The burning of an enormous amount of fossil fuel
has increased the CO2 level in the atmosphere, causing
global warming. Biomass has been focused on as an
alternative energy source, since it is a renewable
resource and it fixes COz in the atmosphere through
photosynthesis. If biomass is grown in a sustained way,
its combustion has no impact on the CO2 balance in the
atmosphere, because the CO2 emitted by the burning of
biomass is offset by the CO2 fixed by
photosynthesis[8,9]. Among biomass, algae (macro and
microalgae) usually have a higher photosynthetic
efficiency than other biomass[10].
