1 Dissolve ingredients except bicarbonate, ethylene glycol, vitamins, cysteine and sulfide, bring to the boil and cool to room temperature under 80% N2 and 20% CO2 gas mixture. Add bicarbonate (solid) and equilibrate the medium with the gas until a pH of around 7.4 is reached. Then distribute under the same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Before use add ethylene glycol, vitamins (sterilized by filtration), cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Adjust pH of complete medium to 7.0 - 7.2, if necessary.
Solution occurs in 166 other media (first defined in Medium 141).
