Mix components except NaHCO3 and bring to a boil for a few seconds. After cooling down under a stream of N2-CO2 (80:20, v/v), add NaHCO3 to the medium. Dispense the medium into culture vessels (e.g., 20 ml of the medium in 120 ml serum bottles) under the same gas mixture, seal with butyl rubber stoppers and autoclave. Allow to stand the medium until re-dissolved. Then, add per liter the following solutions (autoclaved or *filter-sterilized):
Trace vitamins* (see Medium No. 197)  10.0     ml
50% (v/v) Methanol  10.0     ml
5% L-Cysteine·HCl·H2O solution  10.0     ml
5% Na2S·9H2O solution  10.0     ml
