Industrial workplaces, particularly those involved in ore processing or smelting, pose a high risk of exposure to cadmium, a highly toxic metal. This study isolated and identified eight cadmium-resistant strains from industrial wastewater for their ability to resist cadmium. Enterobacter roggenkampii FACU2 demonstrated exceptional cadmium removal capabilities during our analysis, successfully eliminating 62% of the cadmium.

An advanced hybrid nanocomposite based on different metals (copper, cobalt, and chromium) decorated with sustainable polysaccharides (gelatin, GLN, and hydroxyethyl cellulose, HEC) was developed. The composite reflects several advantages including a controlled particle size, particle size distribution, along with promising antimicrobial and anticancer activities. Topographical and elemental analyses were carried out using field-emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), and energy dispersive X-ray analysis (EDX), demonstrating the formation of trimetallic nanoparticles (NPs) possessing domain sizes of 169 nm and 102 nm assigned to the free nanocomposite (Fcomp) and loaded nanocomposite (Lcomp), respectively.

  • Some plant species can create new microenvironments that significantly affect the cover and diversity of other plants in urban settings.
  • This study focused on the impact of a specific species (L.) on urban vegetation by analyzing 70 plots with and without this species, measuring factors like species richness and biomass.
  • Findings showed that the presence of the species led to decreased cover and diversity of associated weeds, potentially due to reduced solar radiation, soil temperature, and nutrient availability, along with some allelopathic effects on certain plant species.

In the current study, endophytic was used for the biosynthesis of silver nanoparticles (Ag-NPs) for the first time. The characterizations were performed using X ray diffraction (XRD), Transmission electron microscopy (TEM), Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX), Dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FT-IR), and UV-Vis spectroscopy. The obtained results demonstrated the successful formation of crystalline, spherical Ag-NPs with particle diameters ranging from 16 to 31 nm.

We have previously reported that squalene overproducing yeast self-downregulate the expression of the ethanol pathway (non-essential pathway) to divert the metabolic flux to the squalene pathway. In this study, the effect of co-production of squalene and ethanol on other non-essential pathways (fusel alcohol pathway, FA) of was evaluated. However, before that, 13 constitutive promoters, like and were engineered using transcription factor bindings sites from strong promoters (-300 to -669 bp) and (-300 to -579 bp), and employed to co-overexpress squalene and ethanol pathways in The FSE strain overexpressing the key genes of the squalene pathway accumulated 56.
