Abstract
CURRENTLY, there is a growing need to develop environmentally …. benign nanoparticle synthesis process that does not use toxic chemicals in the synthesis protocols. Synthesis of nanomaterials by biological approach is innovative, cheaper and environmentally friendly. In this regard, the present study focused on the synthesis of silver nanoparticles from the microalga Isochrysis galbana. The silver nanoparticle produced by marine microalga Isochrysis galbana when incubated with silver nitrate solution at the same culture condition for 24 h and was detected by UV-Vis spectrophotometer, Energy dispersive X-ray (EDX-ray) and Transmission electron microscope. The synthesized silver nitrate nanoparticles from the marine microalga Isochrysis galbana showed the pronounced antibacterial activity against the tested human pathogens Escherichia coli and Proteus vulgaris. The above eco-friendly synthesis procedure of silver nitrate nanoparticles could be easily scaled up in future for the industrial and therapeutic needs.
