Abstract
Autotrophic microalgal cultures are grown in bioreactors for biomass.
Microalgae have wide range of applications from food and feed to valuable products for ecological applications.
Many factors influence the growth of cell cultures such as light, carbon dioxide and nutrients.
In the present study a lighting system for the bioreactors was designed, and tested the effect of Lumilux lamps with three different colors and their combination on the growth of a marine alga (Nannochlropsis oceancia) and a fresh water alga (Pseudokirchneriella subcapitata). The combination of Cool white and Interna lights gave the maximum growth in both the algae tested.
