Marine endophytic actinomycetes isolated from seaweeds was used in assisting the synthesis of copper nanoparticles which were characterized by UV-Visible spectroscopy, FTIR, SEM, TEM and assessed for antibacterial activity against five different human pathogenic bacteria. Freshly synthesized copper nanoparticles showed two absorption bands at 370 nm and 690 nm due to their variable size. FTIR analysis confirmed the capping and stabilization, SEM analysis depicted the morphology, EDX analysis confirmed the presence and TEM analysis provided the size and shape of synthesized copper nanoparticles. Antibacterial activity was observed through zones of inhibition. The results suggested that copper nanoparticles synthesized by the assistance of actinomycetes can be utilized to control the human pathogenic bacteria. (C) 2017 Elsevier B.V. All rights reserved.
