Official DSMZ medium: This medium was manually curated by experts from the DSMZ.
* Modification: Omit Trypticase peptone and fumarate. Increase amount of yeast extract to 2.0 g/l and supplement medium with 0.2 g/l Na-acetate and 0.6 g/l DL-lactate added after autoclaving from sterile anoxic stock solutions prepared under 100% N2 gas.

1 Dissolve ingredients (except sulfur, cysteine, peptone, fumarate, carbonate and sulfide) and sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissove cysteine, then dispense under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials containing already the appropriate amount of sulfur and autoclave at 121°C for 20 min. Add peptone, fumarate 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. Adjust pH of the complete medium to 7.0. |
