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

Asia-Pacific Journal of Chemical Engineering, EarlyView.
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 ...

Engineering Acetogenic Bacteria for Efficient One-Carbon Utilization

Frontiers in Microbiology, 2022
C1 gases, including carbon dioxide (CO2) and carbon monoxide (CO), are major contributors to climate crisis. Numerous studies have been conducted to fix and recycle C1 gases in order to solve this problem.

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

The emergence and early evolution of biological carbon-fixation.

PLoS Computational Biology, 2012
The fixation of CO₂ into living matter sustains all life on Earth, and embeds the biosphere within geochemistry. The six known chemical pathways used by extant organisms for this function are recognized to have overlaps, but their evolution is ...

Anaerobic Biohydrogenation of Isoprene by Acetobacterium wieringae Strain Y

mBio, 2022
Isoprene is a ubiquitously distributed, biogenic, and climate-active organic compound. Microbial isoprene degradation in oxic environments is fairly well understood; however, studies exploring anaerobic isoprene metabolism remain scarce, with no isolates

Artificial Photosynthesis Would Unify the Electricity-Carbohydrate-Hydrogen Cycle for Sustainability [PDF]

, 2010
Sustainable development requires balanced integration of four basic human needs – air (O2/CO2), water, food, and energy. To solve key challenges, such as CO2 fixation, electricity storage, food production, transportation fuel production, water ...

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

Chemoorganoautotrophic lifestyle of the anaerobic enrichment culture N47 growing on naphthalene

Communications Biology
In almost all respiratory organisms, organic substrates are degraded via catabolic processes to the central metabolite acetyl-CoA which is then oxidized to CO2 for energy metabolism or used as a building block for anabolism.
