Improved efficiency of anaerobic digestion through direct interspecies electron transfer at mesophilic and thermophilic temperature ranges

Graphene Facilitates Biomethane Production from Protein-Derived Glycine in Anaerobic Digestion

“…Microbial electron transfer between electron-producing acidogens and electron-consuming methanogens in AD might proceed via either DIET or MIET (with hydrogen as an electron carrier). To compare the electron transfer efficiencies of DIET and MIET, previous models have been proposed based on the Nernst equation and Fick's diffusion law ( Cruz Viggi et al., 2014 , Lin et al., 2017 , Lin et al., 2018 ). Using ethanol as the substrate in AD, Lin et al.…”

“…Renewable pyrogenic carbon has shown the capability of directly transferring electrons ( Sun et al., 2017 ), suggesting a cost-effective application of DIET. To illustrate the dynamic advantages of DIET over MIET in AD, simplified models have been proposed to calculate the maximum potential of electric current ( Cruz Viggi et al., 2014 , Lin et al., 2017 , Lin et al., 2018 ). Cruz Viggi et al.…”

Direct interspecies electron transfer in anaerobic digestion: Research and technological application

“…除了Methanothrix和Methanosarcina, 在一些投加 导电材料或少量乙醇的产甲烷复杂环境中还检出了一 些具备分泌导电菌丝或细胞色素OmcS的能力的产甲 烷菌, 如Methanobacterium [53] 、Methanospirillum [46] 、 Methanococcus [54] 、Methanoregula [37] 、Methanolinea [55] 、Methanosphaerula [44] 、Methanomassiliicoccus [41,56] 、Methanothermobacter [41] 和Methanoculleus [57] , [58] , 而从固体金属表面接受电子的 http://engine.scichina.com/doi/10.1360/TB-2020-0661…”

“…在此之前, DIET被认为是处理啤酒废 水的UASB反应器颗粒污泥内微生物互养代谢的主要 工作模式 [16] , 且颗粒活性炭可明显加快该颗粒污泥中 互养代谢 [18] . 此外, Lin等人 [56] 投加石墨烯至处理乙醇 的中温(35°C)和嗜热(55°C)厌氧消化器发现, 其甲烷产 生速率提高20%以上. Zhao等人 [27] .…”

İletken Malzemeleri̇n Kati Organi̇k Atiklardan Bi̇yogaz Üreti̇mi̇ne Etki̇si̇

“…Biyoyakıtlar, atıklardan elde edilen ve fosil yakıtlara alternatif olabilecek, umut verici bir yenilenebilir enerji kaynağıdır [1]. Bir biyoyakıt olan biyogaz; her türlü organik atığın işlenmesiyle elde edilen temiz, çevre dostu ve oldukça verimli bir alternatif olarak karşımıza çıkmaktadır [2]. Dünya genelinde atıklardan biyogaz üretimi, küçük-orta ve büyük ölçekli uygulamalarla, atık değerlendirme konusunda yaygın olarak kullanılan bir tekniktir.…”
