Influence of environmental factors of long-term operation and effectiveness of SMFC-based biosensors for heavy metal polluted waters

  • 1 University of Mining and Geology, Sofia, Bulgaria


Sediment microbial fuel cells are relatively new devices, originally designed to generate electricity from the degradation of organic matter in the soil by microorganisms. Currently, SMFC-based biosensors are attracting scientific interest as new and promising devices for rapid real-time monitoring of water quality and water pollutants. Compared with conventional biosensors, SMFC-based biosensors show advantages such as low cost, simple design, and the possibility of IN SITU operation and self-powered monitoring. SMFCbased biosensors are expected to be used for remote environmental monitoring, therefore evaluating their long-term performance is crucial for their usability. In this paper, we present new data needed to establish the long-term performance of SMFC based biosensors. The present study presents the effect of various environmental factors such as temperature, pH and microbial activity on the performance and effectiveness of the SMFC based biosensor for monitoring water contaminated with heavy metals. The results show stable long-term performance of these devices under various environmental conditions.
