Abstract

The drinking water quality must meet both the WHO guidelines and Egyptian standards. This ensures public health and the suitability of water for different uses. The purification of water by biosynthesized silver nanoparticles (AgNPs) Syzygium aromaticum (Clove) is an eco-friendly approach where the clove extract acts as a reducing and stabilizing agent to create AgNPs through a “green synthesis” method. The AgNPs, when combined with the extract, show antimicrobial activities and kill the pathogenic bacteria in water. The water pollution include Staphylococcus, Pseudomonas, Salmonella, Acinetobacter, Flavobacterium, Clostridium, Vibrio and E. coli. In vitro experiments showed inhibition of Staphylococcus spp. in water by clove. Clove oil phytochemical constituents were identified by means of gas chromatography-mass spectrometry (GC-MS) analysis. Ethanolic and aqueous extracts of Clove (Syzygium aromaticum) and thyme (Thymus vulgaris) showed antibacterial activity against specific water pathogens and spoilage microorganisms. The diffusion method was used to determine the antimicrobial activities. The minimum inhibitory concentrations (MIC) of different plant extracts against Gram negative bacteria (Salmonella spp., E. coli, Vibrio spp., and Pseudomonas spp.) and Gram positive bacteria (Bacillus spp. and Staphylococcus spp.) was determined. The biosynthesis of silver nanoparticles has garnered substantial attention in nano biotechnology because to its unique biophysical features, enhanced biocompatibility, and important biological properties in the sectors of biomedicine, industry, agriculture, food processing, and the environment. The medicinal significance of plant extracts because of the presence of a variety of bioactive compounds, such as flavonoids, phenolic acids, terpenoids and alkaloids, which help reduce silver ions (Ag+) for the synthesis of biomolecule, encapsulated Ag NPs.
