| 1 Dissolve ingredients (except carbonate, pyrosulfite and vitamins), then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into Hungate-type tubes or serum vials and autoclave. Add pyrosulfite from a 10% (w/v) stock solution adjusted to pH 7.5-8.0 with NaOH, made anoxic with 100% N2 gas and sterilized by filtration. Vitamins are added from a stock solution prepared under 100% N2 gas atmosphere and sterilized by filtration and carbonate is added from a sterile stock solution prepared under 80% N2 and 20% CO2 gas atmosphere. Adjust pH of complete medium to 7.5 - 8.0. Incubate without shaking. | |||||

| 1 Slowly titrate 320 ml of a FeCl3 x 6 H2O stock solution (60.00 g/l) with 10% (w/v) NaOH to pH 8.0-8.5 under agitation (use magnetic stirrer). Total amount of added NaOH approx. 80 - 100 ml. The precipitated Fe(OH)3 should be stored at room temperature overnight with surface covered with water. Thereafter, centrifuge at 2000 rpm for 5 min and discard the supernatant. Wash several times with distilled water. Resuspend the pellet in medium as described above. For storage autoclave under 100% N2 atmosphere. | |||||
