Improvement on lipid production by Scenedesmus obliquus triggered by low dose exposure to nanoparticles.

ABSTRACT: Carbon nanotubes (CNTs), α-Fe₂O₃ nanoparticles (nano Fe₂O₃) and MgO nanoparticles (nano MgO) were evaluated for the effects on algae growth and lipid production. Nano Fe₂O₃ promoted cell growth in the range of 0-20 mg·L^-1. CNTs, nano Fe₂O₃ and nano MgO inhibited cell growth of Scenedesmus obliquus at 10, 40 and 0.8 mg·L^-1 respectively. Neutral lipid and total lipid content increased with the increasing concentration of all tested nanoparticles. The maximum lipid productivity of cultures exposed to CNTs, nano Fe₂O₃ and nano MgO was observed at 5 mg·L^-1, 5 mg·L^-1 and 40 mg·L^-1, with the improvement by 8.9%, 39.6% and 18.5%. High
