T. chuiiwas chosen since it has significant economic benefit due to its
ability to provide food cultures for use in shellfish hatcheries that produce
shellfish for human consumption and for its nutritional profile,
that is dense in essential fatty acids . In contrast, P. kessleri does not
have a favorable composition for use in hatcheries or as biofuels since
it contains minimal lipids by weight (0–29%) . Rather, P. kessleri
was selected because of its rapid growth rate and ability to grow
under varying conditions, as well as its similarity to Chlorella vulgaris,
a commercially relevant algal strain . While both of these algae
grow successfully on the substrates, the objective of this research was
to compare the impact of aeroponic culturing of these different algal
species on biomass productivity and fatty-acid composition using the
aeroponic substrate production system.
