Abstract

Microbial fuel cell (MFC) technology is considered one of the renewable sources of energy for the production of bioelectricity from waste. Due to the depletion of fossil fuels and environmental considerations, MFC haa garnered increasing importance as it is a sustainable and environmentally-friendly method of generation of bioenergy. In MFC, electroactive bacteria (EAB) and biofilms are harnessed to convert organic substances to electrical energy. Extremophiles survive in extreme environments, and they have demonstrated potential applications in microbial electrical systems (MES) and MFC technology. The key limitations of MFC are the low power output and engineering constraints of the fuel cell. Hence, it is imperative to understand the genetics, key metabolic pathways, and molecular mechanisms of the EAB for enhancing the power generation in MFC. This chapter gives a brief overview of the scope and applications of extremophiles in wastewater treatment, bioelectricity, and biohydrogen production using MFC, eventually enhancing the functional efficiency of MFC.

微生物燃料电池在可持续生物能源生产中的应用

微生物燃料电池(MFC)技术被认为是利用废弃物生产生物电的一种可再生能源。由于化石燃料的枯竭和对环境的考虑，MFC作为一种可持续和环境友好的生物能源生产方法，已经获得了越来越多的重要性。在MFC中，利用电活性细菌(EAB)和生物膜将有机物质转化为电能。极端微生物在极端环境中生存，它们在微生物电气系统(MES)和MFC技术中具有潜在的应用前景。MFC的主要限制是低功率输出和燃料电池的工程限制。因此，了解EAB的遗传、关键代谢途径和分子机制是提高MFC发电能力的必要条件。本章简要概述了极端微生物在MFC废水处理、生物发电和生物制氢等方面的范围和应用，最终提高了MFC的功能效率。
