“…The results indicated that seven cyanobacterial strains were capable of producing AgNPs under light, however, only three were capable of producing AgNPs in the dark [42]. The ammonia-sensing potential of the cyanobacterial synthesized silver nanoparticles was also reported [43]. Highly monodispersed AgNPs (5–6.5 nm) were reported through the marine cyanobacterium Phormidium fragile [44].…”

During the last decade, metal nanoparticles (MtNPs) have gained immense popularity due to their characteristic physicochemical properties, as well as containing antimicrobial, anti-cancer, catalyzing, optical, electronic and magnetic properties. Primarily, these MtNPs have been synthesized through different physical and chemical methods. However, these conventional methods have various drawbacks, such as high energy consumption, high cost and the involvement of toxic chemical substances. Microbial flora has provided an alternative platform for the biological synthesis of MtNPs in an eco-friendly and cost effective way. In this article we have focused on various microorganisms used for the synthesis of different MtNPs. We also have elaborated on the intracellular and extracellular mechanisms of MtNP synthesis in microorganisms, and have highlighted their advantages along with their challenges. Moreover, due to several advantages over chemically synthesized nanoparticles, the microbial MtNPs, with their exclusive and dynamic characteristics, can be used in different sectors like the agriculture, medicine, cosmetics and biotechnology industries in the near future.

“…The rapidly emerging tendency of drug resistant and infectious microbes through fast evolution by mutation has created thrust need to develop advance formulation for the modification or inactivation of such microbes (Mandal et al, 2014). In recent few years several attempts of green synthesis of nanoparticles using the microorganisms such as bacteria, fungi and algae as well as various higher plants part have been made (Maurya et al, 2016;Sanjivkumar et al, 2019;Tomer et al, 2019). The biogenic extract have diversity of phytochemical compounds (alkaloids, amino acids flavonoids, inositol, phenolic compounds, resins, saponins, tannins, terpenes, and vitamins), particularly, secondary metabolites available in plant and animal tissues with unique potential of NPs synthesis (Abbasi et al, 2018).…”

The present study was aimed to synthesize silver nanoparticles (AgNPs)using the extract of oyster mushroom Pleurotuscitrinopileatus and its use in antibacterial testing. This green synthesis approach of silver NPs is very fast, simple, environmentally friendly and economical. The initial confirmation of silver NPs synthesis was observed with the alteration of the colour of the solution from colourless to wine red. The prepared nano-material was further characterized by UV-Visible spectrophotometer, and transmission electron microscopy (TEM). The TEM revealed particle size of synthesized AgNPsbetween the range of 11-13 nm. The bactericidal efficacy of silver NPstested against Escherichia coli confirmed the lowest 50 µg/L concentration of silver NPs bactericidal. Therefore based the observations of the study silver NPsat the level of its 50 µg/L can be used for the purposes of potential water disinfection, killing of bacteria, disinfection of medical equipments, wound washings, preservation of food stuffs and in hand sanitization.

“…Similarly, the direct involvement of noxious chemicals during chemical synthesis of nanomaterials is damaging to the environment and living creatures, which can never be part of the eco-friendly policy. Therefore, keeping view of the above-mentioned concerns, the research has been oriented towards the wide consideration of biogenic or biological approaches using microorganisms including algae, bacteria, fungi, yeast, etc., different parts of higher plants and animals for the green synthesis of NPs (Bhardwaj et al 2018;Katas et al 2019;Sanjivkumar et al 2019;Tomer et al 2019). These synthesis approaches are nontoxic, economical, biocompatible, environmentally benign and uncomplicated establishing green synthesis (Naraian and Bhardwaj 2020).…”

Green synthesis of nanoparticles (NPs) has gained great concern among researchers due to their unique properties, excellent applications and efficient route of synthesis. From the last decades, the number biologicals such as plants, fungus, bacteria, yeast, algae, and cyanobacteria and their products are using by various researchers for the synthesis of different NPs. However, the pillar of green chemistry keeps touching new heights to improve the performance. This review paper unveils almost recent cyanobacteria-assisted greener NP synthesis technique, characterization and application. The enormous potency of cyanobacteria in NP synthesis (silver, gold, copper, zinc, palladium, titanium, cadmium sulfide, and selenium) and significance of reducing enzymes were summarized. The extracellular and intracellular entity such as metabolites, enzyme, protein, pigments in cyanobacteria play a significant role in the conversion of metal ions to metal NPs with unique properties discussed briefly. The green synthesis of nanomaterials is valuable because of their cost-effective, nontoxic and eco-friendly prospects as well as the potential application metal NPs such as antibacterial, antifungal, anticancerous, catalytic, drug delivery, bioimaging, nanopesticide, nanofertilizer, sensing properties, etc. Therefore, in the present review, we have systematically discussed the mechanisms of synthesis and applications of cyanobacteria-assisted green synthesis of NPs.
