“…The production of AgNPs using sulfide (Ag 2 S) and oxide (Ag 2 O) of silver has also been reported by various studies. 31,156 In a recent report, the culture supernatant of bacterium Bacillus licheniformis was used to produce 40 and 50 nm AgNPs, respectively. 157,158 AgNPs of 1-6 nm size has also been produced using visible light emission from the supernatants of Klebsiella pneumoniae.…”

Silver nanotechnology has received tremendous attention in recent years, owing to its wide range of applications in various fields and its intrinsic therapeutic properties. In this review, an attempt is made to critically evaluate the chemical, physical, and biological synthesis of silver nanoparticles (AgNPs) as well as their efficacy in the field of theranostics including microbiology and parasitology. Moreover, an outlook is also provided regarding the performance of AgNPs against different biological systems such as bacteria, fungi, viruses, and parasites (leishmanial and malarial parasites) in curing certain fatal human diseases, with a special focus on cancer. The mechanism of action of AgNPs in different biological systems still remains enigmatic. Here, due to limited available literature, we only focused on AgNPs mechanism in biological systems including human (wound healing and apoptosis), bacteria, and viruses which may open new windows for future research to ensure the versatile application of AgNPs in cosmetics, electronics, and medical fields.

“…In contrast to the herbal type, biosynthesis of NPs by bacteria does not have the disadvantages of high polydispersity index (PDI) in NPs production due to the lack of multiple secondary metabolites including polyphenols and flavonoids [31]. In the case of bacterial approach for biosynthesis of NPs, it can utilize culture supernatant [32,33], bacterial biomass [34], cell-free extract [35], and bacterial derived components [36]. Therefore, in this study, we used culture supernatant as the extracellular approach of biosynthesis CuO NPs due to the simple recovery of NPs compared to the intracellular mode [37].…”

In nanotechnology, using of metallic nanoparticles (MNPs) has obtained major attention for over a century because of their unique properties in nano scale. In this paper, the effect of three factors (incubation time, concentrations of copper sulfate and glucose) on the biosynthesis of copper (II) oxide nanoparticles (CuO NPs) by Halomonas elongata IBRC-M 10214 and the antibacterial activity of nanoparticles were evaluated. Experiment design and analysis of Taguchi method were carried out by Qualitek-4 software. Effect of CuSO4 concentration (1.4, 2.8 and 5.6 mM), incubation time (48, 72 and 96 h) as three different levels was measured as three major factors in the biosynthesis of metallic nanoparticles. Synthesized CuO nanoparticles were characterized by utilizing ultraviolet-visible (UVVis) spectroscopy, X-ray diffraction (XRD), Fourier transform infra-red (FT-IR) spectroscopy and field emission scanning electron microscope (FESEM) techniques. Among the three factors, results illustrated that considerable effect was related to CuSO 4 concentration. These analyses demonstrated that the average CuO nanoparticles crystalline size was 57-79 nm with rectangular shape. Also, for evaluating of antibacterial effects, maximum zone of inhibition, two important multidrug resistant pathogenesis bacteria, Escherichia coli ATCC 25922, and Staphylococcus aureus ATCC 43300 were used. Antibacterial assay of CuO nanoparticles showed antibacterial activity toward the pathogenic bacterial strains of E. coli by 5 mm and S. aureus by 5.5 mm for maximum zone of inhibition. In conclusion, this study presented simple, low expensive, eco-friendly and high productivity in the fabrication of CuO nanoparticles. In addition, these metallic nanoparticles had antibacterial effect that could be usable in medicinal aspect for fighting against prominent pathogen bacteria such as E. coli ATCC 25922 and S. aureus ATCC 43300.

“…Biomolecules present in bacterial extracts can be used to reduce metal ions to nanoparticles in a single-step green synthesis process (Hebbalalu et al, 2013). Extracts of a diverse range of bacterial species have been successfully used in making nanoparticles (Samadi et al, 2009;Ramanathan et al, 2010;Debabov et al, 2013;Malarkodi et al, 2013;Paulkumar et al, 2013). The RPT-0001 synthesized silver nanoparticles were inhibitory against all food-borne bacterial pathogens tested implicating their potential in various antibacterial applications involving foodborne pathogens.…”

Infirmity and death from diseases caused by unsafe food are a continual hazard to communal health safety and socio-economic growth throughout the world. Chemical preservatives are associated with health hazards and toxicity issues. In the study reported here, 200 soil isolates from Western Himalayan region in India were screened for potential antibacterial activity against food-borne pathogens. This study led to the isolation of a bacterial strain belonging to the Genus Bacillus and was designated as RPT-0001. The associated antibacterial activity was sensitive to pronase E treatment. Bioassay-guided fractionation using reverse phase high performance liquid chromatography (RP-HPLC) led to isolation of the antibacterial peptide designated as RPT-0001. The molecular weight of RPT-0001 was determined by electro-spray ionization mass spectroscopy (ESI-MS) as 276.9 Da. RPT-0001 was inhibitory to both Gram-negative and Grampositive food-borne bacteria tested. The characteristics of RPT-0001 do not match with that of any other known antibacterial peptides produced by Bacillus sp. or related genera. Purified RPT-0001 was successfully used in synthesis of silver nanoparticles effective against food-borne pathogenic bacteria. The antibacterial peptide and silver nanoparticles synthesized utilizing it as a capping and reducing agent hold promising potential in food preservation, in packaging material and as a therapeutic agent in the treatment of foodborne infections.
