Although Korean climate condition cannot provide steady light condition for outdoor culture of algal, utilization of sun light energy still has numerous benefits. Therefore, it is necessary to investigate how to maximize the efficiency of solar energy utilization by supplementing minimal amount of artificial light. Night Biomass Loss (NBL) was measured under natural conditions without supplying artificial light during night time. The results have shown that NBL quantity under natural condition was 30% higher than under continuous light condition which was illuminated by sun light during the day and by artificial light at night. In order to reduce NBL, artificial light was provided during night time and effect of intermittent light was investigated by changing the intermittent light time with 30, 60, and 150 minutes with light and dark ratio as 1:1. The average of the fresh cell weight obtained under intermittent light was 2.67 g/L, whose NBL was reduced by 62% compared to the NBL under natural condition. In terms of relative electric power and photon yield, the intermittent time with 150 minutes was 72% higher than it was with continuous light condition. As the intermittent light time extended, certain fatty acid methyl ester concentration of C18:1 and C18:3 was increased.
