Preparation of Solution C: Add components to distilled/deionized
water and bring volume to 10.0mL. Mix thoroughly.
Preparation of Medium: Bring solution A to a boil for a few min-
utes. Cool to room temperature while gassing with oxygen-free N2 gas.
Add solutions B and C. Adjust pH to 7.8 with NaOH. Immediately dis-
tribute under N2 into anaerobic tubes. During distribution continuously
swirl the medium to keep the grey precipitate suspended. Autoclave for
15 min at 15 psi pressure–121°C.
Use: For the cultivation of Desulfovibrio giganteus (Desulfobacter
giganteus).
