Mycogenesis of Silver Nanoparticles and their Antibacterial Effect
Mycological synthesized silver nanoparticles (SNPs) is a promising field of study and addressing the optimized conditions for this production is discussed in detail in this study. Here, we screened 80 novel fungal isolates, obtained from _Padina_ sp. (Algicolous fungi) and _Avicennia__marina_ (Forssk.) Vierh. (Foliicolous fungi) samples, for SNPs generation using fungal supernatants to identify new isolates with enhanced activity. A ... Read more

Synthesis of silver nanooparticles using fusarium solani filtrate

Synthesis of silver nanooparticles using fusarium solani filtrate
There is a growing interest in biosynthesis of nanoparticles using methods that are simple, inexpensive, and non-toxic to the environment. Among the different available methods of synthesis (including physical and chemical methods), the biological methods are considered to be the most convenient in terms of cost and non-hazardous impacts to the environment. Nanoparticles are proven to possess unique chemical and ... Read more

Extracellular generation of silver nanoparticles using Fusarium solani MH005062

Extracellular generation of silver nanoparticles using Fusarium solani MH005062
The mechanism of biological generation of silver nanoparticles (SNP) is still not fully understood with most studies merely providing detailed information describing the mechanism by which fungi reduce AgNO3 into SNP. In our work, we demonstrate that proteins are mainly involved in the myco-generation of SNP. Fifty-three and 27 fungal isolates were obtained from Padina (brown algae) and Avicennia marina ...
