Hydrolysate derived from the experimental alga was investigated
for bioethanol production through a yeast based fermentation
process using S. cerevisiae. The results showed that the
highest bioethanol yield (0.158 g bioethanol/g residual biomass)
was achieved at 120 h of fermentation (Fig. 5). Nguyen et al. [69]
reported maximum bioethanol yield up to 29 wt% in acid
pre-treated Chlamydomonas reinhardtii biomass. Schultz-Jensen
et al. [70] studied simultaneous saccharification and fermentation
methods on the production of bioethanol from the fresh macroalgal
biomass of Chaetomorpha linum and observed 77% of theoretical
ethanol yield. In the present study after simultaneous saccharification
and fermentation, the lipid extracted residual biomass produced
72.5% of theoretical bioethanol yield.
