1 Dissolve ingredients (except carbonate, ferrous iron sulfate, vitamins and organic substrates), 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 anoxic Hungate-type tubes or serum vials and autoclave. Add ferrous iron sulfate (dissolved in 0.1 N H2SO4), vitamins, pyruvate, fumarate and yeast extract from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas atmosphere. Stock solutions of ferrous iron sulfate, vitamins, pyruvate and fumarate should be sterilized by filtration. Adjust pH of the complete medium to 7.5, if necessary. | |||||
2 Note: Addition of 10 - 20 mg sodium dithionite per litre (e.g. from 5% (w/v) solution, freshly prepared under N2 and filter-sterilized) may stimulate growth at the beginning. |
