Preparation
- Add components except L-cysteine x HCl x H2O and FeCl2 x 4H2O to distilled water, bring volume to 1.0 L and adjust pH to 7.0. Distribute the medium into appropriate culture vessels (e.g., 20 ml of the medium in 120 ml serum bottles) under a H2-CO2 (4:1, v/v) gas mixture, sparge with the same gas mixture for 10 - 15 min, seal with butyl rubber stoppers and autoclave. Separately autoclave concentrated (100- or 200-fold) L-cysteine x HCl x H2O and FeCl2 x 4H2O solutions under a N2 gas atmosphere. Prior to inoculation, add the sterile L-cysteine x HCl x H2O and FeCl2 x 4H2O solutions. Pressurize the inoculated vessels to 100 kPa H2-CO2 (4:1, v/v) and cultivate without shaking.
- Comment: For strain JCM 12379, inoculate with a 10% inoculum.
- Dissolve 108 g FeCl3 in 1.0 L distilled water. Adjust pH to 7.0 with 10 N NaOH. Allow the suspension to sit for 30 min, then readjust pH to 7.0. Centrifuge the suspension at 5,000 x g for 20 min and pour off supernatant. Wash the precipitate with distilled water by resuspending in distilled water followed by the centrifugation. Repeat the washing at least 5 times, then, resuspend in 1.0 L distilled water. Use the Fe(III) suspension as 0.67 M solution. More precisely, check the concentration of Cl- to be less than 1 mM and determine the concentration of Fe(III) by using hydroxylamine as described by Lovley and Phillips (Appl. Environ. Microbiol. 54, 751-757, 1986).
- Use Trace minerals of Medium No. 151 supplemented with 0.025 g (final) Na2MoO4 x 2H2O, 0.024 g NiCl2 x 6H2O and 0.025 g Na2WO4 x 2H2O (per liter).
- Comment: For strain JCM 12378, inoculate with a 10% inoculum.
