Efficient Culture Method of Pavlova Lutheri by Light Intensity Control

Abstract

Using artificial lighting, productive cost is high, and reducing the cost is an important factor of cultivation. To reduce productive costs, an economical method of culturing micro-alga, Pavlova lutheri using light intensity control was considered. Minimum light supply to grow cell was calculated using the growth curve at 10,30,60 and 100% light intensity. When light intensity control was simulated, consumption energy of light was reduced about 40% of 100% light intensity. In The actual growth using light intensity control, consumption energy was reduced about 60% of 100%light intensity.
