Green synthesis of zinc oxide nanoparticles was carried out using Prosopis juliflora bark extract and Cordia dichotoma leaf with acetate precursor in the presence 2 M NaOH solution. The prepared were characterized by Powder X-ray diffraction (PXRD), UV-visible absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), Photoluminescence (PL) to study its structural optical properties. studies confirmed hexagonal wurtzite phase samples an average crystallite size calculated Scherrer equation 38.22 nm 29.95 for mediated (PJZ) (CDZ) NPs respectively. Williamson-Hall modified form uniform deformation model (UDM), stress (USDM) energy-density (UDEDM) determine micro-strain ZnO nanomaterials. Tauc’s plot method revealed energy gap value 2.86 eV PJZ sample 2.95 CDZ due quantum confinement effect. FTIR spectra recorded ascertain biomolecules involved green synthesis. PL showed a strong UV emission peak around 370 visible broad band at 554 which is singly ionized oxygen vacancies. An effective prepare nanomaterials efficient antioxidant potential reported this study. current has also demonstrated that small particle responsible significant antibacterial activity against both gram-positive gram-negative bacteria.

Biotechnological Applications of the Ubiquitous Fungus Penicillium sp. 8L2: Biosorption of Zn(II) and Synthesis of ZnO Nanoparticles as Biocidal Agents

Sustainability, Journal Year: 2025, Volume and Issue: 17(6), P. 2379 - 2379

Published: March 8, 2025

In this study, the capacity of ubiquitous filamentous fungus Penicillium sp. 8L2 to remove Zn(II) ions present in synthetic solutions was studied and optimal operating conditions were obtained based on a response surface methodology (RSM). The contact time optimized through kinetic tests. Equilibrium tests then carried out, which allowed biosorption isotherms be for several mathematical models. At same time, fungal cell extract transform metal into ZnO nanoparticles with biocidal evaluated. Its inhibitory five microbial strains determined. mechanisms nanoparticle synthesis characterized by different crystallographic, spectrophotometric microscopic analytical techniques. It confirmed that bound superficially but also periplasmic space strong bond phosphate groups, both stage during consolidation nanoparticles. addition, presence hydroxyl, amino, carbonyl methylene groups identified, could promote nanoparticles, since some them have reducing nature. kinetics showed occurred two stages, first very fast second slower. identified maximum 52.14 mg/g Langmuir model under conditions: 5 days, pH 5.6 0.2 g/L biomass dose. success biological route an average size 18 nm obtained. data good inhibition ability against tested microorganisms, values ranging from 62.5 1000 µg/mL. is promising microorganism field heavy applied biotechnology.
