Abstract Residual antibiotics in chicken manure may interfere with the stability of anaerobic digestion (AD) and inhibit resource utilization efficiency. In this study, we aimed to enhance bio-methanation AD high-concentration sulfamethazine (SMZ) by adding metal (Fe, Co)-modified Enteromorpha -based hydrochar (Co-HC, Fe-HC). The results showed that Fe-HC Co-HC increased degree acidogenesis 1.25 times 1.58 times, respectively. maximum protein concentration EPS was 47.64% 72.5% after Co-HC. However, only demonstrated notable improvements both methane production SMZ removal Electrochemical analysis possessed a richer variety oxygen nitrogen functional groups, along superior electron exchange capabilities compared Fe-HC. Furthermore, microbiological assessments revealed enriched syntrophic bacteria (such as Syntrophomonas Mesotoga ), facilitating direct interspecies transfer (DIET) subsequently enhancing biomethane production. abundance genes involved significantly Co-HC, increase 75.86% Co1.5-HC treatment. Additionally, elimination antibiotic resistance ( sul1 , sul2 ) 65.66% This study offers theoretical foundation empirical support for synergistic improvement livestock poultry containing high concentrations, thereby helping overcome challenges posed recalcitrant substances.

Review on Mechanisms of Iron Accelerants and Their Effects on Anaerobic Digestion

Agriculture, Год журнала: 2025, Номер 15(7), С. 728 - 728

Опубликована: Март 28, 2025

Anaerobic digestion is an important technology for energy recovery from organic waste. However, methanogenesis restricted by some barriers, such as the low-speed bottleneck of interspecies electron transfer (IET), low hydrogen partial pressure limitation, trace element deficiency, etc., resulting in poor system stability and methane production. Recently, multiple iron accelerants have been employed to overcome above challenges proven effective enhancing methanogenesis. This study reviews effects (Fe0, Fe3O4 magnetite, Fe2O3 hematite, salts other accelerants) on anaerobic terms production, process microbial community elaborates mechanisms mediating direct (DIET) syntrophic methanogenic community, strong reducibility promoting methanogenesis, provision nutrient elements microorganisms, etc. The potential engineering application current research advances regarding environmental impacts are also summarized. Although exhibit positive digestion, most focuses laboratory small-scale investigations, its large-scale should be further verified. Future focus elucidating developing diverse methods different types systems, optimizing applications, exploring high-efficiency strategies accelerants.

An insight on energy production using microbial fuel cell: A microbiological perspective and electron transfer improvement

Journal of Chemical Technology & Biotechnology, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 28, 2024

Abstract Microbial fuel cells (MFCs) are sustainable energy technologies that could resolve pollution challenges brought by various activities. It can meet demand producing bioelectricity through catabolizing organic matter. Over the past two decades, research on many microbes have been used in MFCs, which intrigued researchers to explore underlying electron transfer mechanism between microbe and anode. Electron electrode microorganism occurs via different pathways: direct, indirect interspecies transfer. Shewanella Geobacter well‐known for microbe–electrode microbe–microbe This review provides an overview of significant varieties utilized MFCs simultaneous generation wastewater treatment. Mechanisms modes involved during oxidation wastes anode section highlighted. Furthermore, this also details some techniques promote extracellular efficiency is important enhanced performance MFC terms power, current remediation. A perspective be addressed effective functioning these technologies, opportunities systems scaled up associated techno‐economic analysis discussed. © 2024 Society Chemical Industry (SCI).
