    Abstract The rise of antimicrobial resistance has brought into focus the urgent need for the next generation of antimicrobial coating. Specifically, the coating of suitable antimicrobial nanomaterials on contact surfaces seems to be an effective method for the disinfection/contact killing of microorganisms. In this study, the antimicrobial coatings of graphene@curcumin-copper (GN@CR-Cu) were prepared using a chemical synthesis methodology. Thus, the prepared GN@CR-Cu slurry was successfully coated on different contact surfaces, and subsequently, the GO in the composite was reduced to graphene (GN) by low-temperature heating/sunlight exposure. Scanning electron microscopy was used to characterize the coated GN@CR-Cu for the coating properties, X-ray photon scattering were used for structural characterization and material confirmation. From the morphological analysis, it was seen that CR and Cu were uniformly distributed throughout the GN network. The nanocomposite coating showed antimicrobial properties by contact-killing mechanisms, which was confirmed by zone inhibition and scanning electron microscopy. The materials showed maximum antibacterial activity against

The nanocomposite coating showed antimicrobial properties by contact-killing mechanisms, which was confirmed by zone inhibition and scanning electron microscopy. The materials showed maximum antibacterial activity against E. coli (24 ± 0.50 mm) followed by P. aeruginosa (18 ± 0.25 mm) at 25 µg/mL spot inoculation on the solid media plate, and a similar trend was observed in the minimum inhibition concentration (80 µg/mL) and bactericidal concentration (160 µg/mL) in liquid media. The synthesized materials showed excellent activity against E. coli and P. aeruginosa . These materials, when coated on different contact surfaces such medical devices, might significantly reduce the risk of nosocomial infection.

    Abstract In this research, Bougainvillea glabra paper flower extract was used to quickly synthesize biogenic silver nanoparticles (BAgNPs) utilizing green chemistry. Using the flower extract as a biological reducing agent, silver nanoparticles were generated by the conversion of Ag + cations to Ag 0 ions. Data patterns obtained from physical techniques for characterizing BAgNPs, employing UV-visible, scattering electron microscope (SEM), transmission electron microscope (TEM), dynamic light scattering (DLS), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR), suggested that the nanoparticles have a spherical to oval form with size ranging from 10 to 50 nm. Spectroscopy and microscopic analysis were used to learn more about the antibacterial properties of the biologically produced BAgNPs from Bougainvillea glabra . Further, the potential mechanism of action of nanoparticles was investigated by studying their interactions in vitro with several bacterial strains and mammalian cancer cell systems. Finally, we can conclude that BAgNPs can be functionalized to dramatically inhibit bacterial growth and the growth of cancer cells in culture conditions, suggesting that biologically produced nanomaterials will provide new opportunities for a wide range of biomedical applications in the near future.

    Abstract The importance of crucial nutrient factors like Phosphate (P) and their limited availability leads to variable fluctuations in fatty acid and phospholipid synthesis in the green alga. These fatty acids and phospholipids are an imperative byproduct of alga which used in biofuel production. The production of phospholipids in alga might be naturally enhanced by the optimized supplied by specific essential nutrient like Phosphate. In this study, green alga Chlamydomonas reinhardtii was cultivated in phosphate stress condition to obtain maximum phospholipids. In the stress condition, the organism exhibited variable changes in chlorophyll, fatty acid, and phospholipid compositions. These parameters analyzed by biomass, X-ray, GC, and TLC. Remarkably, saturated fatty acids, monounsaturated, and di-unsaturated fatty acids amounts, increases, while polyunsaturated fatty acids to decrease markedly. The maximum fatty acid content observed at 0.4 mgl

    Abstract A bionanocomposite based on biosynthesized poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and reinforced with silver@zinc oxide (Ag-ZnO) was synthesized in variable loadings of Ag-ZnO using the in-situ casting dissolution technique. The degradable biopolymer PHBV had been biosynthesized from date waste as a renewable carbon source. The fabricated products were investigated as promising antibacterial materials. The Ag-ZnO nanoparticles were also synthesized using the green method in the presence of Gum Arabic. The Ag-ZnO nanoparticles were loaded within the PHBV biopolymer backbone at concentration of 1%, 3%, 5% and 10%, PHBV/Ag-ZnO

    Abstract There are two well-known old American and Japanese quotes "snug as a bug in a rug” and ‘Tade kuu mushi mo suki-zuki’ which means very comfortable and everyone has their own tastes respectively, both quotes are best fit for beneficial plantmicrobes (PM) interactions. Most of the plants interact largely with diverse microorganisms in their surrounding environment but the question arises why PM interaction exist everywhere in agroecosystem with sustainability? PM interactions were occurred from the evolutionary time scale which is considered in existing literature.
