The effect of different light colors on the growth of Nannochloropsis sp.
Abstract
The purpose of this study was to determine the effect of different light colours on population density, relative growth and self-replication time in Nannochloropsis sp. This study used a completely randomized design experiment involving 5 treatments and 4 replications. Treatment A uses red light, treatment B uses yellow light, treatment C uses green light, treatment D uses blue light, and treatment E uses white light. Density observations were made every 36 hours. The results of the study showed that differences in the colour of light had a significant effect on population density and relative growth of Nannochloropsis sp. but no significant effect on self-replication time.
