Moringa Oleifera Based Electrode Effect on Bacteria for Glucose Oxidation

Abstract

PA is a gram-negative pathogen that is highly aggressive and known to cause several nosocomial infections, leading to significant morbidity and mortality levels.Individuals with compromised immunity are especially vulnerable to life-threatening infections caused by this bacterium.PA importance as a pathogen is further underscored by its virulence, increasing resistance to antibiotics, and its ability to adapt to diverse environmental conditions.In this study, MO extract antibacterial activity was evaluated using Ec methods, such as CV, EIS and polarization curves (Tafel's law), against pathogenic bacteria, including PA.The performance of the developed CPE modified by MO was herein tested with C6H12O6, by CV technique.The CV recorded at the CPE-MO surface showed a well-defined peak, which was due to CHO Ec oxidation.PA addition to the electrolyte solution containing CHO caused its oxidation peak to disappear.The hypothesis that PA would adhere to the CPE-MO surface, blocking the active sites and, subsequently, CHO oxidation, was proposed.To verify this hypothesis, polarization curves and EIS, which revealed the presence of a non-conductive film on the CPE-MO surface, were employed.The morphology of the elaborated electrodes surfaces was characterized by SEM.
