A role for nickel-iron cofactors in biological carbon monoxide and carbon dioxide utilization [PDF]

, 2010
Ni–Fe containing enzymes are involved in the biological utilization of carbon monoxide, carbon dioxide, and hydrogen. Interest in these enzymes has increased in recent years due to hydrogen fuel initiatives and concerns over development of new methods ...

Enrichment of syngas-converting communities from a multi-orifice baffled bioreactor [PDF]

, 2017
The substitution of natural gas by renewable biomethane is an interesting option to reduce global carbon footprint. Syngas fermentation has potential in this context, as a diverse range of low-biodegradable materials that can be used.

Reductive activation of methanol: 5-Hydroxybenzimidazolylcobamide methyltransferase of Methanosarcina barkeri

Biochemical and Biophysical Research Communications, 1984
Methanol: 5-hydroxybenzimidazolylcobamide methyltransferase (MT1) from Methanosarcina barkeri, which is one of the enzymes responsible for the transmethylation from methanol to coenzyme M, was found to be activated in the presence of hydrogenase and ferredoxin. This activation was shown to involve a reduction of the bound corrinoid to the Co (I) level,

Carbon-dependent control of electron transfer and central carbon pathway genes for methane biosynthesis in the Archaean, Methanosarcina acetivorans strain C2A

BMC Microbiology, 2010
Background The archaeon, Methanosarcina acetivorans strain C2A forms methane, a potent greenhouse gas, from a variety of one-carbon substrates and acetate. Whereas the biochemical pathways leading to methane formation are well understood, little is known

Activation mechanism of methanol:5-hydroxybenzimidazolylcobamide methyltransferase from Methanosarcina barkeri.

The Journal of biological chemistry, 1996
Methanol:5-hydroxybenzimidazolylcobamide methyltransferase (MT1) is the first of two enzymes involved in the transmethylation reaction from methanol to 2-mercaptoethanesulfonic acid in Methanosarcina barkeri. MT1 only binds the methyl group of methanol when the cobalt atom of its corrinoid prosthetic groups is present in the highly reduced Co(I) state.

Comparative Metagenomic Analysis of Electrogenic Microbial Communities in Differentially Inoculated Swine Wastewater-Fed Microbial Fuel Cells

Scientifica, 2017
Bioelectrochemical systems such as microbial fuel cells (MFCs) are promising new technologies for efficient removal of organic compounds from industrial wastewaters, including that generated from swine farming. We inoculated two pairs of laboratory-scale

Expanding the Diet for DIET: Electron Donors Supporting Direct Interspecies Electron Transfer (DIET) in Defined Co-Cultures

Frontiers in Microbiology, 2016
Direct interspecies electron transfer (DIET) has been recognized as an alternative to interspecies H2 transfer as a mechanism for syntrophic growth, but previous studies on DIET with defined co-cultures have only documented DIET with ethanol as the ...

Isolation of Extracellular Cobalt-free Corrinoid fromMethanosarcina barkeri

Agricultural and Biological Chemistry, 1989
Cobalt-free corrinoids (CFCs) were isolated from Methanosarcina barkeri Fusaro cells growing on a methanol minimum medium. The methanogen cells excreted a trace of CFCs (9.1 μg/I) into the culture medium when cobalt-deficient methanol medium was used.
