Our data are consistent with those reported by other studies of
Y. lipolytica cultured with biodiesel-derived glycerol. The present
study evaluated multiple substrates, nitrogen levels, biomass productivities,
and neutral lipid compositions. While others have
independently studied these conditions, we examined all conditions
simultaneously. This allows for a more comprehensive evaluation
of the relationship of carbon and nitrogen sources and
quantities, and their affect on single cell oil production.
