Seawater salts – hydrostatic pressure effects upon cell division of several bacteria

An increased concentration of seawater salts increased the maximum hydrostatic pressure allowing cell division of the marine bacteria Achromobacter aquamarinus, Micrococcus sedentarius, Serratia marinorubra, and Vibrio adaptants. Increased concentrations of these salts did not have as great an influence on the maximum hydrostatic pressure for cell division of Escherichia coli and Micrococcus luteus, which were isolated from a terrestrial environment.
