1 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. |
