1 Mix components and adjust pH to 7.2 with 1.0 N KOH. Bring to a boil and cool down under a N₂ gas stream. Then, distribute the medium into culture vessels (e.g., 5 ml of the medium in the Hungate tubes) under a N₂-CO₂ (4:1, v/v) gas mixture, seal with butyl rubber stoppers and autoclave. Aseptically and anaerobically add the following solutions (filter-sterilized or *autoclaved) into the medium (per liter):
NaHCO₃ (8%)	25.0	ml	-	-
L-Cysteine x HCl x H₂O solution (*)	10.0	ml	-	-
Na₂S x 9 H₂O (*, 5%)	8.0	ml	-	-
