“…Various studies have demonstrated that the combination of a bioaugmentation and biostimulation approach yielded better results for atrazine removal as well as for other contaminants (El-Bestawy et al 2014;Aliyu et al 2023). Therefore, bioaugmentation with a consortium of selected bacteria coupled with biostimulation may be the best bioremediation technique since it is an effective, low-cost and environmentally friendly approach for the decontamination of atrazinecontaminated matrices and may also be used to remove many other TrOCs (El-Bestawy et al 2014;Aliyu et al 2023).…”

It is generally accepted that some trace organic contaminants (TrOCs) pass through the wastewater treatment process without being properly treated and find their way into waterbodies. These molecules can also be concentrated within the biosolids (BS) through adsorption. The presence of TrOCs in BS, which are then commonly used as soil amendments in agriculture, may affect plant growth and viability. The potential risks posed by TrOCs are being usually ignored because they are present in low concentrations and mostly have relatively short half-lives. However, the continuous addition of these substances in water sources and on farmlands makes them pseudo-persistent. To reduce the concentrations of selected TrOCs from these BS, Pseudomonas yamanorum LBUM636 (PY) was tested with and without a commercial bacterial blend of Bacillus spp. (BC). About 60% removal of atrazine was achieved using PY-amended BS. Bioslurries inoculated with PY had relatively high laccase activity at about 2,200 U/L. Laccase activity was seven times higher in samples where BC was also present, which suggests a synergistic effect between BC and PY. Concentrations of phenazine-1-carboxylic acid, an antibiotic with a biopesticide effect, were also relatively important in PY-inoculated bioslurries.

Chlorpyrifos is an endocrine disruptor pesticide that induces breast cancer cell proliferation through Estrogen receptor alpha pathway in humans. It also has toxic effects on some beneficial insects like bees, wasps, and arthropods, even low levels of CP can kill fish in water. Thus, it is important to efficiently remove this compound from wastewaters to get rid of its hazardous effects. Al2O3 supported ZnO.MoO3 composite was prepared as an efficient material for photo‐degradation of chlorpyrifos under UV irradiation and characterized by SEM‐EDX, XRD and TG techniques. The XRD analysis showed the orthorhombic structures with band gap of 2.86 eV for ZnO.MoO3/Al2O3 which was 2.96 eV for MoO3/Al2O3. The kinetics of degradation depicted that ZnO.MoO3/Al2O3 afforded a complete degradation of chlorpyrifos with half life of only 3 minutes which otherwise was 24 minutes in the presence of MoO3/Al2O3. The complete mineralization of chlorpyrifos was confirmed by GC/MS analysis, where no peaks of intermediates were recorded. The prepared material also exhibited good recyclability without any leaching of Zn and Mo metals. Thus, ZnO.MoO3/Al2O3 is an efficient and cost effective material for removal of chlorpyrifos. Its potential may also be explored for the removal of other hazardous organic pollutants.
