However, the limited rate of extracellular electron transfer (EET) and the availability of electrode materials remain key factors limiting the practical application of MFCs. In this article, modified carbon derived from cyanobacteria is applied to modify electrodes and assemble MFCs. By outputting voltage, power density, chemical oxygen demand removal rate and Coulombic efficiency the excellent bioelectricity performance of the assembled MFCs is demonstrated. The degradation performance of the assembled MFCs on various typical pollutants represented by tetracycline is illuminated, even up to 95.12%. Moreover, the pollutant removal mechanism by assembled MFCs is elucidated, including biofilm community and degradation pathway analysis. In a word, the enhanced EET process and high accessibility make the proposed MFC anode have fascinating application prospects in achieving efficient biopower generation and pollutant degradation simultaneously.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":"114 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adding granular activated carbon (GAC) increased the total nitrogen removal rate to 66.99 g-N/m3/day, compared to 50.00 g-N/m3/day in non-GAC reactor. Both reactors dominated by Candidatus Brocadia (non-GAC: 36.25 %, GAC: 35.5 %) but GAC improved specific anammox activity. Functional metabolic profiling from metagenomic analysis unveiled that GAC enhanced pathways associated with electron shuttle production, potentially promoting intra/extracellular electron transfer. In nitrogen metabolism, GAC is indicated to facilitate anammox N2H4 synthesis process, and inhibit nitrification and full denitrification processes, functioned by Nitrosomonas and Castellaniella which are more abundant in the non-GAC reactor. GAC also enhanced dissimilatory nitrate reduction to ammonium and partial denitrification processes, providing anammox with NH4+/NO, which was conducted by Anaerolineae members (29.7 % in GAC-reactor and 7.8 % in non-GAC reactor sludge).

The adsorption mechanisms and influential parameters are systematically examined to develop an insight into interactions between MOF and biochar in remedial process. The adsorption capacity of composites is generally doubled compared to the standalone biochar, while MOFs maintain their crystallinity, even over multiple regeneration cycles, indicating the composites’ long-term applicability and sustainability. These findings highlight the potential of MOF-biochar composites for environmental applications and identify key areas for further research to enhance their sustainability in environmental protection and green energy.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":"14 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142841265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
