Biogenic synthesis, characterization and antibacterial activity of gold nanoparticles synthesised from vegetable waste

Artemisia absinthium Bitki Ekstraktından Altın Nanopartiküllerin Çevre Dostu Hızlı Sentezi ve Antimikrobiyal Aktivitelerin Uygulanması

“…Measurements were taken at different time intervals, namely, 0, 5, 10, 20, 30, 40, 50, 60, 90,120 and 180 minutes, using a UV-vis spectroscopy and the color was found to change from light yellow to dark pink-red with the formation of vibrations on the SPR (Dubey et al, 2010) due to reduction (Figure 3). In a study, in which the synthesis of AuNPs was performed using the extract of the Salvia officinalis plant, it was determined that the color change from yellow to dark pink was linked to the formation of the AuNPs (Mythili et al, 2018). A similar conclusion was also made in a study in which the biological synthesis of AuNPs was carried out with the leaf extract of Ziziphus zizyphus (Aravinthan et al, 2016).…”

“…The interest in plant-based synthesis methods increases by day because they are easy to operate and eco-friendly. Vegetable sources such as seeds, leaves, and fruit can be used as a source in AuNPs synthesis (Mythili et al, 2018). The phytochemicals in plant extracts produce AuNPs by reducing the gold metal salt in aqueous solutions (Aravinthan et al, 2016;Teimuri-mofrad et al, 2017).…”

Determination of Antimicrobial and Toxic Metal Removal Activities of Plant‐Based Synthesized (Capsicum annuumL. Leaves), Ecofriendly, Gold Nanomaterials

“…concentrations of 25–100 mg mL −1 were said to be effective. [ 28 ] In another study with Anacardium occidentale , it was reported that 20–40 mg mL −1 concentrations were effective on E. coli and B. subtilis . [ 26 ]…”

Prevalence of antibiotic resistant mastitis pathogens in dairy cows in Egypt and potential biological control agents produced from plant endophytic actinobacteria

“…The disc diffusion method with slight modifications (Mythili et al, 2018), was used to evaluate the antimicrobial activities of the metabolites. Isolated bacteria were inoculated on Muller Hinton agar plates (Himedia, India) (10 7 CFU mL −1 , 0.5 McFarland standard).…”
