A pinch of salt

Methanonatronarchaeia are a distinct class-level lineage of extremely halophilic methanogens, which lack features of classical methanogenesis and have a high intracellular concentration of potassium, suggesting potassium-based osmoprotection.

Refers to "Discovery of extremely halophilic, methyl-reducing euryarchaea provides insights into the evolutionary origin of methanogenesis" by Sorokin et al.
