Preparation
- Mix components thoroughly, and autoclave under a N2-CO2 (80:20, v/v) gas atmosphere. After cooling, aseptically and anaerobically add the following solutions (filter-sterilized):
- Distribute the medium into culture vessels (leave >80% gas phase by volume) under a H2-CO2 (80:20, v/v) gas mixture, seal with butyl rubber stoppers. Finally, add per liter the following solutions from anaerobic stocks (autoclaved and stored under a N2 atmosphere):
- Pressurize the inoculated vessels to 200 kPa H2-CO2 (80:20, v/v).
- Dissolve nitrilotriacetic acid and adjust pH to 6.5 with KOH. Then proceed to add minerals. Adjust final pH to 7.0.
