The effect of elevated NaCl concentrations (0.5–4.0 M) on the proline content and activity of free peroxidase in green alga Dunaliella salina have been investigated. It was revealed that the tolerance of the alga to NaCl effect was determined by the functioning of the complex of metabolic reactions including both the necessary stress-induced accumulation of proline and high activity of the free peroxidase. The obtained data demonstrate testify to a deep reorganization of metabolic processes, occurring in alga cells during the adaptation to elevated salinity conditions.
