Green Biosynthesis of Zinc Oxide Nanoparticles Using Pluchea indica Leaf Extract: Antimicrobial and Photocatalytic Activities

Molecules, Год журнала: 2023, Номер 28(12), С. 4679 - 4679

Опубликована: Июнь 9, 2023

Nanotechnology is playing a critical role in several essential technologies with nanoscale structures (nanoparticles) areas of the environment and biomedicine. In this work, leaf extract Pluchea indica was utilized to biosynthesize zinc oxide nanoparticles (ZnONPs) for first time evaluated antimicrobial photocatalytic activities. Different experimental methods were used characterize biosynthesized ZnONPs. The ZnONPs showed maximum Ultraviolet-visible spectroscopy (UV-vis) absorbance at wavelength 360 nm. X-Ray diffraction (XRD) pattern exhibits seven strong reflection peaks, average particle size 21.9 Fourier-transform infrared (FT-IR) spectrum analysis reveals presence functional groups that help biofabrication. existence Zn O confirmed by Energy-dispersive X-ray (EDX) morphology SEM images. Antimicrobial studies have efficacy against Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis, Bacillus subtilis, Staphylococcus aureus, Candida albicans Cryptococcus neoformans where inhibition zones concentration 1000 µg/mL 21.83 ± 0.76, 13.0 1.1, 14.9 0.85, 24.26 17.0 1.0, 20.67 0.57 19.0 1.0 mm respectively. Under both dark sunlight irradiation, activity towards degradation thiazine dye (methylene blue-MB). Approximately 95% MB broken down pH 8 after 150 min exposure. aforementioned results, therefore, suggest synthesized implementing environmentally friendly techniques can be employed variety environmental biomedical applications.

Abstract Nowadays, extended spectrum β-lactamase (ESBL) producing Escherichia coli has been recognized and recorded worldwide as one of the main causing agents a major contributor to nosocomial infections. The current study aimed isolate detect β-lactamase-producing E. use it in extracellular biosynthesis iron oxide nanoparticles (Fe 2 O 3 NPs). Fifteen Gram-negative (G-ve), lactose-fermenting, negative citrate non-spore-forming coliform bacteria were isolated from total bacterial isolates water samples. Different tests performed including chromogenic methods acidimetric iodometric techniques phenotypic cloverleaf test Masuda double-disc test. ESBL-producing was detected confirmed by modified double disc synergy using ceftazidime, cefotaxime, ceftriaxone, amoxicillin combined with clavulanic acid, imipenem, cefepime, cefoxitin. quantitative assay done micro-iodometric assay. Among isolates, S1B1 (the highest activity) selected tested for Fe NPs. produced (NPs) characterized UV–visible spectroscopy, X-ray diffraction analysis, Fourier-transform infrared spectroscopy (FTIR), transmission electron microscope Zeta analysis. Results successful NPs which displayed an absorption peak at 346 nm crystallographic lattice plane (104). negatively charged spherical-shaped average size ≈ 24 ± nm. FTIR refers presence NPs-associated proteins act stabilizing capping agents. Antibacterial activity against Staphylococcus aureus ATCC25923, Bacillus cereus ATCC6633 (G+ve bacterium), Pseudomonas aeruginosa ATCC27853 (G-ve well strain. revealed moderate strong antibacterial action strains minimum inhibition concentration (MIC) ranging 25 40 µg/ml.
