A red, obligately halophilic Dunaliella species believed to be D. salina was isolated from the North Arm of the Great Salt Lake, Utah, and its optimum growth conditions were determined.
The red pigmented Dunaliella species required an optimum NaCl concentration of 10%, temperature 28°C, and an illuminance of 7500 lux. Ammonium carbonate was preferred over potassium nitrate and ammonium chloride. Potassium nitrate was preferred over ammonium chloride. The average division (generation) time under the above conditions was 46.5 hours.
The alga grown in ammonium carbonate showed a lower content of chlorophyll a compared to those grown in potassium nitrate and in amonium chloride. The concentration of carotenoids of the alga grown in ammonium carbonate was higher than those in potassium nitrate and in ammonium chloride.
