Seaweed Mediated Biosynthesis of Silver Nanoparticles Using Gracilaria fergusonii J.Ag. Collected From Hare Island, Thoothukudi in the South East Coast of Tamil Nadu, India
Abstract: In the present study silver nanoparticles were synthesized using the aqueous extract of red seaweed Gracilaria fergusonii J.Ag. as the reducing agent. The formation of silver nanoparticles was confirmed by colour change from light yellow to dark brownish red, UV– visible spectroscopy, FT-IR, X-ray diffraction method (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray microanalysis spectroscopy (EDS). The anoparticles showed an absorbance at 442 nm on UV–visible spectroscopy. The …

Phytoremediation of Lead by Brassica juncea and Vetiver zizanioidus
Abstract: The engineering-based remediation technologies of heavy metals from contaminated soil are time consuming, expensive, and create noise to the environment. Accumulation of heavy metals such as Pb, Cd, Hg, Cr, and Ni is destructive to not only plants and animals but also to complete ecosystem. Lead contamination keeps on increasing day by day from industrial waste, paints, ceramics, use of biosolids, and many more. Metals cannot easily degrade, so effective …

Bacterial Diversity of Decomposing Leaf Litters of Polyalthia longifolia (Sonner.) Thw. and Rhododendron arboreum Sm. Under Natural Condition
Abstract: The role of microorganisms in the decomposition of plant material is of immense importance. A large amount of plant litter is added annually to the soil through leaf fall and death of plants. As the plant materials fall on the ground, they are immediately attacked by various groups of soil microorganisms and soon after, the process of decomposition is initiated. Microorganisms being heterotrophic in their mode of nutrition are responsible …

Nitric Oxide & Inducible Nitric Oxide Synthase: A Glimpse on Biological Role
Abstract: Nitric oxide (NO) is a multifunctional molecule having numerous physiological and pathophysiological functions. It is synthesized from L-arginine by three different isoforms of nitric oxide synthase (NOS), which are categorized into two subtypes; constitutive nitric oxide synthase (cNOS) and inducible nitric oxide synthase (iNOS). Constitutive nitric oxide synthase (cNOS) is constitutively expressed in the cells, while inducible nitric oxide synthase (iNOS) is expressed within several hours after the stimulation of …

Biosynthesis of Silver Nanoparticles Using Plant Extract
Abstract: In recent years, research in nanotechnology deals with the development of environmental-friendly processes for the synthesis of stable nanoparticles, possessing well-defined shapes, and controlled narrow sizes. Additionally, due to a vast demand for precious metals (like silver) in the fields such as electronics and catalysis, recovery of silver from both primary and secondary sources is of most significance. Biological recovery of precious metals with the formation of their nanoparticles is …
