Due to the large size (typically 2–4 mm in diameter), the fungi–
algae pellets formed during culture could be harvested directly by
simple filtration method, making such harvesting process more
environmentally friendly and economically viable compared with
traditional harvesting technologies. The analyses of the fatty acid
profiles of the harvested fungi–algae pellets grown on autotrophic
and heterotrophic growth mode showed that C16–C18 accounted
for 85.26% and 92.36% of total fatty acid, respectively (Fig. 6), and
the lipid contents were 17.23% and 36.21% of total algal biomass,
respectively, which could be converted to high-quality biodiesel
directly through transesterification process [18].
