title: Studies on the effects of zerovalent iron nanoparticles on bacteria from the mangrove ecosystem.
abstract: Zerovalent iron (ZVI) nanoparticles are gaining popularity in bioremediation of contaminated ground water and antimicrobial studies. In this study, ZVI nanoparticles were synthesized by borohydride method. The effect of these nanoparticles to alter the cell surface hydrophobicity of mangrove bacteria was studied by bacterial adhesion to hydrocarbon assay. The effect of these nanoparticles on the growth and extracellular polymeric substances (EPS) of a novel bacterial strain Halobacillus trueperi MXM-16 from mangroves was evaluated by growing the culture in the presence of ZVI nanoparticles and SEM. The change in the emulsifying ability of the cell-free supernatant of Halobacillus trueperi MXM-16 when grown in media amended with ZVI nanoparticles was also investigated by spectrophotometric analysis.
