“…C.Albicans was less sensitive to Biogenic-AgNPs with a MICs of 66.7 while A.Brasiliensis has a MIC of 14.1 µg/ml, exhibiting reasonably strong antifungal activity (Table 2 ). Such results are in a good agreement with the previously published paper considering silver nanoparticles from Enteromorpha flexuosa and A. brasiliensis showing MICs against C. albicans ranging between 25 and 300 µg/mL, repectively [34] [35].

Biogenic-Silver nanoparticles emerge as new nanosilver platfmorm that allow to obtain silver nanoparticles via “green chemistry”. In our study we obtained biogenic-Silver nanoparticles from Iris tuberosa leaves extract. Nanoparticles were characterized by UV-vis spectroscopy, dinnamical light scattering technique and Transmission electron microscope, showing spheric and irregular nanoparticles with 5 to 50 nm in diameter. Antioxidant and antimicrobial properties were evaluated against typical microbial contaminants found in cosmetic products, showing high antioxidant and antimicrobial properties. We formulated a natural moisturizing cream with biogenic-silver nanoparticles to evaluate the preservative efficiency trought challenge test, confirming that our nanoparticles are a promising alternative to use as cosmetic preservative.

“…The last step, silver nitrate solutions were then added into the obtained fermentation broths, and adjusted to a final concentration of 10 mM in a conical flask wrapped with tinfoil 26 . The color changes of the solutions were observed after 4 d culture at 28 °C in the dark 27 . The optimal synthesis conditions of BioAgNPs were determined, including Ag + concentration, pH and reaction time 28 .…”

AgNPs are nanomaterials with many potential biomedical applications. In this study, the two novel yeast strains HX-YS and LPP-12Y capable of producing biological silver nanoparticles were isolated. Sequencing of ribosomal DNA-ITS fragments, as well as partial D1/D2 regions of 26S rDNA indicated that the strains are related to species from the genus Metschnikowia. The BioAgNPs produced by HX-YS and LPP-12Y at pH 5.0–6.0 and 26 °C ranged in size from 50 to 500 nm. The antibacterial activities of yeast BioAgNPs against five pathogenic bacteria were determined. The highest antibacterial effect was observed on P. aeruginosa, with additional obvious effects on E. coli ATCC8099 and S. aureus ATCC10231. Additionally, the BioAgNPs showed antiproliferative effects on lung cancer cell lines H1975 and A579, with low toxicity in Beas 2B normal lung cells. Therefore, the AgNPs biosynthesized by HX-YS and LPP-12Y may have potential applications in the treatment of bacterial infections and cancer.

AgNPs is nanomaterials with many potential biomedical applications. In this study, two novel yeast strains named as HX-YS and LPP-12Y capable of producing biological silver nanoparticles were isolated. Based on sequencing of ribosomal DNA-ITS fragments, as well as partial D1/D2 regions of 26S rDNA be similar with genus Metschnikowia. The BioAgNPs produced by HX-YS and LPP-12Y at pH of 5.0 - 6.0 and 26℃ ranged in size from 50 to 500 nm. The antibacterial activities of yeast BioAgNPs against five pathogenic bacteria were determined.
