The objective was evaluate the carotenogenic activity of Dunaliella salina isolated from the artificial salt flats of municipality of Manaure (Department of La Guajira, Colombia).
Two experimental testings were designed, in triplicate, to induce the reversibility of the cell tonality depending on the culture conditions.
In the first test (A), to induce the reversibility from green to red tonality in D.
salina cells, these were cultured in J/1 medium at a concentration of 4.0 M NaCl, 390 µmol m−2 s−1, 0.50 mM KNO3.
In the second test (B), to induce the reversibility from red to green cell tonality, the cultures were maintained in J/1 medium 1 M NaCl, 190 µmol m−2 s−1, 5.0 mM KNO3 and pH 8.2.
The population growth was evaluated by cell count and the pigment content was performed by spectrophotometric techniques.
It was found that in both tests the culture conditions influenced the population growth and the pigments production of D.
salina.
There was a significant difference between the mean values of total carotenoids in the test A with 9.67 ± 0.19 μg/ml and second test with 1.54 ± 0.08 μg/ml at a significance level of p < 0.05.
It was demonstrated that the culture conditions of test A induce the production of lipophilic antioxidants, among these carotenoids.
The knowledge of the stressful conditions for the production of carotenoids from D.
salina isolated from artificial saline of Manaure opens a field in implementation of this biotic resource for biotechnological purposes, production of new antibiotics, nutraceuticals and/or biofuels production.
