1 Dissolve ingredients (except cysteine, glucose and vitamins), sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Add cysteine and adjust pH to 6.0, then dispense medium under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Prior to inoculation add glucose and vitamins from sterile anoxic stock solutions prepared under 100% N2 gas. The vitamin solution should be sterilized by filtration. Adjust pH of complete medium to 6.0, if necessary.
