Dispense the medium into suitable culture vessels under a stream of H2/CO2 (80/20), seal with butyl rubber stoppers, and autoclave at 121°C for 15 min. Separately autoclave Na2S·9H2O (5% solution) under N2 atmosphere. Sterilize vitamin and NaHCO3 solutions by filtration. Sulfur is sterilized separately by autoclaving for 60 min at 105°C on each of 3 successive days. Prior to inoculation, aseptically and anaerobically add vitamin, sulfur, NaHCO3, and Na2S·9H2O, and pressurize the inoculated vessels to 150 kPa with H2/CO2 (80/20). Final pH is 5.5-6.0. | | | | | | | | | | *Trace elements solution | | | | Nitrilotriacetic acid (NTA) | 12.8 | g | | | | FeCl3·6H2O | 1.35 | g | | | | MnCl2·4H2O | 0.1 | g | | | | CoCl2·6H2O | 0.024 | g | | | | CaCl2·2H2O | 0.1 | g | | | | ZnCl2 | 0.1 | g | | | | CuCl2·2H2O | 0.025 | g | | | | H3BO3 | 0.01 | g | | | | Na2MoO4·2H2O | 0.024 | g | | | | NaCl | 1 | g | | | | NiCl2·6H2O | 0.12 | g | | | | Na2SeO4 | 0.8 | mg | | | | Na2WO4 | 0.8 | mg | | | | KAl(SO4)2·12H2O | 4 | mg | | | | Distilled water | 1 | L | | | | First dissolve nitrilotriacetic acid and adjust pH to 6.5 with NaOH, and then add minerals.
