1 Dissolve ingredients except bicarbonate, succinate, vitamins, cysteine and sulfide, then sparge medium with 100% CO2 gas for 30 - 45 min to make it anoxic. Add the bicarbonate and equilibrate the medium with the CO2 gas to reach a pH between 6.5 and 7.0. Dispense medium under 100% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add succinate, vitamins, cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. The vitamin solution should be sterilized by filtration. Prior to use adjust pH of complete medium to 6.6 - 6.8, if necessary. |
