Special Issue Information

Dear Colleagues,

Due to recent advances in the field of energy storage, microbial fuel cells (MFCs) and their derivatives are being considered as a viable source of energy, to power low-power requirement applications. It is known that the inherent power production capabilities of MFCs and affiliated devices is relatively low compared to their chemical fuel cells counterparts (i.e., hydrogen fuel cells). Nevertheless, with the current progress witnessed in energy storage solutions, MFC technology is again becoming a viable option for powering low-drain electronic devices that could be employed in biomonitoring, biosensing applications and low-powered sensory devices for deployment in water or soil.

This Special Issue, entitled “Advances in Microbial Fuel Cell Technology for Wastewater Treatment and Energy Storage”, focuses on the application of MFC technology coupled to energy storage solutions. The scope of this Special Issue includes, but is not limited to, methods and/or applications in the following areas:

  • MFC technology affiliated with rechargeble energy storage devices;
  • MFC technology affiliated with capacitance or super-capacitance devices;
  • MFC technology affiliated with any other form of chemical energy storage;
  • MFCs used in sensing or environmental monitoring applications;
  • Specialized low-power electronic devices operating with MFCs or bio-electrochemical cells.

Microbiologically Influenced Corrosion (MIC) significantly endangers steel infrastructure, particularly in marine and buried environments, causing considerable economic and environmental damage. Sulphate-reducing bacteria (SRB) are primary supporters of MIC, accelerating iron corrosion through hydrogen sulfide production. Conventional mitigation strategies, including protective coatings and cathodic protection, often face challenges such as limited effectiveness against SRB and the aggressiveness of saltwater corrosion. This study explores a novel approach by directly introducing zinc oxide (ZnO) nanoparticles into the microbial medium to inhibit SRB activity and reduce MIC. Iron metal coupons were immersed in seawater under three conditions: control (seawater only), seawater with SRB, and SRB with ZnO nanoparticles. These coupons were used as electrodes in microbial fuel cells to obtain real-time voltage readings. At the same time, corrosion was evaluated using cyclic voltammetry (CV), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), mass loss, and pH measurements. Results demonstrate that ZnO nanoparticles significantly inhibited SRB growth, as confirmed by the antibiotic susceptibility test (ABST). It was revealed that the corrosion rate increased by 21.3% in the presence of SRB compared to the control, whereas the ZnO-added electrode showed a 21.7% reduction in corrosion rate relative to the control. SEM showed prominent corrosive products on SRB-exposed coupons. ZnO-added coupons exhibited a protective layer with grass-like whisker structures, and EDX results confirmed reduced sulfur and iron sulfide deposits, indicating suppressed SRB metabolic activity. ABST confirmed ZnO’s antimicrobial properties by producing clear inhibition zones. ZnO nanoparticles offer the dual benefits of antimicrobial activity and corrosion resistance by forming protective self-coatings and inhibiting microbial growth, making them a scalable and eco-friendly alternative to traditional corrosion inhibitors. This application can significantly extend the lifespan of iron structures, particularly in environments prone to microbial corrosion, demonstrating the potential of nanomaterials in combating microbiologically influenced corrosion (MIC).
