Antimicrobial and Genotoxicity Effects of Zero-valent Iron Nanoparticles
BACKGROUND In a world of nanotechnology, the first concern is the potential environmental impact of nanoparticles. An efficient way to estimate nanotoxicity is to monitor the responses of bacteria exposed to these particles. OBJECTIVES The current study explored the antimicrobial properties of nZVI (zero-valent Iron nanoparticles) on the Gram-negative bacterial systems Erwinia amylovora, Xant...
متن کاملantimicrobial and genotoxicity effects of zero-valent iron nanoparticles
results: the lowest concentrations of nzvi that inhibited the visible growth (mic) of e. amylovora, x. oryzae, b. cereus and streptomyces spp. were 625, 550, 1250 and 1280 ppm, respectively. the minimum bactericidal concentration (mbc) for e. amylovora and x. oryzae were 10,000 and 5,000 ppm of nzvi, respectively. mbc was not observed for the gram positive bacteria. no bacteriostatic and bacter...
متن کاملCharacterization of zero-valent iron nanoparticles.
The iron nanoparticle technology has received considerable attention for its potential applications in groundwater treatment and site remediation. Recent studies have demonstrated the efficacy of zero-valent iron nanoparticles for the transformation of halogenated organic contaminants and heavy metals. In this work, we present a systematic characterization of the iron nanoparticles prepared wit...
متن کاملPreparation and Characterization of Zero Valent Iron Nanoparticles
In the present work, nano scaled zero valent irons (nZVI) were synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for weeks. A systematic characterization of nZVI was performed using UV, XR...
متن کاملDegradation of Lindane by Zero-Valent Iron Nanoparticles
Thus far, zero-valent iron has been studied mostly for the degradation of structurally simple oneand two-carbon halogenated organic contaminants such as chlorinated methanes, ethanes, and ethenes. In this research, laboratory synthesized particles of nanoscale iron were explored to degrade lindane, also known as -hexachlorocyclohexane, a formerly widely utilized pesticide and well-documented pe...
