“…In the test protocol, the O.D. at fixed wavelength (600 nm) was measured after 2 hours for about 24 hours, and the final spectrum and relationship was conducted between the average of duplicate assignments and a time (hours) to get the standard growth curve, 40 and assess the impact of the synthesized NPs samples on the kinetic growth of the tested S. aureus .…”

“…Pure PE is moderately translucent throughout the entire visible light range, with an absorbance peak below 300 nm. 43 The plain terpene oil has a pronounced absorbance peak between 250 and 350 nm, centered at 293 nm, which slightly moves toward lower wavelengths in the PE-based formulations, as a result of its encapsulation within β-cyclodextrin molecules. 30,44,45 Again, the higher transparency of the CD-lim containing films is seen also in Figure 2, where non-transmitted visible light is sizably reduced in case of CD-lim modification.…”

Linear low‐density polyethylene (PE) containing an inclusion complex composed of β‐cyclodextrin and d‐limonene (CD‐lim) is proposed as an innovative food wrapping material with antimicrobial features. PE/CD‐lim composites are prepared by conventional, high‐volume processing, and the optical and mechanical properties of the developed formulations appear suitable for their use as food packaging materials. Compared to plain PE, the PE/CD‐lim films have improved haze and UV–vis outcomes, but also decreased gloss values. Addition of CD‐lim slightly increases water uptake, up to levels suitable for the foreseen application. It also allows to improve performance of PE as food packaging material, since the PE/CD‐lim composites provide barrier to ultraviolet light, an added value for packaging of fatty acids‐containing food items, whose shelf life is often limited by oxidation caused by UV light. Most importantly, PE/CD‐lim composites exhibit significant antimicrobial properties against a wide range of microorganisms, including fungi and bacteria. Hence, PE films containing CD‐lim display suitable properties to play a role as active food packaging films.Highlights Development of polyethylene‐based composites containing a natural filler Composite films with enhanced antimicrobial and antifungal efficiency Improved transparency to visible light and barrier to UV of the composites

“…Nano-Ag particles tend to agglomerate at small diameters, < 20 nm, due to their large surface-to-volume ratio and high surface energy, which reduces their antibacterial activity. This difficulty has been addressed by researching silver-carriers such as titanium dioxide, zeolite, activated carbon, and silica, and these efforts have greatly increased their antimicrobial effectiveness (Abdel Maksoud et al 2021 , 2022 ; Bekhit et al 2022 ; Qasim et al 2015 ).…”

The bacterial wilt is a global destructive plant disease that initiated by the phytopathogenic Ralstonia solanacearum. This study display a novel biofabrication of silica/silver nanocomposite using Fusarium oxysporum-fermented rice husk (RH) under solid state fermentation (SSF). The biofabricated nanocomposite was characterized by XRD, UV–Vis. spectroscopy, DLS, SEM, EDX elemental mapping, and TEM analyses as well as investigated for anti-R. solanacearum activity. Response surface methodology was also processed for optimizing the biofabrication process and improving the anti-bacterial activity of the fabricated nanocomposite. Maximum suppression zone of 29.5 mm against R. solanacearum was reached at optimum RH content of 6.0 g, AgNO3 concentration of 2.50 mM, reaction pH of 6.3, and reaction time of 2 days. The anti-R. solanacearum activity of the fabricated nanocomposite was further improved by exposing the F. oxysporum strain to a gamma irradiation dose of 200 Gy. In conclusion, RH recycling under SSF by F. oxysporum could provide an innovative, facile, non-expensive, and green approach for fabricating SiO2/Ag nanocomposite that could be applied efficiently as an eco-friendly antibacterial agent to combat R. solanacearum in agricultural applications. Moreover, the developed method could serve as a significant platform for the designing of new nanostructures for broad applications.
