Genomic Reconstruction of an Uncultured Hydrothermal Vent Gammaproteobacterial Methanotroph (Family Methylothermaceae) Indicates Multiple Adaptations to Oxygen Limitation [PDF]

, 2015
Hydrothermal vents are an important contributor to marine biogeochemistry, producing large volumes of reduced fluids, gasses, and metals and housing unique, productive microbial and animal communities fueled by chemosynthesis.

Leveraging core enzyme structures for microbiota targeted functional regulation: Urease as an example. [PDF]

Imeta
We present an innovative methodology that integrates core enzyme identification, protein structural characterization, regulator virtual screening, and functional validation to achieve precise microbiome functional regulation. As a proof of concept, we focused on the regulation of urea decomposition by the rumen microbiota in ruminants. This methodology

Microplastic polymer properties as deterministic factors driving terrestrial plastisphere microbiome assembly and succession in the field

Environmental Microbiology, Volume 25, Issue 12, Page 2681-2697, December 2023., 2023
Abstract Environmental microplastic (MP) is ubiquitous in aquatic and terrestrial ecosystems providing artificial habitats for microbes. Mechanisms of MP colonization, MP polymer impacts, and effects on soil microbiomes are largely unknown in terrestrial systems.

Biogeography of microbial communities in high‐latitude ecosystems: Contrasting drivers for methanogens, methanotrophs and global prokaryotes

Environmental Microbiology, Volume 25, Issue 12, Page 3364-3386, December 2023., 2023
Methane cycle is crucial in high‐latitude ecosystems as global warming makes permafrost organic carbon increasingly available. An extensive dataset of methane‐linked microbial communities, physicochemical, climatic and geographic variables was investigated under a standardized methodology.

Vertical niche occupation and potential metabolic interplay of microbial consortia in a deeply stratified meromictic model lake

Limnology and Oceanography, Volume 68, Issue 11, Page 2492-2511, November 2023., 2023
Abstract The microbial ecology of meromictic lakes assessed with “omics” is still poorly studied compared to other aquatic systems. Here, a combination of metagenomics, high resolution sampling and detailed physical–chemical data gathering allowed to study the planktonic prokaryotic assemblages and metabolic capabilities in the crenogenic meromictic ...

Planktonic and sediment-associated aerobic methanotrophs in two seep systems along the North American margin [PDF]

, 2008
Methane vents are of significant geochemical and ecological importance. Notable progress has been made towards understanding anaerobic methane oxidation in marine sediments, however, the diversity and distribution of aerobic methanotrophs in the water ...

Seasonal shifts in community composition and proteome expression in a sulphur‐cycling cyanobacterial mat

Environmental Microbiology, Volume 25, Issue 11, Page 2516-2533, November 2023., 2023
We studied temporal shifts in irradiance, water chemistry, and community structure and function of microbial mats in Middle Island Sinkhole (MIS), an O2‐poor benthic sinkhole in Lake Huron, Michigan where anoxic and sulphate‐rich groundwater provides habitat for cyanobacteria that conduct both oxygenic and anoxygenic photosynthesis.

Niche differentiation in nitrogen metabolism among methanotrophs within an operational taxonomic unit [PDF]

, 2014
Background: The currently accepted thesis on nitrogenous fertilizer additions on methane oxidation activity assumes niche partitioning among methanotrophic species, with activity responses to changes in nitrogen content being dependent on the in situ ...

A comparative in situ decomposition study using still born piglets and leaf litter from a deciduous forest [PDF]

, 2017
A cadaver and dead plant organic matter, or litter, are rich energy sources that undergo a complex decomposition process, which impact the surrounding environmental microbiota.
