1 Dissolve ingredients (except bicarbonate, magnesium sulfate, calcium chloride, glucose, vitamins, cysteine and sulfide), then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate, adjust pH to 7.0, dispense under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. After sterilization add magnesium sulfate, calcium chloride, glucose, cysteine and sulfide from sterile anoxic stock solutions autoclaved under 100% N2 gas. Vitamins are prepared under 100% N2 gas atmosphere and sterilized by filtration. Adjust pH of the complete medium to 7.0 - 7.2, if necessary.
Solution occurs in 263 other media (first defined in Medium 320).
