Abstract/OtherAbstract:
Eustigmatos cf. polyphem is a yellow-green unicellular edaphic microalga belonging to the eustigmatophyte. The characteristics of lipids accumulation of E. cf. polyphem grown in a bubble cylindrical photobioreactor under nitrogen-limited conditions was dissected by morphological and spectrometric analyses. Total lipids accumulation rate increased rapidly at early growth phase, with the emergence of many small lipid bodies. Afterwards, lipid bodies became abundant and enlarged primarily because of the progressive accumulation of lipids and the fusion of nearby lipid bodies. Maximum total lipids and neutral lipids content reached up to 60.59 % and 53.08 % of cell dry weight, accompanied with a biomass dry weight 7.9 g/l. E. cf. polyphem is thus referred to as an oleaginous microalga for biodiesel production due to its high biomass and considerable production of oils.
