“…In addition, algal propagations is considered as an indicator of water quality; as the availability of some contaminants such as nitrate and phosphate leads to eutrophication and alterations in the biology and chemistry of the aquatic eco‐systems. However, the unwanted proliferation of algal weeds accompanied with other microbial scums may result in fouling of water bodies with unpleasant odors …”

Microbial pollution of water is one of the hazardous factors that threaten public health and the surrounding ecosystem. Therefore, the development of environmentally benign nanoparticles with exceptional properties has increased the drive toward improvement of water/wastewater disinfection. Accordingly, we aim to address the antagonistic effect of biogenic hematite nanoparticles (HNPs) against a broad spectrum of microorganisms and in water/wastewater disinfection systems. The minimum inhibitory concentration of HNPs at a range of 0.075–9.6 mg mL−1 is examined. The results demonstrate that Gram‐positive bacteria are more susceptible to HNPs than Gram‐negative ones. In addition, the growth of Candida albicans and Aspergillus brasiliensis is inhibited by applying 1.2 mg mL−1 of HNPs, which indicates antifungal activity. Moreover, HNPs (0.3 mg mL−1) inhibits 58.7, 50.5, and 86.3% of the growth of Staphylococcus aureus, Pseudomonas aeruginosa biofilms, and Chlorella vulgaris, respectively. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) of untreated and HNPs‐treated cells of Escherichia coli, Staphylococcus aureus, Clostridium perfringens, Candida albicans, and Chlorella vulgaris are studied, and the ultrastructure micrographs show ultrastructure deformities caused by HNPs. Remarkable disinfection strength reaches up to 99.8%, mainly with increasing dose and contact time. The current study highlights the efficiency of HNPs as a biocide, which could contribute to water/wastewater treatment as an alternative for chlorine.

Important gaps in knowledge remain regarding the potential of nanoparticles (NPs) for plants, particularly the existence of helpful microorganisms, for instance, arbuscular mycorrhizal (AM) fungi present in the soil. Hence, more profound studies are required to distinguish the impact of NPs on plant growth inoculated with AM fungi and their role in NP uptake to develop smart nanotechnology implementations in crop improvement. Zinc ferrite (ZnFe2O4) NPs are prepared via the citrate technique and defined by X-ray diffraction (XRD) as well as transmission electron microscopy for several physical properties. The analysis of the XRD pattern confirmed the creation of a nanocrystalline structure with a crystallite size equal to 25.4 nm. The effects of ZnFe2O4 NP on AM fungi, growth and pigment content as well as nutrient uptake of pea (Pisum sativum) plants were assessed. ZnFe2O4 NP application caused a slight decrease in root colonization. However, its application showed an augmentation of 74.36% and 91.89% in AM pea plant shoots and roots’ fresh weights, respectively, compared to the control. Moreover, the synthesized ZnFe2O4 NP uptake by plant roots and their contents were enhanced by AM fungi. These findings suggest the safe use of ZnFe2O4 NPs in nano-agricultural applications for plant development with AM fungi.
