Synthetic biology approaches and bioseparations in syngas fermentation

Trends in Biotechnology
Fossil 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 ...

Syngas fermentation to ethanol: the effects of gas recycling on economics

2023
Syngas fermentation is a biochemical pathway to produce ethanol and has been commercialized successfully. The economic viability of this process could be further improved to become more competitive in the existing ethanol market. Improving gas utilization is the key, and can be done by recycling the unreacted syngas.

A biotechnological overview of syngas fermentation

2022
Syngas 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, 2013
Acetogenic 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, 2017
The 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

2020
In 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.

The enhancement of energy supply in syngas-fermenting microorganisms

Environmental Research
After 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, 2011
Currently, 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.

[Comparison of microorganisms fermenting syngas into ethanol].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2014
To evaluate the ability of microbial mix-culture fermenting syngas into ethanol, we studied the microbial mix-cultures A-fm 4, G-fm 4, Lp-fm 4 and B-fm 4 obtained by enrichment and compared with Clostridium autoethanogenum DSM10061 with 10% and 25% inoculation size.
