1 Dissolve ingredients (except bicarbonate, vitamins, cysteine and sulfide) and sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Then add and dissolve bicarbonate, adjust pH to 6.8 and dispense medium under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. Cysteine and sulfide are autoclaved separately under 100% N2 gas atmosphere as concentrated stock solutions. Vitamins are prepared under 100% N2 gas atmosphere and sterilized by filtration. Appropriate volumes of the solutions are injected into the sterile medium with hypodermic syringes. Adjust pH of the complete medium to 6.8 - 7.0, if necessary.
Solution occurs in 263 other media (first defined in Medium 320).
