“…For example, Liu et al were able to produce Au nanoparticles from dried cells of Bacillus megaterium [166]. A similar study by Sneha et al using a Corynebacterium sp also revealed that a non-enzymatic reduction mechanism was involved in nanoparticle formation [167]. The reduction of nanoparticles is believed to be the result of a combination of several factors.…”

Nanotechnology is the creation, manipulation and use of materials at the nanometre size scale (1 to 100 nm). At this size scale there are significant differences in many material properties that are normally not seen in the same materials at larger scales. Although nanoscale materials can be produced using a variety of traditional physical and chemical processes, it is now possible to biologically synthesize materials via environment-friendly green chemistry based techniques. In recent years, the convergence between nanotechnology and biology has created the new field of nanobiotechnology that incorporates the use of biological entities such as actinomycetes algae, bacteria, fungi, viruses, yeasts, and plants in a number of biochemical and biophysical processes. The biological synthesis via nanobiotechnology processes have a significant potential to boost nanoparticles production without the use of harsh, toxic, and expensive chemicals commonly used in conventional physical and chemical processes. The aim of this review is to provide an overview of recent trends in synthesizing nanoparticles via biological entities and their potential applications.

“…Some of these microorganisms can survive and grow even at high metal ion concentrations [4]. They are often exposed to extreme environmental conditions, which forces them to develop specific defense mechanisms to quell such stresses, including the toxicity of foreign metal ions or metalloids [13].…”

BackgroundThe use of microorganisms in the synthesis of nanoparticles emerges as an eco-friendly and exciting approach, for production of nanoparticles due to its low energy requirement, environmental compatibility, reduced costs of manufacture, scalability, and nanoparticle stabilization compared with the chemical synthesis.ResultsThe production of gold nanoparticles by the thermophilic bacterium Geobacillus sp. strain ID17 is reported in this study. Cells exposed to Au3+ turned from colourless into an intense purple colour. This change of colour indicates the accumulation of intracellular gold nanoparticles. Elemental analysis of particles composition was verified using TEM and EDX analysis. The intracellular localization and particles size were verified by TEM showing two different types of particles of predominant quasi-hexagonal shape with size ranging from 5–50 nm. The mayority of them were between 10‒20 nm in size. FT-IR was utilized to characterize the chemical surface of gold nanoparticles. This assay supports the idea of a protein type of compound on the surface of biosynthesized gold nanoparticles. Reductase activity involved in the synthesis of gold nanoparticles has been previously reported to be present in others microorganisms. This reduction using NADH as substrate was tested in ID17. Crude extracts of the microorganism could catalyze the NADH-dependent Au3+ reduction.ConclusionsOur results strongly suggest that the biosynthesis of gold nanoparticles by ID17 is mediated by enzymes and NADH as a cofactor for this biological transformation.

“…This indicates that reduction processes are not involved in the sorption of Cu 2+ , unlike Ag + . Precipitation of silver metal from silver nitrate solution was previously identified on active biomass [12], lignite [15], activated carbon fibre [16] and activated carbon [17].

“…Different adsorbents were tested for the removal of Cu 2+ from aqueous solutions including lignocellulosic materials (wheat and soybean straws, corn stalks and corn cobs) [8], chitosan resin [9], activated carbons [10] and perlite [11]. Ag + was also removed from aqueous solutions on Corynebacterium glutamicum [12], amino methylene phosphonic acid resin [13], perlite [11], coal [14], lignite [15], activated carbon fibres [16] and activated carbon [17].…”
