Methanol and Carbon Monoxide Metabolism of the Thermophile Moorella caeni

Environmental Microbiology, Volume 27, Issue 4, April 2025.
An omics approach was used to elucidate the C1 metabolism of Moorella caeni DSM 21394 T, which exhibits acetogenic metabolism on methanol and hydrogenogenic metabolism on CO. Our results suggest that respiratory Complex I serves as the primary respiratory enzyme in methanol‐grown cells.

Novel molecular markers for the detection of methanogens and phylogenetic analyses of methanogenic communities

Frontiers in Microbiology, 2015
Methanogenic Archaea produce approximately one billion tons of methane annually, but their biology remains largely unknown. This is partially due to the large phylogenetic and phenotypic diversity of this group of organisms, which inhabit various anoxic ...

Metagenomic Exploration Uncovers Several Novel ‘Candidatus’ Species Involved in Acetate Metabolism in High‐Ammonia Thermophilic Biogas Processes

Microbial Biotechnology, Volume 18, Issue 3, March 2025.
Metagenomic analysis of three thermophilic species was performed to identify key species for stable biogas production at high free ammonia levels (> 0.7 g/L). Potential acetogens and syntrophic acetate‐oxidising bacteria (SAOB) were recovered by looking for genes of the Wood–Ljungdahl pathway and glycine synthase reductase pathway.

Control of Metal-Catalyzed Reactions by Organic Ligands: From Corrinoid and Porphinoid Metal Complexes to Tailor-Made Catalysts for Asymmetric Synthesis

CHIMIA, 2006
Corrinoid and porphinoid metal complexes playa fundamental role in nature as catalysts for a variety of biochemical transformations. The properties of the metal ion in these complexes are strongly influenced by the macrocyclic ligand.

Comparative metagenomics of three Dehalococcoides-containing enrichment cultures: the role of the non-dechlorinating community

BMC Genomics, 2012
Background The Dehalococcoides are strictly anaerobic bacteria that gain metabolic energy via the oxidation of H2 coupled to the reduction of halogenated organic compounds. Dehalococcoides spp.

Sister Dehalobacter Genomes Reveal Specialization in Organohalide Respiration and Recent Strain Differentiation Likely Driven by Chlorinated Substrates

Frontiers in Microbiology, 2016
The genomes of two closely related Dehalobacter strains (strain CF and strain DCA) were assembled from the metagenome of an anaerobic enrichment culture that reductively dechlorinates chloroform (CF), 1,1,1-trichloroethane (1,1,1-TCA) and 1,1 ...

Vitamin B12: prevention of human beings from lethal diseases and its food application

Journal of the Science of Food and Agriculture, Volume 105, Issue 1, Page 10-18, 15 January 2025.
Abstract Vitamin B12, a water‐soluble essential micronutrient, plays a pivotal role in numerous physiological processes in the human body. This review meticulously examines the structural complexity and the diverse mechanisms through which vitamin B12 exerts its preventive effects against a spectrum of health conditions, including pernicious anaemia ...

Trace elements induce predominance among methanogenic activity in anaerobic digestion

Frontiers in Microbiology, 2016
Trace elements play an essential role in all organisms due to their functions in enzyme complexes. In anaerobic digesters, control and supplementation of trace elements lead to stable and more efficient methane production processes while trace element ...

Unveiling the potentials and action mechanisms of Citri reticulatae Pericarpium as an anti‐inflammatory food

Food Frontiers, Volume 6, Issue 1, Page 163-184, January 2025.
The review summarized advances in utilizing CRP for the prevention and treatment of inflammation under various pathological conditions. The underlying mechanism has focused on polymethoxyflavones (PMFs) present in CRP and its interaction with gut microbiota. Abstract Modern lifestyle has led human body under a frequent exposure of chronic inflammation.

Genomic determinants of organohalide-respiration in Geobacter lovleyi, an unusual member of the Geobacteraceae

BMC Genomics, 2012
Background Geobacter lovleyi is a unique member of the Geobacteraceae because strains of this species share the ability to couple tetrachloroethene (PCE) reductive dechlorination to cis-1,2-dichloroethene (cis-DCE) with energy conservation and growth (i ...
