Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Heterologous Expression of the Desulfovibrio gigas [NiFe] Hydrogenase in Desulfovibrio fructosovorans MR400 [PDF]

Journal of Bacteriology, 1998
ABSTRACT The ability of Desulfovibrio fructosovorans MR400 Δ hynABC to express the heterologous cloned [NiFe] hydrogenase of Desulfovibrio gigas was investigated. The [NiFe] hydrogenase operon from D. gigas , hynABCD

Mapping the subgingival HerBiome and HisBiome over the human healthspan

Journal of Periodontology, EarlyView.
Abstract Background Understanding the intricate relationship between sex, age, and the oral microbiome is crucial for deciphering the onset and progression of numerous age‐related oral and systemic diseases. Methods Subgingival plaque was collected from 781 periodontally and systemically healthy females and 160 males spanning 0 to 80 years.

A functional description of CymA, an electron-transfer hub supporting anaerobic respiratory flexibility in Shewanella [PDF]

, 2012
CymA (tetrahaem cytochrome c) is a member of the NapC/NirT family of quinol dehydrogenases. Essential for the anaerobic respiratory flexibility of shewanellae, CymA transfers electrons from menaquinol to various dedicated systems for the reduction of ...

Periodontitis during pregnancy: The effect on the gut microbiome and intestinal inflammation

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis has been epidemiologically associated with adverse pregnancy outcomes, but causality remains difficult to establish in humans due to confounding factors. This study uses a controlled murine model to examine the effects of experimentally induced periodontitis on the composition of the gut microbiota and gastrointestinal

Induction and partial purification of bacteriophages from Desulfovibrio vulgaris (Hildenborough) and Desulfovibrio desulfuricans ATCC 13541 [PDF]

Journal of General Microbiology, 1991
Bacteriophages were induced from cultures of Desulfovibrio vulgaris NCIMB 8303 and Desulfovibrio desulfuricans ATCC 13541 by UV light. The optimum time of UV exposure was 1 min and the maximum yield of phage was obtained 9-10 h after UV treatment. The two phage preparations were compared by restriction enzyme analysis and Southern blot hybridization ...

σ54-dependent regulome in Desulfovibrio vulgaris Hildenborough [PDF]

BMC Genomics, 2015
The σ(54) subunit controls a unique class of promoters in bacteria. Such promoters, without exception, require enhancer binding proteins (EBPs) for transcription initiation. Desulfovibrio vulgaris Hildenborough, a model bacterium for sulfate reduction studies, has a high number of EBPs, more than most sequenced bacteria.

Characterization of Desulfovibrio giganteus sp. nov., a sulfate-reducing bacterium isolated from a brackish coastal lagoon [PDF]

, 1988
In the course of ecological studies in Berre Lagoon, a mediterranean brackish coastal lagoon (Marseille, France), a new slightly halophilic sulfate-reducing bacterium was isolated from anoxic sediments enriched with lactate plus sulfate, and cysteine-HCL

Phytochemicals in MASLD: A Focused Review of Gut Microbiome‐Linked Mechanisms

Phytotherapy Research, EarlyView.
ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) has emerged as a major global health burden, yet effective pharmacological options remain limited. Recent advances highlight the gut microbiome as a key modulator of liver metabolism, inflammation, and fibrosis, making it a promising therapeutic target.
