📄 Abstract（原文）
ABSTRACT Algal Microbial Fuel Cells (AMFCs) are an emerging bioelectrochemical technology that combines microbial electrogenesis and algal photosynthesis in a synergistic manner to produce electricity and treat wastewater containing organic matter. In an AMFC system, electroactive bacteria in the anodic compartment oxidize organic matter and release electrons to flow through an external circuit to the cathodic compartment, where oxygenic phototrophic microalgae consume oxygen and produce biomass. This two-chamber system not only produces clean and renewable energy but also addresses critical issues related to wastewater treatment and carbon sequestration on a global scale to mitigate the effects of climate change and fossil fuel depletion. AMFCs have been found to valorize various organic waste feedstocks effectively, converting waste into a valuable resource. The feedstocks used are varied, ranging from domestic sewage, which is rich in carbohydrates and proteins, to agricultural waste such as rice straw, sugarcane bagasse, and manure, which are rich in lignocellulose. Other feedstocks used are industrial effluent waste, which includes food processing waste such as dairy waste, brewery waste, and distillery waste, rich in chemical oxygen demand (COD). The waste is also rich in leachates from municipal waste. The waste is hydrolyzed or subjected to anaerobic digestion to support anodic spp such as Geobacter, which remove COD by 70-90%, generating 1-5 W/m². For the construction of an AMFC at the laboratory scale, cost-effective designs with transparent materials like polycarbonate or glass are used to build dual-chamber H-type or flat-plate reactors with effective volumes ranging between 100 and 500 mL. The anodes of the AMFC consist of carbon material like carbon cloth or graphite felt, with an inoculum of anaerobic sludge. The inoculum is 5-10 cm². The cathodes of the AMFC consist of algal biofilm with Chlorella vulgaris or Spirulina platensis on similar material, illuminated with LED arrays of 100-500 µmol photons m ⁻ ² s ⁻ ¹ .
