Intermittent electro field regulated mutualistic interspecies electron transfer away from the electrodes for bioenergy recovery from wastewater

Pathways to Water Sector Decarbonization, Carbon Capture and Utilization

“…When further considering the inherent property of solar light, as one of the most credible discretions, that endows the day-night intermittency but also as the potential limitation, solar intermittent driven-powered energy was also revealed that could effectively facilitate bioenergy recovery and simultaneous wastewater treatment. Wang et al (2020cWang et al ( , 2020d) demonstrated that natural solar light, as a day/night intermittent power, could effectively enhance CH 4 production from wastewater and regulate electron transfer protein of cytochrome c, and this study further displayed the underlying impact of solar energy to electrochemically enhanced AD. Wang et al (2022a) further developed natural solar-powered microbes to reduce CO 2 into CH 4 for efficient carbon capture.…”

“…Wang et al (2020c) developed natural solar-powered EM to recover CH 4 from the wastewater and demonstrated that the solar-intermittent driving mode displayed excellent higher CH 4 production and the efficiencies of electron transfer and energy recovery (Figure 13.5a). In addition, the result of molecular ecological networks (MEN) analysis disclosed that electroactive microorganisms (EAMs) played a pivotal role in three positions (bioanode, biocathode and suspension), and greatly electrochemically communicated with methanogens (Figure 13.5b) (Wang et al, 2020d). Also, hydrogenotrophic methanogens, mainly the genera of Methanobacterium and Methanobrevibacter, endowed more links and exhibited a more positive connection in bioelectrodes.…”

Renewable electron-driven bioinorganic nitrogen fixation: a superior route toward green ammonia?

“…100 For example, mixed culture species might compete for a finite matrix, presumably bringing about the extinction of one of the microbial species and thereby lowering the richness and diversity of microbial ecosystems. 101,102 Control algorithms aimed at regulating such a co-population must consider the relationship between two species while making decisions that would secure their survival and, as a result, benefits from bioengineers. In addition, exogenous mediators for promoting indirect electron transfer in bioelectrocatalysis will also bring an underlying obstacle: downstream removing and recycling redox mediators from the fermentation broth.…”

Oak-inspired anti-biofouling shape-memory unidirectional scaffolds with stable solar water evaporation performance

“…49,50 Microbes distribute in most of the real water such as seawater, 51 river water, 52 city sewage, 53 groundwater and industrial waste water. 54,55 Microbial cells should multiplicate, colonize, and attach to the water purification materials, 56,57 resulting in the deterioration of their performance and increasing economic cost during solar evaporation. For instance, our previous study has demonstrated that the water evaporation rates…”
