Abstract

In this study, some of the growth parameters and biochemical composition of Chaetoceros muelleri were investigated under blue, white, and red light. Different treatments of lights applied to Chaetoceros muelleri cultures (salinity 25 ppt, temperature 23 ± 1° C, light intensity 1500 ± 200 lux, Light/Dark 12/12, mild aeration, alkalinity 7. 5-8. 5( for 12 days in divided Indoor chambers. The microalgae under blue light showed the highest cell density, specific growth rate, Chlorophyll a, dry weight, Protein, omega-3 Fatty Acids, palmitoleic acid (C16: 1), and the shortest doubling time, low fat and omega-6 were observed. The lowest cell density, dry weight, Chlorophyll a, Protein, omega-3 Fatty Acids, oleic acid (C18: 1), and more than 25% palmitic acid (C16: 0) were observed under red light. The highest doubling time of the population, the highest amount of omega-6 Fatty Acids and oleic acid (C18: 1), was observed in white light. The total fat content was not significantly different between the three light ones (p <0. 05). Red light accounted for more than 41% of the SFA value, white light more than 16% of PUFA, and light blue 46% of MUFA. Blue light clearly showed better performance and had a significant difference (0. 05 pp) compared to white and red while there was no significant difference between white and red.
