1 Dissolve ingredients except carbonate, pyruvate, vitamins, thiosulfate and sulfide, then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 minto make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add pyruvate, vitamins, thiosulfate and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Stock solutions of pyruvate, vitamins and thiosulfate should be sterilized by filtration. Prior to use adjust pH of complete medium to 7.3 - 7.5, if necessary. |
