Preparation
- Mix ingredients except Na2S2O3 x 5H2O, yeast extract, Trace vitamins and 2-mercaptoethanol, and adjust pH to 6.0. Bring to a boil for 5-10 sec, then, cool down under a stream of H2-CO2 (80:20, v/v). Dispense the medium into suitable culture vessels under a stream of H2-CO2 (80:20, v/v), seal with butyl rubber stoppers and autoclave 115C for 40 min. Separately autoclave Na2S2O3 x 5H2O and 2-mercaptoethanol as 50 g/L solutions and yeast extract as 100 g/L solution under a N2 atmosphere. Filter-sterilize Trace vitamins and store under a N2 atmosphere. Prior to inoculation, aseptically and anaerobically add the Na2S2O3 x 5H2O, yeast extract, Trace vitamins and 2-mercaptoethanol solutions to the medium. Pressurize the inoculated bottles to 200 kPa H2-CO2 (80:20, v/v).
- Dissolve nitrilotriacetic acid and adjust pH to 6.5 with KOH. Then proceed to add minerals. Adjust final pH to 7.0.
- Dissolve 0.2 g of Fe(NH4)2(SO4)2 x 6H2O in 5 ml of distilled water containing 2 drops of concentrated HCl. When the Fe(NH4)2(SO4)2 x 6H2O crystal have dissolved, bring volume up to 100 ml.
