“…The use of natural laccase in the detection and degradation of phenols and anilines is often restricted by its inactivation at elevated temperature, narrow pH adaptability and high cost due to the complicated extraction procedures and low contents in organisms. 30,31 To overcome these limitations of natural enzymes, the study of artificial enzymes is becoming the focus of many recent research studies. It has been found that some inorganic nanomaterials, termed nanozymes, have exhibited enzyme-like activities with high catalytic performances and superb stability.…”

“…A non-specific extracellular enzymatic system composed of MnP, MiP, and laccase was used in the degradation of several xenobiotics, including pesticides [30]. In this study, we reported the presence of three enzymes that could influence pesticide degradation and metabolites, as reported for 3,5-DCA degradation via fungal laccase [31]. The ATZ metabolite, HA, showed a different trend, and the decrease in concentration was not as evident as that for the other metabolites; however, more time may be required to eliminate HA.…”

This study provides the basis for implementing a continuous treatment system for wastewater containing a pesticide mixture formed by atrazine, iprodione, and chlorpyrifos. Two fungal strains (Verticilium sp. H5 and Metacordyceps sp. H12) isolated from a biomixture of a biopurification system were able to remove different pesticide concentrations (10 to 50 mg L−1) efficiently from the liquid medium; however, the half-life of the pesticides was reduced and characterized by a T1/2 of 5.4 to 9.2 d for atrazine, 3.7 to 5.8 d for iprodione, and 2.6 to 2.9 d for chlorpyrifos using the fungal consortium. The immobilization of the fungal consortium in alginate bead was effective, with the highest pesticide removal observed using an inoculum concentration of 30% wv−1. The packed-bed reactor with the immobilized fungal consortium, which was operated in the continuous mode at different flow rates (30, 60, and 90 mL h−1), required approximately 10 d to achieve removal efficiency (atrazine: 59%; iprodione: 96%; chlorpyrifos: ~85%). The bioreactor was sensitive to flow rate fluctuations but was able to recover performance quickly. The pesticide metabolites hydroxyatrazine, 3,5-dichloroaniline, and 3,5,6-trichloro-2-pyridinol were produced, and a slight accumulation of 3,5,6-trichloro-2-pyridinol was observed. Nevertheless, reactor removal efficiency was maintained until the study ended (60 d).

“…Oxidation, hydrolysis, alkylation, and dealkylation reactions have been predominantly observed in the microbial degradation process [ 118 ]. Some studies that have reported enzymatic degradation are on cypermethrin by esterase and laccase [ 119 ], carbendazim by carbendazim hydrolase [ 120 ], malathion by phosphotriesterase [ 121 ], and isoproturon, procymidone, chlorpyrifos, dichlorophos, and monocrotophos by laccase [ 122 , 123 , 124 ]. The enzymatic biodegradation mechanism of pesticides is often complex, and this diverse biodegradation pathway needs further investigation to understand enzyme involvement properly.…”

Effective Usage of Biochar and Microorganisms for the Removal of Heavy Metal Ions and Pesticides

The bioremediation of heavy metal ions and pesticides is both cost-effective and environmentally friendly. Microbial remediation is considered superior to conventional abiotic remediation processes, due to its cost-effectiveness, decrement of biological and chemical sludge, selectivity toward specific metal ions, and high removal efficiency in dilute effluents. Immobilization technology using biochar as a carrier is one important approach for advancing microbial remediation. This article provides an overview of biochar-based materials, including their design and production strategies, physicochemical properties, and applications as adsorbents and support for microorganisms. Microorganisms that can cope with the various heavy metal ions and/or pesticides that enter the environment are also outlined in this review. Pesticide and heavy metal bioremediation can be influenced by microbial activity, pollutant bioavailability, and environmental factors, such as pH and temperature. Furthermore, by elucidating the interaction mechanisms, this paper summarizes the microbe-mediated remediation of heavy metals and pesticides. In this review, we also compile and discuss those works focusing on the study of various bioremediation strategies utilizing biochar and microorganisms and how the immobilized bacteria on biochar contribute to the improvement of bioremediation strategies. There is also a summary of the sources and harmful effects of pesticides and heavy metals. Finally, based on the research described above, this study outlines the future scope of this field.
