Trace elements induce predominance among methanogenic activity in anaerobic digestion

open access: yesFrontiers 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 ...

Site directed mutagenesis of L-pyrrolysine in dimethylamine methyltransferase [PDF]

open access: yes, 2009
Methanosarcina barkeri is an archaeon and is able to use methylamines as growth substrates for methanogenesis. The methylamine methyltransferases that are involved in initiating methanogenesis from the methylamines have an in-frame amber codon (UAG) that

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

open access: yesFood 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.

Ultrafine Metallic Particles as Inducers of Digestive Processes in Rumen: Dry Matter Digestibility of Feed and Enzymatic Activity

open access: yesScientifica, Volume 2025, Issue 1, 2025.
The ban on the use of antibiotics in animal husbandry encourages an active search for highly effective alternatives with additional properties, one of which is ultrafine particles (UFP) of metallic nature. The objective of the presented work was to conduct a comprehensive analysis of newly synthesized UFP Co3O4 and Mn2O3, including determination of ...

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

open access: yesBMC 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 ...

Reductive dechlorination in the energy metabolism of anaerobic bacteria [PDF]

open access: yes, 2017
Within the last few decades, several anaerobic bacteria have been isolated which are able to reductively dechlorinate chlorinated aliphatic and aromatic compounds at catabolic rates.

Unravelling the one-carbon metabolism of the acetogen Sporomusa strain An4 by genome and proteome analysis [PDF]

open access: yes, 2016
The Sporomusa genus comprises anaerobic spore-forming acetogenic bacteria that stain Gram-negative. Sporomusa species typically grow with one-carbon substrates and N-methylated compounds.

Redox, haem and CO in enzymatic catalysis and regulation [PDF]

open access: yes, 2012
The present paper describes general principles of redox catalysis and redox regulation in two diverse systems. The first is microbial metabolism of CO by the Wood–Ljungdahl pathway, which involves the conversion of CO or H2/CO2 into acetyl-CoA, which ...

Divergent roles of CprK paralogues from Desulfitobacterium hafniense in activating gene expression [PDF]

open access: yes, 2008
Gene duplication and horizontal gene transfer play an important role in the evolution of prokaryotic genomes. We have investigated the role of three CprK paralogues from the cAMP receptor protein-fumarate and nitrate reduction regulator (CRP-FNR) family ...

Syntheses and characterization of vitamin B12-Pt(II) conjugates and their adenosylation in an enzymatic assay [PDF]

open access: yes, 2018
Aiming at the use of vitamin B12 as a drug delivery carrier for cytotoxic agents, we have reacted vitaminB12 with trans-[PtCl(NH3)2(H2O)]+, [PtCl3(NH3)]− and [PtCl4]2−. These Pt(II) precursors coordinated directly to the Co(III)-bound cyanide, giving the
