Terrestrial Environment

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.

Translational Ambiguity

Hydrostatic pressure has been shown to inhibit protein synthesis in Escherichia coli by inhibiting amino acid activation and polypeptide synthesis in cell-free systems. Pressure may decrease translational ambiguity by suppressing any non-specific activity of phenylalanyl-tRNA synthetase and by preferentially decreasing the stability of leucyl-tRNA.
