Yields are given as the percentage (w/w) of total fatty acids (FA) with standard deviation (± SD) of triplicate measurements. Common names are given where available
C:D, lipid number, expressed as the number of carbon atoms to double bonds. Double bond locations are numbered in parentheses. CN_i, cetane index, measures the combustibility and ignitability of individual FAMEs. CN, cetane number, measures the combustibility and ignitability of biodiesel mixture
