1 Mix components thoroughly, except NaHCO3, and adjust pH to 7.0. Bring to a boil for a seconds, cool down under a stream of N2-CO2 (80:20, v/v) and add NaHCO3 to the medium. Dispense the medium into culture vessels (e.g., 20 ml in 120 ml serum bottles) under a H2-CO2 (80:20, v/v) gas mixture, seal with butyl rubber stoppers and autoclave. Aseptically and anaerobically add per liter the following solutions (autoclaved or filter-sterilized, and stored under N2):
