摘要
The patent "Biosynthesis of metal nanoparticles by microalgae (s) and cyanobacterium (s) simultaneously with the cultivation of the microorganism" aims at the development of metal nanoparticles in an environmentally correct manner by microalgae (s) and cyanobacteria (s). being the microalgal and cyanobacterial growth performed simultaneously to the reduction of the metal nanoparticles. Microalgal and cyanobacterial biosynthesis promote reduction in the amount and / or toxicity of industrial effluents containing heavy metals. Thus, the biosynthesis of metallic nanoparticles simultaneously to the microalgae (s) and cyanobacteria (s) cultivation, becomes an alternative to reduce production costs of these nanoparticles. Therefore, the biosynthesis of metallic nanoparticles is a bottom-up process that mainly involves reduction / oxidation reactions, promoting the reduction of the metal using low or zero toxicity reducing agents. eliminating or minimizing costs with the disposal of these wastes, and may be an alternative solution that causes lower risks and environmental impacts. Metal nanoparticles are compounds that are widely used in commercial products such as textiles, paints, conditioning, food packaging and medicine. Microalgal and cyanobacterial biosynthesis of metallic nanoparticles still confers advantage over the traditional chemical method. therefore, microalgae and cyanobacteria produce functional biomolecules that reduce metal ions and adhere to the surface of these nanoparticles. giving the metal nanoparticles different characteristics such as protection and stability, as well as high yield and low production cost.
