1 Dissolve ingredients except bicarbonate, cysteine and sulfide. Sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate, adjust pH to 6.8 and dispense medium under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Prior to use check pH of complete medium and adjust to 6.8 - 7.0, if necessary.
Solution occurs in 262 other media (first defined in Medium 320).

1 Add 0.4% yeast extract to sludge from an anaerobic digester, and after gassing with nitrogen gas for a few minutes incubate it at 37°C for 24 hours. Then centrifuge the sludge at 13000 g and autoclave the resulting, clear supernatant in screw-capped vessels under nitrogen gas. The sludge fluid can be stored at room temperature in the dark.
