Abstract:
The present study demonstrates the enhancement of microalgae growth using newly designed reflector coated algal culture box having LED as a light source with various light qualities. The highest biomass (5.2 g L−1) was observed under red illumination with reflector. Whereas total chlorophyll (30.4 ± 2.2 g L−1), lipid (53.3%), lipid productivity (27.7 mg L−1 day−1) and total fatty acid (79.4%) were observed under blue LED with reflector. LED illumination with a reflector coat on culture box provide high efficiency and deep-equal light penetration that improved the specific growth rate (white, 0.252; blue, 0.352; green, 0.117 and red, 0.44 day−1) and reduced cultivation time compared to normal culture condition. This modified algal culture box setup can be utilized to reduce the self-shading mechanism in the algae culture; it can reduce the culture period and minimize the cost of production.
