the growth were isolated from ponds in the middle Taiwan strains, the experiments were carried out in a photobioreactor with continuous illumination and 3% CO2 aeration in the modified BBM medium. As shown in Fig. 2a, the growth of Chlamydomonas sp. TAI-2 was better than Desmodesmus sp. TAI-1 under the investigated conditions. The biomass concentration produced from Chlamydomonas sp. TAI-2 was approximately 1.34 g/L at day 10, more than that produced from Desmodesmus sp. TAI-1, which was approximately 0.93 g/L. Microalgal biomass was harvested from culture medium every two days and subjected to extraction for lipid content measurement. As shown in Fig. 2b, The biomass obtained from Chlamydomonas sp. TAI-2 has the higher lipid content than Desmodesmus sp.
