Biogenesis of Silver Nanoparticles by Marine Bacteria Labrenzia sp. Mab 26 Associated with Isochrysis Galbana

Abstract

The metabolic or chemical nature of algal–bacterial interactions has opened up unexpected new ways for finding novel microbes with potential for several biotechnological applications. Silver nanoparticles (AgNps) possess many unique and attractive proper-ties which are beneficial to various industries. In this context, the present study was undertaken to explore the bacterial strain Labrenzia sp. Mab 26, isolated from marine microalgae, Isochrysis galbana for AgNp biosynthesis. The synthesized AgNps were further characterized by UV–Vis spectroscopy, XRD analysis, FT–IR spectroscopic analysis and electron microsco-py. This shows that microalgae-associated bacteria can be explored for efficient synthesis of AgNps.
