Abstract

This article focuses on the production and characterization of laminar biochar derived from longitudinal cuts of Guadua angustifolia Kunth bamboo culms, used as substrates for titanium dioxide (TiO₂) deposition to achieve photocatalytic activity against Escherichia coli 226 and Salmonella Typhimurium 211. Longitudinal cuts from mature and dry culm sections with high fibre content (notably bottom mature, middle dry, and top dry) were selected for modified pyrolysis treatments to produce stable laminar biochar with preserved mechanical strength and thermal stability. TiO₂ was deposited by sedimentation onto these biochar substrates, and under UV_253nm irradiation, the composites demonstrated significant bacterial inactivation, particularly achieving over 90% inactivation of Salmonella Typhimurium 211 on bottom mature culm biochar. The study highlights the potential of using Guadua bamboo derivatives as sustainable, bio-based materials for advanced wastewater treatment through photocatalysis.
