“…Alternatively, the plantbased green synthesis of NPs has proven a rapid, ecofriendly process with advances over microbe-mediated synthesis in the time taken for culturing and its maintenance. Due to the diverse characteristics of metallic nanoparticles like size, magnetization property, flexibility, and rigidity, metallic nanoparticles are extensively used in various sectors, including drug delivery, biosensors, catalysis, and antibacterial agents [2,3].…”

This study employed green chemistry to synthesize copper nanoparticles (CuNPs) using fresh root extract of Withania somnifera. The size, shape, morphology, and stability of resultant CuNPs were investigated by UV-Vis spectroscopy, FTIR, transmission electron microscopy (TEM), and energy-dispersive spectrophotometer. Crude extracts were assessed phytochemically to determine the presence of alkaloids, flavonoids, phenols, saponins, steroids, and tannins. The UV-Vis absorption spectra show maximum absorption at 330 nm, and FTIR showed the presence of biological molecules responsible for reducing Cu+ ions. In TEM and EDS analyses, the average diameter of the synthesized NPs was found to be 6.28 ± 1.13 nm . The crystal structure of synthesized nanoparticle was determined using XRD analysis and showed its peak at 36.34°, 43.33°, 50.47°, and 73.57°, which corresponds to the cubic lattice of copper. The synthesized nanoparticles (NPs) were tested for their in vitro antimicrobial activity against bacterial strains E. coli and S. aureus by the agar well diffusion method which showed higher efficiency against S. aureus. The antioxidant activity of the synthesized NPs was evaluated by DPPH assay, and the percentage of inhibition was found to be 62% at the concentration of 400 μg/ml and the IC50 value was 51.53 μg/ml. The present investigation suggests that the biosynthesized CuNPs showed prominent antibacterial and free radical scavenging potential. The result proved that root extract of W. somnifera could be applied for synthesis of nanoparticle CuNPs with high uniform particle size along with potent biological activity.

“…The antibacterial activity of newly synthesized AgNPs may be attributed to the formation of oxidative stress, deterioration in replication of DNA, and also AgNPs can directly reason lysis of bacterial cell via damaging the cell membranes. 29 As mentioned above, newly synthesized AgNPs had also DNA cleavage activity. This results from present study can be caused the antimicrobial activity against studied microorganisms.…”

Aim: Mushrooms known that to be used in traditional treatment among the people as they can generate a large diversity of secondary metabolites. In the present study, it was aimed to synthesized silver nanoparticles (AgNPs) mediated Macrolepiota procera, which is known to have diverse biological activities such as anticancer, antioxidant, antimicrobial in previous studies, and to investigated various in-vitro biological activities of these AgNPs. Materials and Methods: Synthesized Mp-AgNPs were characterized using transmission electron microscopy (TEM). Various biological activities including antimicrobial, biofilm inhibition and cell viability inhibition, DNA cleavage, DPPH activity of synthesized AgNPs were investigated in-vitro. Results: The highest DPPH scavenging activity of Mp-AgNPs was found as 92.72%, at 200 mg/L concentration. Mp-AgNPs caused single strain break in the E. coli pBR322 plasmid DNA. Mp-AgNPs showed moderate antimicrobial activity against tested microorganisms. Furthermore, the biofilm inhibition activity of Mp-AgNPs toward P. aeruginosa and S. aureus was 65.80% and 72.60% at 200 mg/L, respectively. Inhibition activity of E. coli cell viability of Mp-AgNPs was found as 99.99% at 500 mg/L. Conclusion: From the findings obtained in the study , the use of M. procera in the AgNPs synthesis it is important private regard due to its low cost, eco-friendly, high yield and non-toxicity human health. In addition, newly synthesized AgNPs can be used effectively for different applications after further studies.

“…Coriander plants have a of lot medical and gastronomy uses. It is s a common spice and a major curry powder ingredient and contains antimicrobial, hypolipidemic, hypoglycemic action and insecticidal properties [ 41 ] due to the presence of phenolic compounds (lignins and flavonoids) mainly located in the leaves [ 41 ]. Therefore, number of leafs and foliar nitrogen are the most important properties.…”

High Resistance of a Sludge Enriched with Nitrogen-Fixing Bacteria to Ammonium Salts and Its Potential as a Biofertilizer

The increasing use of chemical fertilizers causes the loss of natural biological nitrogen fixation in soils, water eutrophication and emits more than 300 Mton CO2 per year. It also limits the success of external bacterial inoculation in the soil. Nitrogen fixing bacteria can be inhibited by the presence of ammonia as its presence can inhibit biological nitrogen fixation. Two aerobic sludges from wastewater treatment plants (WWTP) were exposed to high ammonium salts concentrations (>450 mg L−1 and >2 dS m−1). Microbial analysis after treatment through 16S pyrosequencing showed the presence of Fluviicola sp. (17.70%), a genus of the Clostridiaceae family (11.17%), and Azospirillum sp. (10.42%), which were present at the beginning with lower abundance. Denaturing gradient gel electrophoresis (DGGE) analysis based on nifH genes did not show changes in the nitrogen-fixing population. Nitrogen-Fixing Bacteria (NFB) were identified and associated with other microorganisms involved in the nitrogen cycle, presumably for survival at extreme conditions. The potential use of aerobic sludges enriched with NFB is proposed as an alternative to chemical fertilizer as this bacteria could supplement nitrogen to the plant showing competitive results with chemical fertilization.
