Mix ingredients and adjust pH to 6.8 with NaOH. Distribute the solution into culture vessels (leaving more than 80% volume of gas phase in the vessel) under a stream of a N2-CO2 (80:20, v/v) gas mixture, seal with butyl rubber stoppers and autoclave. Then, add the following solutions (filter-sterilized) to the medium (per liter):
Trace vitamins (see Medium No. 197)  1.0     ml
5% NaHCO3 solution  20.0     ml
Finally, replace the gas phase with a N2-CO2-O2 (79:20:1, by volume) gas mixture and pressurize to 200 kPa with the same gas mixture.
