1 Dissolve ingredients (except bicarbonate, acetate and sulfide) and sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Then, add and dissolve bicarbonate, adjust pH to 8.5 - 9.0, dispense under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. After sterilization add acetate and sulfide from sterile anoxic stock solutions autoclaved under 100% N2 gas atmosphere. Adjust pH of complete medium to 8.5 - 9.0, if necessary. |
