1 Mix components thoroughly, adjust pH to 7.0 with KOH and autoclave under a N₂-CO₂ (4:1, v/v) gas mixture. After cooling, add the following solution from an anaerobic stock [filter-sterilized and stored under N₂-CO₂ (4:1, v/v)]:
NaHCO₃ (8%)	25.00	ml	-	-
2 Aseptically distribute the medium into culture vessels under a stream of N₂-CO₂ (4:1, v/v) and seal with butyl rubber stoppers. Prior to inoculation, add per liter the following solution from an anaerobic stock (autoclave and store under a N₂ atmosphere):
Na₂S x 9 H₂O (5%)	8.00	ml	-	-
