1 Dissolve ingredients (except cysteine, glucose and thiosulfate), boil medium for 1 min, then cool to room temperature under 100% N2 gas atmosphere. Add cysteine and adjust pH to 7.0. Thereafter, dispense under100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. After autoclaving add glucose and thiosulfate from sterile anoxic stock solutions prepared under 100% N2 gas. Adjust pH of complete medium to 7.0, if necessary.
