|a Industrialization and globalization have upsurged the transition from fossil fuels utilisation to renewable energy sources. Herein, harnessing magnetised nanomaterials to bioconvert wastewater anaerobically into biogas has a great potential to be an alternative green energy source. Therefore, this study engineered and explored chitosan magnetite (nCM) and chitosan-titania magnetite (nCTM) as biocatalysts for bioremediation of wastewater with methanogenic activity enhancement. The biochemical methane potential (BMP) test setups were anaerobically run for 21 days at a mesophilic temperature of 40 °C. At a high magnification of 10 kV and a micrograph scale of 5 µm, scanning electron microscopy/energy-dispersive X-ray (SEM/EDX), withimaging revealed monodisperse surface morphology of 5.0–5.3 mm. The nCTM was found to be a very potent biocatalyst with a biostimulation effect on biogas production and methanogenic activity at a 75% degree of degradation. This resulted in biogas production of 215 mL/day and 190 mL/day for the bioreactors charged with nCM and nCTM, respectively as compared with the control of 65 mL/day. The modified Gompertz model favoured the data collected kinematically. Finally, our research showed that developing nano-biocatalysts can provide viable alternatives to traditional anaerobic biogas production in wastewater treatment settings. © 2022
