Bioreactor modelling for syngas fermentation: Kinetic characterization
Food and Bioproducts Processing, 2022A dynamic-kinetic model for gas fermentation of C. carboxidivorans is presented. The model described the acid/alcohol production in gas-fed stirred tank reactors (GFSTR) and in batch pressurized reactors. The model took into account gas-liquid mass transfer rate, carbon monoxide uptake rate and three conversion paths: cell growth associated with acid ...

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.

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.

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 ...

Effect of functionalized MCM41 nanoparticles on syngas fermentation
Biomass and Bioenergy, 2010Abstract MCM41 nanoparticles with or without mercaptopropyl functional groups were added to a synthesis gas fermentation reactor to investigate their influence on syngas fermentation. Carbon monoxide was fermented using Rhodospirillum rubrum (R. rubrum) , resulting in an enhanced H 2 concentration in the product gas as a result of a biologically ...

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.
