Purification and characterization of a thermophilic NAD+‐dependent lactate dehydrogenase from Moorella thermoacetica

FEBS Open Bio
Oxidation of lactate under anaerobic dark fermentative conditions poses an energetic problem. The redox potential of the lactate/pyruvate couple is too electropositive to reduce the physiological electron carriers NAD(P)+ or ferredoxin.

Whole-cell biocatalysis for hydrogen storage and syngas conversion to formate using a thermophilic acetogen

Biotechnology for Biofuels, 2020
Background In times of global climate change, the conversion and capturing of inorganic CO 2 have gained increased attention because of its great potential as sustainable feedstock in the production of biofuels and biochemicals.

Exploring Ectoine Production From Methanol, Formate, and Electrochemically Produced Formate by Methyloligella halotolerans

Engineering in Life Sciences, Volume 26, Issue 1, January 2026.
ABSTRACT Microbial synthesis using renewable C1‐carbon sources like electrochemically produced formate (e‐formate) represents a promising approach for climate‐neutral chemical production. This study investigates formate utilization for ectoine biosynthesis by the halophilic methylotroph Methyloligella halotolerans.

Clumped isotopes as fingerprints of microbial methane production pathways in marine sediments

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Microbial methanogenesis in marine sediments produces significant amounts of methane from various substrates; however, identifying the active pathways in situ remains challenging. While the bulk and clumped isotopic signatures of methane from different pathways have been studied in pure cultures, these are difficult to compare with complex ...

3-Hydroxypropionate production from myo-inositol by the gut acetogen Blautia schinkii.

Environmental Microbiology
Species of the genus Blautia are not only abundant in the human gut but also contribute to human well-being. Our study demonstrates that the gut acetogen Blautia schinkii can grow on myo-inositol.

MtcB, a member of the MttB superfamily from the human gut acetogen Eubacterium limosum, is a cobalamin-dependent carnitine demethylase

Journal of Biological Chemistry, 2020
The trimethylamine methyltransferase MttB is the first described member of a superfamily comprising thousands of microbial proteins. Most members of the MttB superfamily are encoded by genes that lack the codon for pyrrolysine characteristic of ...

Telemetric Assessment and Comparison of Regional Colonic Metabolic Activity in Ambulant Healthy Individuals Using pH and Gas‐Sensing Wireless Motility Capsules

Alimentary Pharmacology &Therapeutics, Volume 63, Issue 2, Page 242-253, January 2026.
Evaluation of the novel gas‐sensing wireless motility capsules in healthy cohorts demonstrated that, in addition to quantifying regional transit times, hydrogen and carbon dioxide concentrations provide unique and reproducible insight into locoregional colonic physiology pertaining to microbial metabolic activity and fermentation.

2,3-Butanediol Metabolism in the Acetogen Acetobacterium woodii [PDF]

Applied and Environmental Microbiology, 2015
ABSTRACT The acetogenic bacterium Acetobacterium woodii is able to reduce CO 2 to acetate via the Wood-Ljungdahl pathway. Only recently we demonstrated that degradation of 1,2-propanediol by A.
