The Complete Genome Sequence of Clostridium aceticum: a Missing Link between Rnf- and Cytochrome-Containing Autotrophic Acetogens [PDF]

, 2015
Clostridium aceticum was the first isolated autotrophic acetogen, converting CO2 plus H2 or syngas to acetate. Its genome has now been completely sequenced and consists of a 4.2-Mbp chromosome and a small circular plasmid of 5.7 kbp.

Formate Is Required for Growth of the Thermophilic Acetogenic Bacterium Thermoanaerobacter kivui Lacking Hydrogen-Dependent Carbon Dioxide Reductase (HDCR)

Frontiers in Microbiology, 2020
The hydrogen-dependent carbon dioxide reductase is a soluble enzyme complex that directly utilizes hydrogen (H2) for the reduction of carbon dioxide (CO2) to formate in the first step of the acetyl-coenzyme A- or Wood-Ljungdahl pathway (WLP).

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Impact of conductive magnetite nanoparticles and anode polarization on glucose fermentation

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 5, Page 1027-1034, May 2026.
Abstract BACKGROUND Electrically conductive materials and electrochemical stimulation strategies are increasingly explored to steer microbial fermentation towards desired metabolic outputs. These approaches also hold remarkable potential to couple wastewater treatment (WWT) to the production of value‐added compounds, in turn enhancing environmental ...

Maintenance of ATP homeostasis triggers metabolic shifts in gas-fermenting acetogens [PDF]

, 2017
Acetogens are promising cell factories for producing fuels and chemicals from waste feedstocks via gas fermentation, but quantitative characterization of carbon, energy, and redox metabolism is required to guide their rational metabolic engineering. Here,

A megatransposon drives the adaptation of Thermoanaerobacter kivui to carbon monoxide

Nature Communications
Acetogens are promising industrial biocatalysts for upgrading syngas, a gas mixture containing CO, H2 and CO2 into fuels and chemicals. However, CO severely inhibits growth of many acetogens, often requiring extensive adaptation to enable efficient CO ...

White Is a New Shade of Blue Carbon: A Case Study of a Traditional Salt Production Pond That is a Net Carbon Sink

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract To address for the first time the carbon budget of traditional salterns, we measured the diel, seasonal, and spatial variability of water‐air CO2‐eq fluxes (CH4 and CO2) and the Organic Carbon (OC) stock and burial rate in the sediment. Temperature, salinity, dissolved oxygen, pH and wind were assessed as potential environmental drivers of the

Insights into old and new acetogens: transformation barriers and genomics [PDF]

, 2019
Even though Clostridium aceticum is the first described acetogen, no reproducible protocol for genetic modification has been published in a peer-reviewed scientific article. Furthermore, C. aceticum possesses cytochromes with still unknown function.

Perspectives for Advancing Biotechnological Succinic Acid Production

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
Succinic acid is an important molecule for sustainable chemical manufacturing, but its industrial production faces high costs and sustainability challenges, which are linked to feedstocks and excessive acid/base consumption. This opinion explores production routes based on next‐generation feedstocks and low‐pH fermentations to inspire novel cost ...
