“…Until now, the AgNPs were synthesized by bacteria (13), plants (14), fungi (15), Algae (16), and yeasts (17). Inorganic nanoparticles can be generated using micro-organisms through either extracellular or intracellular activities (18). The extracellular biosynthesis of the nanoparticles is economic compared to the intracellular method, because of the simplicity of the production process.…”

“…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.

“…Bacteria cultured in high concentration of silver nitrate can accumulate silver in large bulk (with nanoscale 200 nm diameter) [24] . Proteus mirabilis PTCC 1710 found even more proficient for NPs synthesis [25] . Further, it was reported that during incubation of bacteria the type of broth (nutrient broth, Muller-Hinton broth) used may promote synthesis of NPs (extracellular or intracellular).…”

Qidwai, et al.: Biogenic Advances in NanoparticlesInnovations in the nanotechnological arena have paved a path leading to nano-revolution, which has most recently unfurled the role of plants in the biogenic synthesis of nanoparticles. Though synthesis of nanoparticles can be accomplished through physical and chemical techniques, biological course of synthesis has proficiently proved competent over other techniques. The problem of evolving multidrug resistant bacteria, due to irrational use of antibiotics, makes the biogenically synthesized nanoparticles attractive, due to their promising efficacy with negligible side effects. Consequently, the nanoparticles becoming better substitutes for conventional treatment besides overcoming all the limitations. Nanoparticles have great stability and potent antibacterial activity. The uniqueness lies in their size (10 and 500 nm) and dimension offers these particles to dynamically communicate with biomolecules on the cell surfaces and within the cells, so proficiently to decode and designate various biochemical and physiochemical properties of the cells. The present review aims to recapitulate various emerging efforts in the biogenic synthesis of nanoparticles, most significantly their unique mechanisms of action with different approaches as well as the factors that may add up to their antimicrobial activity.
