The extremely halophilic bacterium Salicola marasensis IC10 accumulates the compatible solute betaine.
The extremely halophilic bacterium strain IC10 was isolated from a solar saltern on Isla Cristina (southern Spain). Phylogenetic, genotypic and phenotypic data supported the inclusion of this strain in the species Salicola marasensis. An analysis of intracellular organic osmotic solutes showed glycine betaine to be present, contributing to the overall osmotic balance, and this was the only compatible solute accumulated when S. marasensis IC10 was grown over a wide range of external NaCl concentrations (10-25%, w/v).
