ANALYSIS OF SOME CHEMICAL ELEMENTS IN MARINE MICROALGAE FOR BIODIESEL
PRODUCTIONAND OTHER USES

Due to the current abundant supply of marine microalgae, which can be found in seawater, as well as microalgae's ability to
uptake different chemicals, it appears as a promising raw material with potential for many commercial uses. Despite having a
high amount of metal in their biomass, the lipids within marine microalgae can be converted into biodiesel. Analyses of 26 chemical
elements (Al, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sn, Sr, Ti, Tl, V, and Zn) were performed by ICP-
OES with the goal of quantifying the inorganic content of marine microalgae's biomass. Regardless of the cultivation media used,
microalgae presented differences in their chemical element profile. Strains showed a 12.9% to 36.3%mass of analyzed elements per dry
biomass, which represent a relatively high percentage for a feedstock used in biofuels. Among the 36 assayed microalgae, Biddulphia
sp., Planktolyngbya limnetica, Amphora sp. (1), Navicula sp. (3) and Synechococcus sp. are most indicated for this purpose as they
contain a lower concentration of chemical elements when compared to other samples. However, their profile warns that water quality
control is needed for toxic metals such as Ba, Cd, and Pb.
