Renewable Hydrogen Production and Storage Via Enzymatic Interconversion of CO2 and Formate with Electrochemical Cofactor Regeneration

ChemSusChem, Volume 16, Issue 17, September 8, 2023., 2023
Formic acid (FA) is a promising hydrogen carrier. Formate dehydrogenase catalyzes the CO2 reduction to FA with need of a cofactor that can be regenerated efficiently in a bioelectrochemical system. Bacterial enzyme complexes are capable of dehydrogenating FA to produce hydrogen.

Utilization of Cathodic Hydrogen by Desulfovibrio vulgaris (Hildenborough) [PDF]

Microbiology, 1986
Summary: Desulfovibrio vulgaris (Hildenborough) can grow on acetate plus CO2 as carbon source with H2 as the sole source of energy. The capability of sulphate reducers to oxidize H2 has been proposed as a major factor in the anaerobic corrosion of metals. Utilization by D.

Comproportionation of CO2 and Cellulose to Formate Using a Floating Semiconductor‐Enzyme Photoreforming Catalyst

Angewandte Chemie, Volume 135, Issue 20, May 8, 2023., 2023
Simultaneous formate formation from CO2 reduction and cellulose oxidation is enabled by a biohybrid photocatalyst with formate dehydrogenase immobilized on titanium dioxide. The semi‐artificial photocatalytic system can be further immobilized onto floating hollow glass microspheres allowing vertical solar light illumination with optimal light exposure ...

Purification and characterization of the formate dehydrogenase fromDesulfovibrio vulgarisHildenborough [PDF]

FEMS Microbiology Letters, 1995
Formate dehydrogenase from Desulfovibrio vulgaris Hildenborough, a sulfate-reducing bacterium, has been isolated and characterized. The enzyme is composed of three subunits. A high molecular mass subunit (83,500 Da) is proposed to contain a molybdenum cofactor, a 27,000 Da subunit is found to be similar to the Fe-S subunit of the formate dehydrogenase ...

Expanded Diversity of Microbial Groups Capable of Anaerobic Pyrite Reduction and Assimilation of Dissolution Products. [PDF]

Environ Microbiol
Expanded diversity of microbial groups capable of anaerobic pyrite reduction. Devon Payne and Eric Boyd. Different microbial guilds were tested for their ability to reductively dissolve pyrite and mobilize iron and sulfur to support growth. Metabolic guilds capable of pyrite reduction were determined (top) and mechanisms of extracellular electron ...

Tungsten and molybdenum regulation of formate dehydrogenase expression in Desulfovibrio vulgaris Hildenborough. [PDF]

J Bacteriol, 2011
ABSTRACT Formate is an important energy substrate for sulfate-reducing bacteria in natural environments, and both molybdenum- and tungsten-containing formate dehydrogenases have been reported in these organisms. In this work, we studied the effect of both metals on the levels of the three formate dehydrogenases encoded in the ...

Probing the Structure of [NiFeSe] Hydrogenase with QM/MM Computations

Applied Sciences, 2020
The geometry and vibrational behavior of selenocysteine [NiFeSe] hydrogenase isolated from Desulfovibrio vulgaris Hildenborough have been investigated using a hybrid quantum mechanical (QM)/ molecular mechanical (MM) approach. Structural models have been
