Abstract	'Go green' has also been implied to nanotechnology by harbouring eco-benign principle for a cleaner production of silver nanoparticles (AgNPs). This was achieved using a nitrate reducing Bacillus subtilis L1 (KT266579.1) inhabiting rhizosphere soil under optimized laboratory conditions, highlighting on its antibacterial modus operandi. Nano-characteristics and antimicrobial mechanism were investigated using spectroscopic and electron microscopic studies. Spectroscopic and microscopic characterization revealed typical surface plasmon resonance (SPR) with λ

Abstract	Essential oils (EOs) seem to be more versatile and consist of a variety of volatile and organic biological active substances that are also employed as the better substitutes in the bacteria, fungal and various food sectors. Many researchers have done detailed research about the antibacterial property of essential oils and their respective inhabitants. While several pioneering works in the past have explained the mode of action of some compounds, an extensive understanding of most of the substances and their molecular mechanisms is still lacking. In particular, the bioactivity characteristics of EOs were evaluated by the main components found in these. These components were commonly utilized in the applications of bactericidal, fungicidal, medicinal and antioxidant drugs. The oils bioactivity can be contrasted with the behavior of pharmaceutical formulations which are produced synthetically. Consequently, essential oils are showing promise organic extracts that require further analysis in the nutrition or pharmaceutical companies for potential applications as supplements, additives or antibacterial. Because of their diverse activities like antifungal and antibacterial characteristics, essential oils may be utilized as alternate additives to improve the grain and seed shelf life. This review aims to provide a summary of existing information on the antibacterial and antifungal properties of EOs, their mechanism, and ingredients in identifying the areas of study that can promote the implementation in various bacterial and fungal properties.

Abstract	Most plants, especially the leaves are considered as the hostile environment for microbial growth. The phylloplane plays an important role in the plant-microbe interactions in leaf surface for the diverse communities’ of microflora. These fungi will be a good source for analyzing metal-microbes interaction and synthesizing nanoparticles. Silver nanoparticles (AgNPs) were synthesized from Ag+ ions by treating with different extracts of the phylloplane fungus, Aspergillus tamarii with AgNO3. The appearance of yellowish brown color in the conical flasks suggested the formation of AgNPs at dark and light conditions. The AgNPs were characterized by UV–Vis spectroscopy, which has proved to be very useful for the analysis of nanoparticles. A strong surface plasmon resonance were centered at approximately 425 nm indicated the presence of silver nanoparticles analyzed by UV–Vis spectroscopy and the particle sizes were confirmed by atomic force microscopy (AFM) as 40 nm. Extracted fungal metabolites and synthesized silver nanoparticles showed good antimicrobial activity against the microbial pathogens but the fungal biomass and the AgNPs synthesized from this showed least effect in comparison to others. Candida albicans was found most susceptible to the AgNPs of Aspergillus tamarii in all fungal extracts in comparison to other bacterial strains. Among bacterial strains, Staphylococcus aureus was more affected than V. parahaemolyticus and E. coli was found resistant to the fungal extract AgNPs. The nanoparticles which exposed to sunlight was found more efficient than in dark synthesis in order to act as good antimicrobial agents against the test pathogens.

Abstract	Microplastics were found to be the major pollutant across the globe. Plastic microbeads, like 0.5 mm, are very small and mainly used for exfoliation. The marine species cannot distinguish between their usual food and these microbeads. Microbeads have the potential to transfer up the food chain, which may lead to consumption by humans in the end. Activated carbon from inexpensive sources has greatly interested separation systems, especially in water treatment. In that view, carbon nanoparticles were produced, combined with polyvinylidene fluoride (PVDF) polymer, and used as a membrane to trap the microplastic particles. UV-Vis, FTIR, TEM, and powder X-ray diffraction (XRD) analysis confirmed the produced carbon nanoparticles. FT-RAMAN Spectroscopy studies, microbial viable cell count, and turbidity analysis followed the membrane preparation and post-treatment. The carbon nanoparticle fabricated nanofilm effectively eliminates the microbial count and microplastics and reduces the turbidity (0.13 NTU). This study confirms that the membrane effectively filters microplastics and other contaminants. Nowadays, nanofiltration technologies have been considered beneficial for eliminating microplastics to an efficiency of 95%. Further research is needed to determine a feasible low-cost, ecologically suitable, and effective solution to remove the microplastics in water.

Abstract	Bacterial biomolecule-mediated nanoparticle (NP) synthesis constitutes a reliable, eco-friendly approach that ameliorates green-chemistry principles. In this study, stable silver nanoparticles were synthesized by exposing aqueous silver ions to an extracellular diffusible pigment produced by Pseudomonas aeruginosa (PA6) under optimized laboratory conditions. Spectroscopic and microscopic analyses showed the typical characteristics of silver with an average size of ∼28.30 nm and spherical shape. The particles were polydispersed and showed no definite agglomeration with a zeta potential of −32.3 mV, conferring stability. Antimicrobial studies were carried out using 5, 15, 25 and 50 μg mL−1 concentrations of pcAgNPs, which showed significant antibacterial activity toward clinically important pathogens at all concentrations compared to with the control sample. The bactericidal effect induced by pcAgNPs associated with cell damage was well demonstrated using electron microscopic studies. ROS production was measured using the DCFH-DA method and the oxidative stress was assessed by measuring the reduced glutathione (GSH) levels. Cytotoxicity studies on HEp-2 (Human Epidermoid Larynx Carcinoma) cells exposed to pcAgNPs showed dose-dependent cytotoxic effect with IC50 of 14.8 μg mL−1 compared to with IC50 of 7.38 μg mL−1 for the Vero cell control. Mechanistically, the pcAgNPs activated p53 that induced catalase, leading to apoptosis and DNA fragmentation via a p53 transcriptional pathway and electron transport arrest, which resulted in cell death. This synergistic efficacy of pigment-AgNPs demonstrated excellent antimicrobial and anti-proliferative activities, providing a potential lead for developing a broad-spectrum antibacterial agent and improving the therapeutic modalities targeting carcinoma cells at the gene level.

Abstract	New enzymatic approaches using bacteria and fungi for the synthesis of nanoparticles in both intra- and extracellular are playing an advanced key role in pharmacotherapeutics. In the present study we have reported on the use of fungus Aspergillus clavatus for the extracellular synthesis of bionanoparticles from silver nitrate (AgNO(3)) solution. The bionanoscale particles were characterized by UV-visible spectroscopy, thin layer chromatography, atomic force microscopy (AFM) and FTIR. The synthesized bionanoscale particle showed a maximum absorption in the visible region of 420 nm. The AFM study of bionanoscale particle ranged in the size of 550-650 nm. The analysis was carried out by TLC and FTIR to identify the biomolecules responsible for the bioreduction of silver ion and capping of the bioreduced silver nanoparticles. The present study analyzes the antimicrobial activity of the silver nanoparticles synthesized from A. clavatus against MRSA and MRSE, which showed the maximum activity against MRSA, followed by MRSE.
