1 Dissolve ingredients (except carbonate, glucose, maltose, cellobiose, soluble starch, cysteine and sulfide), then sparge medium with 100% CO2 gas for 30 - 45 min to make it anoxic. Add the carbonate and equilibrate the medium with the CO2 gas to pH 6.8. Distribute under 100% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Thereafter, add glucose, maltose, cellobiose, soluble starch, cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere. Adjust pH of complete medium to 6.7 - 6.8, if necessary.
