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 ...

Adaptation of the acetogen Clostridium thermoautotrophicum to minimal medium [PDF]

Journal of Bacteriology, 1986
Clostridium thermoautotrophicum was adapted to minimal medium and cultivated at the expense of glucose, methanol, or H2-CO2. No supplemental amino acids were required for growth of the adapted strain, and nicotinic acid was the sole essential vitamin.

No acetogen is equal: Strongly different H ₂ thresholds reflect diverse bioenergetics in acetogenic bacteria

Environmental Microbiology, 2023
Abstract Acetogens share the capacity to convert H 2 and CO 2 into acetate for energy conservation (ATP synthesis). This reaction is attractive for applications, such as gas fermentation and microbial electrosynthesis. Different H

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).

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 ...

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

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 ...

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 ...

Production of the biocommodities butanol and acetone from methanol with fluorescent FAST-tagged proteins using metabolically engineered strains of Eubacterium limosum

Biotechnology for Biofuels, 2021
Background The interest in using methanol as a substrate to cultivate acetogens increased in recent years since it can be sustainably produced from syngas and has the additional benefit of reducing greenhouse gas emissions.

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...
