1 Dissolve ingredients except sulfur, yeast extract, vitamins and sulfide. Adjust pH to 3.5 with H2SO4 and sparge medium with 100% CO2 gas for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials containing the appropriate amount of sulfur. Heat vessels containing medium to 90°C for 1 hour on each of 3 succesive days. Add yeast extract, vitamins (sterilized by filtration) and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. The sulfide stock solution (3% w/v) should be neutralized before use (see medium 29). The pH of the complete medium should be at 3.5 - 3.8.

1 The sulfide solution is prepared in a 250 ml screw-capped bottle with a butyl rubber septum and a magnetic stirrer. The solution is bubbled with nitrogen gas, closed and autoclaved for 15 min. at 121°C. After cooling to room temperature the pH is adjusted to about 7.0 by adding of sterile 2 M H2SO4 drop-wise with a syringe without opening the bottle.
