Abstract:

The zinc oxide nanoparticles (ZnO) have more compensations to the magnificent physical and chemical properties. In this study, we evaluate to green synthesis of ZnO nanoparticles from the source of mesophilic bacteria (E. coli) and characterized by several techniques such as UV spectroscopy, DLS, zeta potential, FTIR, XRD and SEM for conforming ZnONPs. Here we first we observed UV-vis spectra analysis that exhibits the spectra characteristic absorption peak of Zn nanocomposite material at 406 nm. The particle size of ZnO was found to be 126.7 nm that was confirmed by DLS. FTIR results revealed that synthesized ZnONPs from mesophilic bacteria having several active functional groups were present. Moreover, crystal-based molecules found in the ZnONPs and it was confirmed by XRD. In our SEM results conformed the ZnONPs exhibits as crystal and irregular shape. Furthermore, the synthesized ZnONPs from mesophilic bacteria (E. coli) scavenges hydroxyl, superoxide, DPPH and ABTs radicals. In addition, ZnONPs from mesophilic bacteria shows potent antimicrobial activity by observing to inhibits the growth of Aspergillus niger, Aspergillus flavus, Fusarium and Rhizopus. This study concluded that efficient method to stably synthesis the ZnONPs by mesophilic bacteria (E. coli) that have potential antioxidants and antimicrobial activity.
