A new algal strain Dunaliella salina Р 5 has been isolated in culture. Cells of the alga contain a complex of  biologically active substances preventing lipid peroxidation in tissues and blood serum and exerting favorable action on the biochemical processes in tissues. This algal culture is adapted to the laboratory conditions and shows application promise in the food, pharmaceutical and cosmetic industries and for balneological purposes.

Antioxidative activity of Dunaliella salina extract is higher than that of Haematococcus pluvialis extract. The substances from algal cells inhibit the growth of Escherichia coli and Pseudomonas aeruginosa and do not affect the normal microflora of intestine.

This algal culture is adapted to the laboratory conditions and shows application promise in the food,  pharmaceutical and cosmetic industries and for balneological purposes. Compared with the known foreign strains—Ukraine, Israel (Dead Sea), Western Australia (Pink Lake), USA (Great Salt Lake)—the new strain Dunaliella salina P5 is distinguished by culture and biology features.
