Preparation
- Dissolve ingredients (except bicarbonate, vitamins, methanol, cysteine and sulfide) and sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Then add and dissolve bicarbonate, adjust pH to 6.5 and dispense medium under 80% N2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. Methanol (50% v/v stock solution) and the reducing agents are each autoclaved separately under 100% N2 gas atmosphere as concentrated solutions in tightly closed tubes. Vitamins are prepared under 100% N2 gas atmosphere and sterilized by filtration. Appropriate volumes of the stock solutions are injected into the sterile medium with hypodermic syringes. Adjust pH of the complete medium to 6.8 - 7.0, if necessary.
- The ferrous sulfate solution is not stable and should be freshly prepared.
- First dissolve FeCl2 in the HCl, then dilute in water, add and dissolve the other salts. Finally make up to 1000.00 ml.

- Description
- Slow-growth phase condition for Methanosarcina acetivorans on Methanosarcina Medium.
- Modifications
- Capture slow-growth phase physiology separately from faster growth conditions.
- Use Methanosarcina acetivorans as the target organism.
- Purpose
- Represent growth-phase-specific doubling time evidence without creating a separate medium record.

- Snippet
- M. acetivorans was found to be polyploid during fast growth (t(D) = 6 h; 17 genome copies) and oligoploid during slow growth (doubling time = 49 h; 3 genome copies).
- Explanation
- Literature evidence supports modeling the slow-growth phase as a condition variant under the parent Methanosarcina Medium record.
