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.

Silver nanoparticles (AgNPs) are widely recognized for their unique optical, electronic, and antibacterial properties, enabling use in biosensing, photonics, electronics, drug delivery, antimicrobial treatments. Green chemistry-based biological synthesis methods offer an eco-friendly alternative to traditional chemical techniques. Among metallic (NPs) metal oxides, those derived from plant extracts exhibit notable medicinal properties. Due exceptional stability low reactivity, AgNPs particularly well-suited various applications. can be synthesized through chemical, physical, or methods, each with distinct benefits challenges. Chemical physical approaches often involve complex purification, reactive reagents, high energy demands, while though slower, provide sustainable solutions. The chosen method strongly influences the stability, size, purity of resulting NPs. This review emphasizes importance selecting appropriate optimize characteristics functionality silver It consolidates research spanning past two decades, including most recent findings 2024. A comprehensive electronic search databases such as PubMed, Scopus, ScienceDirect, Cochrane, Google Scholar was conducted up-to-date overview advances applications nanoparticles.
