1 Dissolve ingredients except sulfur, peptone, yeast extract, vitamins, 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 the same gas atmosphere into anoxic Hungate-type tubes or serum vials that already contain the appropriate amount of sulfur. Sterilize the medium by autoclaving at 110°C for 20 min. After sterilization add peptone, yeast extract, and vitamins from sterile stock solutions prepared under 100% N2 gas atmosphere and sulfide from a neutralized stock solution. Vitamins should be sterilized by filtration. |

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. |
