Inhibitory Potential of Nanoparticles on Some Harmful Microalgae Microcystis Species

Abstract

Harmful algal blooms (HABs) consider a global environmental issue. It has gained massive attention in Saudi Arabia, in which two cases have been recorded in the same period. In 2017, Jeddah city witnessed obviously changing Fish Lake’s color to pink with an unpleasant odor. The second case was in Alhasa city, where dead fish has spread on the coast of Alakeer Alhsa. In both sites, the water was contaminated with sewage. These phenomena were associated with the bloom of microalgal Microcystis sp. and laboratory examination of water samples from Fish Lake and alakeer coast have confirmed the presence of two different genera of Microcystis. In the last decade, the green fabrication of different types of engineered nanomaterials has gained attention owing to their unique physicochemical properties providing wide biomedical applications, among these types, metallic nanoparticles which are capable of developing a cost-effective and efficient candidate for treating many environmental problems. The aim of the article is to be understanding the effects of nanoparticles on growth of harmful algae blooms.
