Effects of end products on fermentation profiles in Clostridium carboxidivorans P7 for syngas fermentation [PDF]

Bioresource Technology, 2016
Clostridium carboxidivorans P7 is a strict anaerobic bacterium capable of converting syngas to biofuels. However, its fermentation profiles is poorly understood. Here, various end-products, including acetic acid, butyric acid, hexanoic acid, ethanol and butanol were supplemented to evaluate their effects on fermentation profiles in C.

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.

Biomass-derived syngas fermentation into biofuels: Opportunities and challenges

Bioresource Technology, 2010
The 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 ...

Review of syngas fermentation processes for bioethanol

Biofuels, 2014
Bioethanol 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.

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.

Syngas fermentation to biofuels: Effects of ammonia impurity in raw syngas on hydrogenase activity

Biomass and Bioenergy, 2012
Abstract Hydrogenase activity plays an important role in the fermentation of biomass-generated syngas (containing CO, CO 2 , and H 2 ) to obtain ethanol and other biofuels. One process efficiency issue for producing biofuels from syngas fermentation is the ability of key cellular enzymes to produce reducing equivalents from syngas. For microbes using

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 ...

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.
