Biodiesel contents in Biofuel(oil) of N. oceanica:
The results also showed that the highest percentages of biodiesel were
obtained by RL, PM and C, respectively, while the lowest percentage was
shown by the control group and A, as shown in Figure (5).

Fatty acid profiles in the produced biodiesel in the different organic me-
dia
In Table (3), concerning the biodiesel analysis, the highest total saturated
fatty acids (TSFA) percentage was obtained by RL, PM,A and B, respectively
as compared with control. This increase in saturated fatty acid (SFA) was due
to increasing palmitic acid (C16:0) in the same last order against control.
On the other hand, the highest unsaturated fatty acid contents (UFA)
were achieved by control, RL, CO, B in descending order. However, the high-
est polyunsaturated fatty acids (PUFA) especially ω3 FAs were obtained by
B as compared with other treatments and control .
