Comments Escherichia coli grows over more than a hundred-fold range of external osmolality (Osm), extending from as low as 0.015 Osm (Baldwin et al., 1995) up to 1.9 Osm (McLaggan et al., 1990 Cayley et al., 1991) in minimal medium and up to 3.0 Osm in rich medium (Record et al., 1998a). For osmolality range of 0.005Osm to 3Osm see PMID 22514721 p.1 left column top paragraph
