“…Synthesis of nanoparticles using microbes have great potential and huge benefits to human, because they eliminate the use of toxic chemicals and minimize the production cost involved in the synthesis. One of the main advantages of biosynthesis of metal nanoparticles is their immense role in the protection of environment which is also the ultimate target of other green technologies [36,37]. Recently, mycogenesis of nanoparticles has attracted much attention of researchers; however, the exact mechanism related to the synthesis has not been understood yet.…”

Nanotechnology mainly involves the fabrication, manipulation, and utilization of materials in nano size (materials having size less than a micron to that of individual atoms). However, nanoparticles can be synthesized by several chemical and physical approaches; now, it is also possible to integrate the use of biological entities. In recent years, mycogenesis of nanoparticles is considered as a prominent way where fungi can be used for the production of nanostructures with desirable shape and size intracellularly or extracellularly. Several researchers have reported that NADH-dependent nitrate reductase enzyme plays an important role in transformation of metal ions into metal nanoparticles. The size and shape of the nanoparticles depend on the microorganism utilized and experimental condition employed during synthesis process. Nanoparticles synthesized from microbes are safe, environmental benign and have several applications in agriculture, textile, medicine, drug delivery, biochemical sensors and allied areas. Future challenges may include large-scale production, enhancement of stability, reduced time to obtain desirable shape and size and their possible applications in several fields. In this review paper, we provide a brief overview on the emerging role of fungi in the synthesis of metal nanoparticles, possible mechanisms and their potential bio-prospective applications.

In the scientific literature, there is a clear lack of information about deciphering of possible mechanisms of creating metal nanoparticles. The methods described so far are primarily based on the enzymatic reduction (dehydrogenase) relied on the nicotinamidoadenine-dinucleotide (NADH) oxidation [1]. In simultaneous oxidation-reducing reactions, the proper environment was created because of need for reducing metal cations, most often to the form of non-reactive metallic nanoparticles. Similar applications were also shown by reducing sugars [2] or flawonoids [3][4][5][6], as examples of chemical compounds of natural origin. The idea of formation nanoparticles was based on the use of an environment that had properties of reducing metal cations to inert particles having most often nanometric dimensions.

“…In addition, the presence of bands at that spectral range suggested that the capping capping agent of biosynthesized nanoparticles possesses an aromatic amines group with specific signatures of amide linkages between amino acid residues in the proteins along with infrared region of the electromagnetic spectrum. The proteins are potential biomolecules responsible for the reduction and capping of the AgNPs synthesized [26,27].…”

In the past, several repeated infectious diseases have been reported due to extended-spectrum β-lactamases (ESBL) producing multidrug resistant (MDR) enterobacteriaceae [1]. Generally, ESBL producing Gram-negative bacteria are resistant to penicillin and cephalosporin antibiotics. It has ability to hydrolyze broad spectrum antibiotic containing an oximino group and are inhibited by β-lactamase inhibitors such as clavulanic acid, sulbactam and tazobactam. The E. coli and K. pneumoniae are predominant ESBL producers cause urinary tract infection, diarrhea and life threatening disease like bacteremia in humans. It has been reported that, ESBLs producing MDR Enterobacteriaceae, especially E. coli and K. pneumoniae are resistance to third-generation cephalosporins antibiotics [2,3]. Furthermore, the infectious antibiotic resistance pathogens are playing an important role in the establishment of unknown diseases in human and animals, which are the major problems in the current scenario.
