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 lmol/m2 s in CM, indicating that
the CM-320 system was applicable for the generation of UFA. Moreover, Chlorella sp. cultivated in PM
under 320 lmol/m2 s provided higher TFA content (7.3%), which was appropriate for biofuel production
depended on the concentration of these two components. At a given glucose concentration, an increase in fatty acid production was obtained
by increasing the sodium thiosulphate concentration. In contrast, an increase in glucose concentration caused a decrease in fatty acid
production when the sodium thiosulphate concentration was fixed. These results suggest that an appropriate concentration of glucose in
combination with sodium thiosulphate can enhance the accumulation of lipids of Chlorella sp. cells.
