Bioethanol Production via Syngas Fermentation

MATEC Web of Conferences, 2018
Bioconversion of C-1 carbon in syngas through microbial fermentation presents a huge potential to be further explored for ethanol production. Syngas can be obtained from the gasification of lignocellulosic biomass, by which most of carbon content of the ...

A Two-Stage Continuous Fermentation System for Conversion of Syngas into Ethanol

Energies, 2013
We have established a two-stage continuous fermentation process for production of ethanol from synthesis gas (syngas) with Clostridium ljungdahlii. The system consists of a 1-L continuously stirred tank reactor as a growth stage and a 4-L bubble column ...

Effect of pH and pressure on syngas fermentation by anaerobic mixed cultures [PDF]

, 2013
Syngas fermentation by mesophilic anaerobic mixed cultures was studied, regarding the effect of initial medium pH (5.8, 6.9 and 7.6) and total initial syngas pressure (1.0, 1.75 and 2.5 atm) in methane production and other alternative products (acids and

A novel experimental method to determine substrate uptake kinetics of gaseous substrates applied to the carbon monoxide‐fermenting Clostridium autoethanogenum

Biotechnology and Bioengineering, Volume 121, Issue 4, Page 1324-1334, April 2024.
This article describes a combination of static and dynamic cultivation of Clostridium autoethanogenum to study the substrate uptake kinetics of the gaseous substrate carbon monoxide. A steady‐state chemostat culture was periodically disturbed with 1‐h pulses of increased carbon monoxide partial pressures, up to 1.2 atm.

The genetic basis of energy conservation in the sulfate-reducing bacterium Desulfovibrio alaskensis G20. [PDF]

, 2014
Sulfate-reducing bacteria play major roles in the global carbon and sulfur cycles, but it remains unclear how reducing sulfate yields energy. To determine the genetic basis of energy conservation, we measured the fitness of thousands of pooled mutants of

Adaptive laboratory evolution of Clostridium autoethanogenum to metabolize CO2 and H2 enhances growth rates in chemostat and unravels proteome and metabolome alterations

Microbial Biotechnology, Volume 17, Issue 4, April 2024.
Adaptive laboratory evolution was used in this study to improve Clostridium autoethanogenum's growth on CO2 and H2. The growth rate improved using various methods, where one using a 2% CO gas mixture retained the most ethanol produciton – Evolved D. Under the same CO2 and H2 chemostat conditions, no changes in rates and titres were found between the ...

Discovery of a new metal and NAD⁺-dependent formate dehydrogenase fromClostridium ljungdahlii

Preparative Biochemistry & Biotechnology, 2018
Over the next decades, with the growing concern of rising atmospheric carbon dioxide (CO2) levels, the importance of investigating new approaches for its reduction becomes crucial. Reclamation of CO2 for conversion into biofuels represents an alternative and attractive production method that has been studied in recent years, now with enzymatic methods ...

Electrobiocorrosion by microbes without outer‐surface cytochromes

mLife, Volume 3, Issue 1, Page 110-118, March 2024.
Abstract Anaerobic microbial corrosion of iron‐containing metals causes extensive economic damage. Some microbes are capable of direct metal‐to‐microbe electron transfer (electrobiocorrosion), but the prevalence of electrobiocorrosion among diverse methanogens and acetogens is poorly understood because of a lack of tools for their genetic manipulation.
