The methanogenic Archaea, like the Bacteria and Eucarya, possess several osmoregulatory strategies that enable them to adapt to osmotic changes in their environment. The physiological responses of Methanosarcina species to different osmotic pressures were studied in extracellular osmolalities ranging from 0.3 to 2.0 osmol/kg. Regardless of the isolation source, the maximum rate of growth for species from freshwater, sewage, and marine sources occurred in extracellular osmolalities between 0.62… CONTINUE READING
