towards biodiesel production

Domain : Eukaryota

Kingdom : Chromalveolata

Phylum : Heterokontophyta

Class : Eustigmatophyceae

Family : Eustigmataceae

Genus : Nannochloropsis

Species : oculata

(Hibbert, 1981)

Taxonomy :

Nannochloropsis oculata (Hibbert)

• Small spheres with diameter of 2 – 4 µM

• One single Chloroplast without pyrenoid, butcontain several lamella, each with 3thylakoids.

• Has polysaccharide cell walls

• Do not accumulate starch

• Non-motile microalgae (non flagellate)(Boussiba et al., 1987)

Morphology

• Not distinguishable by morphologicalcharacteristics, only by molecular technique.

• Marine environment, but other species are alsofound in fresh water and brackish water

(Fawley and Fawley, 2007)

• Contain pigments; Chl α, β-carotene,xantophylls, violaxanthin and vaucherxantinbut lack chl β. (Cohen 1999)
