1 Dissolve ingredients except carbonate, cellobiose, vitamins, cysteine and sulfide, then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 – 45 min to make it anoxic. Dispense medium under the same gas atmosphere into anoxic Hungate-type tubes and autoclave. Add cellobiose, vitamins, cysteine 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. Cellobiose and vitamins have to be sterilized by filtration. Prior to use adjust pH of complete medium to 7.2 - 7.4. Cellulose (MN 300, Whatman CF II, Kleenex tissue paper, or HCl treated cotton) can be used as an alternative to cellobiose. |
