Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

Advanced Science, Volume 13, Issue 17, 23 March 2026.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

CO2 Electroreduction to Multicarbon Products in Acidic Electrolyte via Structural Reconstruction of a Molybdenum Porphyrin Dimer

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
A novel oxo‐bridged molybdenum porphyrin dimer electrocatalyst undergoes potential‐driven structural reconstruction in acidic electrolyte, forming MoMo bonded active sites. This dynamic transformation enables selective electrochemical CO2 reduction to multicarbon products: methanol with 74% Faradaic efficiency at −1.0 V versus RHE, and ethanol with 45%

Isolation of an Obligate Mixotrophic Methanogen That Represents the Major Population in Thermophilic Fixed-Bed Anaerobic Digesters

Microorganisms, 2020
Methanothermobacter Met2 is a metagenome-assembled genome (MAG) that encodes a putative mixotrophic methanogen constituting the major populations in thermophilic fixed-bed anaerobic digesters.

Great metalloclusters in enzymology [PDF]

, 2002
Metallocluster-containing enzymes catalyze some of the most basic redox transformations in the biosphere. The reactions catalyzed by these enzymes typically involve small molecules such as N2, CO, and H2 that are used to generate both chemical building ...

Case‐Based Immunology: B Cells and Systemic Sclerosis Interstitial Lung Disease

Arthritis &Rheumatology, Volume 78, Issue 3, Page 566-581, March 2026.
Interstitial lung disease (ILD) is an important complication of systemic sclerosis (SSc), with high mortality and morbidity. Recent clinical studies in SSc‐ILD have led to US Food and Drug Administration–approved therapies in SSc‐ILD. Importantly, evidence from these studies has been extrapolated to guide management of ILDs of other systemic autoimmune

Paramagnetic centers of carbon monoxide dehydrogenase from aceticlastic Methanosarcina barkeri

Journal of Biological Chemistry, 1989
Carbon monoxide dehydrogenase from Methanosarcina barkeri, purified to 95% homogeneity, contains 30 Fe, 2 Ni, 1 Zn, and 1 Cu (per alpha 2 beta 2 enzyme). Core extrusion experiments indicate 6 [4Fe-4S] clusters/tetramer, and electron paramagnetic resonance (epr) spectroscopy detects at least one of these clusters, in the reduced form, with apparent g ...

Comparative biochemistry of CO2 fixation and the evolution of autotrophy [PDF]

, 2010
Carbon dioxide fixation is a polyphyletic trait that has evolved in widely separated prokaryotic branches. The three principal CO2-assimilation pathways are (i) the reductive pentose-phosphate cycle, i. e.

Comparative genomics in acid mine drainage biofilm communities reveals metabolic and structural differentiation of co-occurring archaea [PDF]

, 2016
Background Metal sulfide mineral dissolution during bioleaching and acid mine drainage (AMD) formation creates an environment that is inhospitable to most life. Despite dominance by a small number of bacteria, AMD microbial biofilm communities contain a

Systemic engineering and global regulation enabling high-level bilirubin biosynthesis

Nature Communications
Bilirubin biosynthesis has long been constrained by low yields and poorly understood bottlenecks. Here, we report a fully in vitro pathway that converts heme to bilirubin with the titer of 1.7 g/L and 95.8%.
