“…In contrast to the acetoclastic methanogenic pathway, hydrogenotrophic methanogenesis in a MEC system transforms CO 2 and H 2 into CH 4 (Figure b). ,− Hydrogenotrophic methanogens include Methanocorpusculum , Methanosphaera , Methanobacterium , and Methanoculleus . Notably, according to the literature, the CH 4 content always increases with a concurrent decrease in H 2 and CO 2 production .…”

Hydrogen gas (H2) is an attractive fuel carrier due to its high specific enthalpy; moreover, it is a clean source of energy because in the combustion reaction with oxygen (O2) it produces water as the only byproduct. The microbial electrolysis cell (MEC) is a promising technology for producing H2 from simple or complex organics present in wastewater and solid wastes. Methanogens and non-archaeal methane (CH4)-producing microorganisms (NAMPMs) often grow in the MECs and lead to rapid conversion of produced H2 to CH4. Moreover, non-archaeal methane production (NAMP) catalyzed by nitrogenase of photosynthetic bacteria was always overlooked. Thus, suppression of CH4 production is required to enhance H2 yield and production rate. This review comprehensively addresses the principles and current state-of-the-art technologies for suppressing methanogenesis and NAMP in MECs. Noteworthy, specific strategies aimed at the inhibition of methanogenic enzymes and nitrogenase could be a more direct approach than physical and chemical strategies for repressing the growth of methanogenic archaea. In-depth studies on the multiomics of CH4 metabolism can possibly provide insights into sustainable and efficient approaches for suppressing metabolic pathways of methanogenesis and NAMP. The main objective of this review is to highlight key concepts, directions, and challenges related to boosting H2 generation by suppressing CH4 production in MECs. Finally, perspectives are briefly outlined to guide and advance the future direction of MECs for production of high-purity H2 based on genetic and metabolic engineering and on the interspecific interactions.

“…Kumar et al (2018) [186] demonstrated the use of dark fermentation to optimize biomass utilization by integrating it with advanced electrochemical and oxidative processes. Similarly, Nguyen et al (2020) [187] applied dark fermentation to algal biomass and combined it with a microbial electrolysis cell to improve yield and overall efficiency.…”

“…Furthermore, several microbial species transform organic substrates in fermentative processes to produce hydrogen [65,76,187,230]. Such processes can occur in the absence or presence of light and are known as dark fermentation and photofermentation, respectively [44,225,231].…”

“…However, it faces significant challenges, including the need for large amounts of biomass to compete with food production, the impact on ecosystems through land conversion, and increased water consumption [119,153,185,231]. Furthermore, the efficiency and competitiveness of the process, the management of by-products, and the impact on biodiversity are relevant concerns [156,185,187,205]. An integrated approach and sustainable practices at all stages are essential to maximize environmental benefits and effectively contribute to more sustainable energy sources and climate change mitigation [44,193,203,237].…”

Fermentation is an oxygen-free biological process that produces hydrogen, a clean, renewable energy source with the potential to power a low-carbon economy. Bibliometric analysis is crucial in academic research to evaluate scientific production, identify trends and contributors, and map the development of a field, providing valuable information to guide researchers and promote scientific innovation. This review provides an advanced bibliometric analysis and a future perspective on fermentation for hydrogen production. By searching WoS, we evaluated and refined 62,087 articles to 4493 articles. This allowed us to identify the most important journals, countries, institutions, and authors in the field. In addition, the ten most cited articles and the dominant research areas were identified. A keyword analysis revealed five research clusters that illustrate where research is progressing. The outlook indicates that a deeper understanding of microbiology and support from energy policy will drive the development of hydrogen from fermentation.

“…Researchers in the field of energy fuels have split the microbially-driven digestion of organic biomass between the terms "fermentation" and "anaerobic digestion" depending on whether the target is the production of ethanol or biogas, respectively (Buschmann et al, 2017;Chye et al, 2018).. Even the most recent publications on biofuels research highlights important factors that make seaweeds a desirable fermentation substrate (Nguyen et al, 2020). Some of these include high (>80%) water content, which makes them readily suitable for wet biomass processes, and high energy-to-area yields as an aquaculture cultivation, with ratios comparable to maize (Allen et al, 2015;.…”
