Preparation
- Dissolve ammonium sulfate, potassium phosphate and trace elements, adjust pH to 5.2 using 10 N H2SO4 and 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 anoxic Hungate-type tubes or serum vials and autoclave. Add magnesium sulfate, calcium chloride, yeast extract, vitamins (sterilized by filtration), cysteine and ferrous chloride from sterile anoxic stock solutions prepared under 100% N2 gas. Adjust pH of complete medium to 5.0 - 5.2, if necessary.
- Adjust pH of final solution to 2 with 1 N HCl.
