Abstract(s)
Microalgae are a diverse group of organisms
that form the basic component of many eco-
systems. The systemic classification of algae
is primarily based on their pigment composition and is divided into nine classes. The largest
groups are Chlorophyceae (green algae), Phaeophyceae (brown algae),
Pyrrophyceae (dinoflagellates), Chrysophyceae (golden brown
algae), Bacillariophyceae (diatoms) and Rhodo phyceae
(red algae). It has been estimated that between 22,000 and 26,000 species exist
(Norton et al., 1996), of which only a few species have been identified to be useful for commercial application, such as Spirulina, Chlorella, Haematococcus, Dunaliella, Botryococcus, Phaeodactylum and
Porphyridium. Several other species that are also cultivated commercially for the hatcheries in the aquaculture
field include Chaetoceros, Crypthecodinium, Isochrysis, Nannochloris, Nitzschia, Schizochytrium, Tetraselmis
and Skeletonema (Raja et al., 2008).
