Summary: Different inoculum to slaughterhouse waste ratios influence digester performance, substrate utilization, and methane yield through microbial shifts and metabolic syntrophy. Interactions among acetogenic and acetate-oxidizing species with methanogens play a critical role in improving methanogenic activity. Syntrophic interactions among core microbiota induce major metabolic activities and quorum sensing.

Summary: The study enriched a microbial consortium capable of degrading phenanthrene under methanogenesis from paddy soil. Glucose addition increased the production rate of CH4 but did not affect phenanthrene degradation. The abundance of genes related to aromatic compound degradation decreased with glucose addition, while genes related to CH4 synthesis were unaffected. Additionally, the acetate pathway was found to be dominant in the phenanthrene-degrading system, indicating the potential for a multistage pattern to enhance PAH removal and CH4 production in anaerobic digestion.

Summary: In this study, a binary electroactive material with pseudocapacitance/conductance was designed to store-release electrons and enhance direct electron transfer between acid-producing bacteria and methanogens in anaerobic wastewater treatment. The pseudocapacitance of the material promoted ATP synthesis and provided energy for organic decomposition, while the conductance facilitated direct interspecies electron transfer and improved methane production. The material also helped buffer excess electrons and alleviate pH drop. These findings provide a strategy to enhance electron transfer in anaerobic treatment and guide the design of electroactive materials.

Summary: This study found that the addition of an appropriate amount of rice husk biochar (RHB550) can improve the anaerobic digestion process of food waste and increase methane production. However, excessive amounts of biochar can inhibit the digestion process. Adding RHB550 biochar can enhance the stability and methane yield. Increasing its concentration can further improve the organic loading rate in anaerobic digestion.

Summary: This study attempted to convert surplus hydrogen to methane through anaerobic digestion by hydrogenotrophic methanogen, aiming to overcome the drawbacks of hydrogen escaping from small or middle-scale industries. A biochemical methane potential test was conducted by injecting hydrogen and carbon dioxide directly into the reactors for 30 days. The results showed an increase in cumulative methane yield and methane content in the biogas, with a significant improvement in the quality of biogas. Microbial community analysis indicated that hydrogenotrophic methanogenesis played a dominant role in enhancing methane production.

The system could maintain high COD removal efficiency and increase methane production, with most of the organic matter removal occurring in compartments C1 and C2. The dominant species in the HABR were acetoclastic methanogen Methanosaeta and hydrogenotrophic methanogen Methanobacterium, while species capable of syntrophic partnership with methanogens were also identified.

Summary: The aim of this research was to quantify the energy demand, carbon footprint, and financial cost of sewage treatment with dissolved methane recovery. The methods used were life cycle assessment and technoeconomic analysis. The results showed that sewage treatment with methane recovery reduced energy demand by 12%, carbon footprint by 16%, and increased financial cost by 2.3%, compared to treatment without methane recovery. The highest eco-efficiency was achieved in a scenario with higher influent COD, higher COD removal efficiency, methane saturation, photovoltaic electricity supply, and higher energy efficiency in methane recovery, which reduced energy demand by 55%, carbon footprint by 66%, and financial cost by 63%.
