Dissolve ingredients (except bicarbonate, acetate, butyrate, vitamins, and sulfide) and sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate, adjust pH to 7.0, then dispense medium under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add acetate, butyrate, vitamins, and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. The vitamin solution should be sterilized by filtration. Before use, check the complete medium's pH and adjust it to 7.0 - 7.2, if necessary.
For DSM 2925: Replace acetate and butyrate with 1.00 g/l ethanol absolute added from a sterile anoxic stock solution after autoclaving.
For DSM 7213: Replace acetate and butyrate with 0.60 g/l Na-benzoate added after autoclaving from an anoxic stock solution sterilized by filtration.
For DSM 100382: Replace acetate and butyrate with 1.60 g/l Na-fumarate added after autoclaving from an anoxic stock solution sterilized by filtration.
