Microalgae is acknowledged as a kind of promising non-food biomass for fuel and chemicals production owing to its high photosynthetic efficiency, by which light, carbon dioxide and other nutrients could be converted to lipids, carbohydrates and *** vast microalgae species, Chlorella, which could be easily and fast cultivated, has been considered as a promising feedstock for large scale cultivation to produce biofuel and value added *** have focused on various issues of Chlorella, including different trophic modes for efficient biomass growth, the application of N-deficiency culture for increasing calorific values and, the regulation of iron concentration for higher lipid *** this work, different light intensities (80, 160, 240 and 320 μmol/m2s) and various mediums including control medium (CM), N/P rich medium (NPM), N rich medium (NM), and P rich medium (PM) were applied for cultivation of Chlorella *** was revealed that cultivation of Chlorella *** CM under the light intensity of 320 μmol/m2s led to a lipid content up to 30% enhancement, which was higher than the results of other cases.A rather high unsaturated fatty acid (UFA) content of 7.5% and unsaturated fatty acid/total fatty acid (UFA/TFA) ratio of 0.73 were obtained under 320 μrol/m2s in CM, indicating that the CM-320 system was applicable for the generation of ***, Chlorella *** in PM under 320 μmol/m2s provided higher TFA content (7.3%), which was appropriate for biofuel production.
