Description 766-775
Selenium (Se), a
non-metallic chemical element exhibits many properties like relatively high
thermoconductivity, superconductivity, catalytic activities.  In addition, Se is one of the key elements
for maintaining the health of mammalian animals because of its anti-oxidative
and pro-oxidative effects.  In the present study, we describe the biosynthesis of
highly stable selenium nanoparticles using three species of non-pathogenic,
ecofriendly and easily available Lactic acid bacteria (LAB): Lactobacillus acidophilus, Lactobacillus
plantarum and Lactobacillus rhamnosus
was reported. Lactic acid bacteria can reduce selenium ions to
elemental selenium nanoparticles (SeNPs) and deposit them in intracellular
spaces.  Reduction of Se+ ions
in metal nanoparticles was investigated virtually by tracing the solution color
which changed red after 48 hrs.  
Biosynthesized selenium nanoparticles were spherical (by TEM) in shape
with size range of 20nm to 150 nm (UV spectrum). Moreover, as inferred from the
FTIR spectrum, the presences of highly stable carbonyl group from the
aminoacids have the strong ability to bind with the metal.   Nanoparticles were further analysed for
antimicrobial activity against pathogenic fungi, and they exhibited significant
microbial activity.
