Green biosynthesis of silver nanoparticles using novel endophytic Rothia endophytica: Characterization and anticandidal activity

Promising antimicrobial and antibiofilm activities of reduced graphene oxide-metal oxide (RGO-NiO, RGO-AgO, and RGO-ZnO) nanocomposites

“…13,14 Previous studies have reported that RGO has antimicrobial activity, [15][16][17] and GO when conjugated with active ingredients exhibits antimicrobial and antinematodal activities. 18,19 Furthermore, metal and metal oxide nanoparticles, such as silver, [20][21][22] zinc oxide, [23][24][25] and nickel oxide, 26,27 are widely used as antimicrobials, and a silver boron nano-formulation is a potential nematicide. 28 Furthermore, RGO-based metal oxide nanocomposites have garnered much attention as antimicrobials in the last few years.…”

Bacillus megaterium-Mediated Synthesis of Selenium Nanoparticles and Their Antifungal Activity against Rhizoctonia solani in Faba Bean Plants

“…The next step was mixing cell-free supernatant with the selenious acid suspension (1 mM) by quotient (1:1) v/v. The mixtures were stirred at a controlled room temperature of about 25 • C. The process of selenious acid reduction was monitored by color change of the cell-free supernatant from colorless to reddish color [22][23][24][25]. The suspension of SeNPs was further centrifuged at 12,000 rpm for 30 min, and the collected precipitate pellet was dried and weighed.…”

“…Although fungicides are effective for controlling R. solani, they pollute the environment, have a high cost, and also affect other beneficial organisms in the soil [16]. Fungi are the largest group among microbes, where are used in different applications as nanotechnology, bioremediation, bio-deinking, food products, enzyme production, organic acids, and biofuels [17][18][19][20][21][22][23]. Dong et al [24] reported that the management of plant diseases can be achieved by Gly-Cu(OH) 2 NPs by reducing the phytotoxicity to plants and improving the utilization of copper-based bactericides.…”

Ecofriendly preparation of silver nanoparticles-based nanocomposite stabilized by polysaccharides with antibacterial, antifungal and antiviral activities

“…The sequence consensus was compared with NCBI Gene Bank data base using the NCBI BLAST program. Phylogenetic analyses were performed using the neighbour-joining method based on 1000 replicates using MEGA 7.0 software (Elbahnasawy et al 2021b ).…”
