Metabolic engineering of Clostridium ljungdahlii for the production of hexanol and butanol from CO2 and H2

Microbial Cell Factories, 2022
Background The replacement of fossil fuels and petrochemicals with sustainable alternatives is necessary to mitigate the effects of climate change and also to counteract diminishing fossil resources. Acetogenic microorganisms such as Clostridium spp. are

A deeply branching thermophilic bacterium with an ancient acetyl-CoA pathway dominates a subsurface ecosystem. [PDF]

PLoS ONE, 2012
A nearly complete genome sequence of Candidatus 'Acetothermum autotrophicum', a presently uncultivated bacterium in candidate division OP1, was revealed by metagenomic analysis of a subsurface thermophilic microbial mat community.

A Synthetic Acetyl-CoA Bi-cycle Synergizes the Wood-Ljungdahl Pathway for Efficient Carbon Conversion in Syngas Fermentation [PDF]

, 2020
Abstract The Wood-Ljungdahl pathway (WLP) is a natural carbon fixation pathway capable of converting one-carbon (C1) compounds (CO2, CO, formate) to two-carbon (C2) metabolite acetyl-CoA or coordinating with canonical glycolysis to convert sugar feedstocks to acetyl-CoA with high carbon yield.

Domestication of the novel alcohologenic acetogen Clostridium sp. AWRP: from isolation to characterization for syngas fermentation

Biotechnology for Biofuels, 2019
Background Gas-fermenting acetogens have received a great deal of attention for their ability to grow on various syngas and waste gas containing carbon monoxide (CO), producing acetate as the primary metabolite. Among them, some Clostridium species, such

Production of biofuels from C1‐gases with Clostridium and related bacteria—Recent advances

Microbial Biotechnology, 2023
Clostridium spp. are suitable for the bioconversion of C1‐gases (e.g., CO2, CO and syngas) into different bioproducts. These products can be used as biofuels and are reviewed here, focusing on ethanol, butanol and hexanol, mainly.

Metaproteomics reveals methyltransferases implicated in dichloromethane and glycine betaine fermentation by ‘Candidatus Formimonas warabiya’ strain DCMF

Frontiers in Microbiology, 2022
Dichloromethane (DCM; CH2Cl2) is a widespread pollutant with anthropogenic and natural sources. Anaerobic DCM-dechlorinating bacteria use the Wood–Ljungdahl pathway, yet dechlorination reaction mechanisms remain unclear and the enzyme(s) responsible for ...

Genome-guided analysis of physiological and morphological traits of the fermentative acetate oxidizer Thermacetogenium phaeum

BMC Genomics, 2012
Background Thermacetogenium phaeum is a thermophilic strictly anaerobic bacterium oxidizing acetate to CO2 in syntrophic association with a methanogenic partner. It can also grow in pure culture, e.g., by fermentation of methanol to acetate.

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...
