“…The synthesis of MgO-NPs using fungi can be achieved either by intracellular method through the transportation of metal ions inside the fungal cell and then reduced by enzymes, or extracellular method through the reacting of metal ions with fungal biomass filtrate [ 22 ]. It has been reported that MgO-NPs can be used in novel applications including the removal of toxic waste, catalysis, antimicrobial property, refractory materials and wastewater treatment, ceramics, heavy fuel oils, enhancement of the potential of antioxidant and substrate in ferroelectric thin films, biomedical fields, sensing, adsorbents, lithium batteries, and agriculture sectors [ 18 , 23 , 24 , 25 ]. MgO-NPs are characterized by long-lasting antimicrobial activity, and this phenomenon can be attributed to its ability to tolerate high temperatures and low volatility [ 26 ].…”

The metabolites of the fungal strain Rhizopus oryaze were used as a biocatalyst for the green-synthesis of magnesium oxide nanoparticles (MgO-NPs). The production methodology was optimized to attain the maximum productivity as follows: 4 mM of precursor, at pH 8, incubation temperature of 35 °C, and reaction time of 36 h between metabolites and precursor. The as-formed MgO-NPs were characterized by UV-Vis spectroscopy, TEM, SEM-EDX, XRD, DLS, FT-IR, and XPS analyses. These analytical techniques proved to gain crystalline, homogenous, and well-dispersed spherical MgO-NPs with an average size of 20.38 ± 9.9 nm. The potentiality of MgO-NPs was dose- and time-dependent. The biogenic MgO-NPs was found to be a promising antimicrobial agent against the pathogens including Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans with inhibition zones of 10.6 ± 0.4, 11.5 ± 0.5, 13.7 ± 0.5, 14.3 ± 0.7, and 14.7 ± 0.6 mm, respectively, at 200 μg mL–1. Moreover, MgO-NPs manifested larvicidal and adult repellence activity against Culex pipiens at very low concentrations. The highest decolorization percentages of tanning effluents were 95.6 ± 1.6% at 100 µg/ 100 mL after 180 min. At this condition, the physicochemical parameters of tannery effluents, including TSS, TDS, BOD, COD, and conductivity were reduced with percentages of 97.9%, 98.2%, 87.8%, 95.9%, and 97.3%, respectively. Moreover, the chromium ion was adsorbed with percentages of 98.2% at optimum experimental conditions.

“…In addition to E. coli , ROS effective inhibition of S. aureus (ZnO/V 2 O 5 ), K. pneumoniae (ZnO NPs), Enterococcus faecalis (flowerlike ZnO micro), P. aeruginosa (Cu 2 O/Ti 3 C 2 T x ), and Micrococcus luteus (flowerlike ZnO micro) have been reported. Generally, the release killing of metal ions or contact killing of NPs and the ROS disinfection mechanism co-occurred, and some reviews summarized their possible antibacterial mechanism. , Meanwhile, photosensitization, which is a photoreaction in which the main reactant is activated by interacting with a light-induced excited chemical species, is considered photocatalysis …”

Currently, serious challenges to drinking water security remain. Toxic chemicals and opportunistic pathogens can trigger a grave health risks even in areas where the water supply system is relatively ideal. Antibacterial functionalization of water treatment technologies is introduced on the basis of the safety evaluation of microorganisms and chemicals. For water purification materials themselves, the introduction of an antibacterial function effectively ensures that they are prevented from being contaminated by microorganisms during long-term use. The antibacterial function of traditional water purification technologies can be realized through some modifications. The principle of some novel antibacterial approaches is summarized, which provides new inspiration for the precise design of environmental antibacterial materials. More importantly, attention is given to antibacterial modification methods and the effects between antibacterial function and the capture and/or degradation of pollutants. The application of multifunctional antibacterial materials in the purification, transportation, and storage of drinking water is also discussed.

We used a sol–gel spin coating technique to synthesize nanocomposite thin films based on zinc oxide (ZnO) loaded with silver nanoparticles (NPs). We tested these ZnO/Ag NP photocatalysts, with a thickness of about 100 nm, for the photodegradation of the indigo carmine dye solution. The study focused on the effects of Ag NPs on the ZnO matrix as well as the impact of their concentration on the photocatalytic performance of the nanocomposite. The study also highlighted the high stability of the photocatalytic performance of these nanocomposites. This work is a contribution in the search for non-toxic thin film photocatalysts that is usable under solar radiation for the treatment of contaminated wastewater. Innovation in the field of heterogeneous photocatalysis requires the use of solar resource with efficient results in terms of photocatalytic performance.
