Mix components, except NaHCO3, and adjust pH 7.0. Bring to a boil for 5-10 seconds, then, cool down under a stream of H2-CO2 (80:20 v/v) and add NaHCO3. Dispense the medium into suitable culture vessels (e.g., 20 ml in 120 ml serum bottles) under a stream of H2-CO2 (80:20 v/v), seal with butyl rubber stoppers and autoclave. Aseptically and anaerobically add per liter the following solutions (autoclaved or filter-sterilized, and stored under a N2 atmosphere):
Trace vitamins* (see Medium No. 197)  2.0     ml
