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

Antibacterial effect of mycological synthesized silver nanoparticles using Aspergillus oryzae and Fusarium solani filtrates
In this study two novel marine fungal isolates (Aspergillus oryzae and Fsarium solani) were used for generating silver nanoparticles (SNPs). The antibacterial effect of mycological synthesized SNPs (12.31±0.26 and 22.6 ±1.2nm for A. oryzae and F. solani, respectively) was tested against Grampositive (Bacillus cereus SBTBC, Enterococcus faecalis 8J, Lesteria monocytogenes 10403S and Staphylococcus aureus 7A) and Gram-negative bacteria (Escherichia coli ...

Biosynthesis of silver nanoparticles using Aspergillus oryzae and its extracellular protein profile
The biological generation of silver nanoparticles (AgNP) is a straight forward process. However, the mechanism by which this process takes place is unclear. We demonstrate the synthesis of AgNPs using fungal filtrate of Aspergillus oryzae. A characteristic peak of AgNP formation was detected at 435 nm. Eight most prominent extracellular protein bands were identified using MALDI/TOF Mass spectrometry. Here, we ... Read more
