Effect of Different LED Light Sources on Growth and Pigment Composition of Dunaliella salina Teodoresco (Chlorophyceae)

Abstract

In this study, the effects of red, blue, and yellow LED lights on cell number, growth rate, pigment, and crude oil contents of the green algae, Dunaliella salina Teodoresco, isolated from Ayvalık (Balıkesir) saltworks, were investigated. The highest cell number and growth rate were found algae grown in the red LED treatment as 335.3 x 104 cell ml-1 and 4.30 days-1, respectively. The highest chlorophyll a and β-carotene contents of Dunaliella salina cells were determined in the control group as 10.70 and 3.49 mg l-1, respectively. The highest crude oil content was determined as 18% in the yellow LED treatment. Our results showed that LED lamps positively affect the growth and biochemical composition of Dunaliella salina.
