- The effect of different light spectrum and CO2 concentrations on the growth and
lipid content of Micractinium pusillum and Ourococcus multisporus was
investigated. The highest biomass yields (2.9 and 2.6 g-dry cell weight l -1) were
observed for M. pusillum and O. multisporus, respectively, at 5% CO2 with red
light illumination. Red light spectrum with 5% CO2 supported the highest lipid
contents (20% and 27%) and lipid productivity (32 and 36 mg l -1 d -1) for M.
pusillum and O. multisporus, respectively. The highest fatty acid methyl esters
content for both microalgal species was observed under red light spectrum and 5%
CO2 conditions, with the oleic acid fraction ranging between 35% and 37%. This
study showed that the red light spectrum and 5% CO2 were the optimum conditions
for maximum growth, lipid content and lipid productivity of both microalgae species, which could be further exploited to establish a microalga-based biodiesel production strategy.
