Abstract:
The study of direct electron transfer (DET) via electroactive microbes extends beyond energy applications and delves into environmental bioremediation. Microbes with DET capabilities play a role in the natural attenuation of pollutants in environments such as contaminated soils, sediments, and contaminated water bodies. The direct interaction with solid surfaces enables these microbes to participate in reducing various contaminants, showcasing the potential of direct electron transfer in sustainable water pollution remediation strategies. Research efforts in microbial electrochemical cells (MECs) are geared toward improving their efficiency, scalability, and economic viability. Advancements in electrode materials, microbial catalysts, and system designs contribute to optimizing MEC performance. The exploration of diverse electroactive microbes and the development of durable materials are paramount in augmenting the capabilities of MECs for inorganic pollutant detection and remediation in water systems. This chapter comprehensively addresses the integration of advanced sensing technologies into MECs, enhancing their ability to detect and quantify specific inorganic pollutants with high sensitivity and accuracy. Additionally, it emphasizes the importance of understanding the complex interplay between electroactive microbes and pollutant substrates at the molecular level for devising tailored bioremediation strategies to effectively address diverse water quality challenges.
