successive days. Add sulfide from a neutralized stock solution (see medium 29) prepared under 100% N2 gas atmosphere.
Solution occurs in 166 other media (first defined in Medium 141).
