Abstract
Biofuel generation from algae can be increased by using nanotechnology. The present
study emphasizes the use of silver nanoparticles on algae for algal fuel generation along with the
impact of nanoparticles on biomass, metabolites and lipid profile. Silver ion amassing was enhanced
in each algal species, but maximum phytoremediation was found in Ulothrix sp. Carbohydrates
increased 3.2 times in Oedogonium sp., 3.3 times in Ulothrix sp., 3 times in Cladophora sp. and 2.7 times
in Spirogyra sp. Additionally, the application of nanoparticles enhanced by 2 times the production
of proteins in Oedogonium sp., 1.9 times in Ulothrix sp., 1.9 times in Cladophora sp. and 2.1 times
in Spirogyra sp. Finally, the total lipid yield increased 60% DCW in Oedogonium sp., 56% DCW
in Ulothrix sp., 58% DCW in Cladophora sp. and 63% DCW in Spirogyra sp. using 0.08 mg/L silver
nanoparticle application. The lipids and fatty acid fractions from algae containing high concentrations
of C16:0, C18:0 and C18:1 enhanced with silver nanoparticle addition were comparable with EN 14214
and ASTM 6751 biodiesel standards. This study indicates that the uptake of AgNPs can enhance the
production of fatty acids and be commercialized as sustainable biodiesel. The algae Ulothrix sp. is
evidenced as the best competent feedstock for biofuel production.
