A biotechnological overview of syngas fermentation
2022Syngas is produced through thermochemical conversion from different types of wastes and is considered an energy vector for a sustainable energy future. The use of gas-fermenting microorganisms is a key factor in the ex situ fermentation of syngas to ensure a compatible concentration for the natural gas grid. Methanogenic archaea grow on syngas (CO, CO2,

Bacterial synthesis gas (syngas) fermentation
Environmental Technology, 2013Acetogenic bacteria employing the Wood-Ljungdahl pathway can be used as biocatalysts in syngas fermentation for the production ofbiofuels such as ethanol or butanol as well as biocommodities such as acetate, lactate, butyrate, 2,3 butanediol, and acetone.

Overcoming the energetic limitations of syngas fermentation
Current Opinion in Chemical Biology, 2017The fermentation of synthesis gas (including carbon monoxide, carbon dioxide, and hydrogen) with anaerobic acetogens is an established biotechnological process that has recently been transferred to a commercial scale. The natural product spectrum of acetogens is natively restricted to acetate, ethanol, and 2,3-butanediol but is rapidly expanding to ...

Biochemical Aspects of Syngas Fermentation
2020In the current scenario, the world is facing a shortage of fuels, and in the future, the existing reservoirs of fuels will be exhausted; this challenging situation could be solved by the method of syngas fermentation. Syngas is a mixed composition of gases including carbon monoxide, hydrogen and a lesser amount of carbon dioxide.

Review of syngas fermentation processes for bioethanol
Biofuels, 2014Bioethanol is recognized as an important renewable and sustainable transportation fuel. Although synthesis gas (syngas: CO, H2, CO2) produced from lignocellulosic biomass (forest or agricultural biomass) is being used in the production of bioethanol by both chemical catalytic and biosynthetic processes, the latter are noted to have more advantages.

Biomass-derived syngas fermentation into biofuels: Opportunities and challenges
Bioresource Technology, 2010The conversion of biomass-derived synthesis gas (or syngas in brief) into biofuels by microbial catalysts (such as Clostridium ljungdahlii, Clostridium autoethanogenum, Acetobacterium woodii, Clostridium carboxidivorans and Peptostreptococcus productus) has gained considerable attention as a promising alternative for biofuel production in the recent ...

Synthetic biology approaches and bioseparations in syngas fermentation
Trends in BiotechnologyFossil fuel use drives greenhouse gas emissions and climate change, highlighting the need for alternatives like biomass-derived syngas. Syngas, mainly H2 and CO, is produced via biomass gasification and offers a solution to environmental challenges. Syngas fermentation through the Wood-Ljungdahl pathway yields valuable chemicals under mild conditions ...

The enhancement of energy supply in syngas-fermenting microorganisms
Environmental ResearchAfter the second industrial revolution, social productivity developed rapidly, and the use of fossil fuels such as coal, oil, and natural gas increased greatly in industrial production. The burning of these fossil fuels releases large amounts of greenhouse gases such as CO2, which has caused greenhouse effects and global warming.

A thermodynamic analysis of electron production during syngas fermentation
Bioresource Technology, 2011Currently, syngas fermentation is being developed as one option towards the production of biofuels from biomass. This process utilizes the acetyl-CoA (Wood-Ljungdahl) metabolic pathway. Along the pathway, CO and CO(2) are used as carbon sources. Electrons required for the metabolic process are generated from H(2) and/or from CO.
