GROWTH AND ACCUMULATION OF TOTAL CAROTENOIDS IN TWO STRAINS OF Dunaliella salina Teod. (CHLOROPHYCEAE) FROM THE NORTHERN AND CENTRAL COAST OF PERÚ

In order to know the dynamics of growth and accumulation of total carotenoids in two strains of Dunaliella salina from the northern (Colán) and central (Chilca) coast of Perú, both strains were cultured during 40 days in controlled laboratory conditions, at 25±2°C, with 150 mol m-2 s-1, without aere...
