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 ...

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.

Stream Microbial Community Structured by Trace Elements, Headwater Dispersal, and Large Reservoirs in Sub-Alpine and Urban Ecosystems

Frontiers in Microbiology, 2020
Stream bacterioplankton communities, a crucial component of aquatic ecosystems and surface water quality, are shaped by environmental selection (i.e., changes in taxa abundance associated with more or less favorable abiotic conditions) and passive ...

Beyond methane consumption: exploring the potential of methanotrophic bacteria to produce secondary metabolites. [PDF]

ISME Commun
Microbial methane-consuming communities significantly impact biogeochemical processes and greenhouse gas emissions. In this study, we explored secondary metabolites produced by methane-oxidizing bacteria (MOB) and their ecological roles.

Physiological and metagenomic analyses of microbial mats involved in self-purification of mine waters contaminated with heavy metals

Frontiers in Microbiology, 2016
Two microbial mats found inside two old (gold and uranium) mines in Zloty Stok and Kowary located in SW Poland seem to form a natural barrier that traps heavy metals leaking from dewatering systems.

Decreased Snow Cover Stimulates Under-Ice Primary Producers but Impairs Methanotrophic Capacity

mSphere, 2019
Climate change scenarios anticipate decreased spring snow cover in boreal and subarctic regions. Forest lakes are abundant in these regions and substantial contributors of methane emissions.

Divergent Response of Host‐Specific Driven Gut Microbial Stability in Freshwater Gastropods to Cyanobacterial Blooms

Ecology and Evolution, Volume 15, Issue 11, November 2025.
In this study, two freshwater gastropods (Bellamya aeruginosa and Pomacea canaliculata) were used as controls to study the differences in the effects of cyanobacteria on their gut microbial communities in ponds with the absence of cyanobacterial blooms. Cyanobacterial blooms cause distinct differences in the diversity, community structure, and assembly

Methane oxidation and emission in Lake Lugano (Southern Switzerland) : a lipid biomarker and isotopic approach [PDF]

, 2015
Methane is an important greenhouse gas in Earth's atmosphere. The sources of atmospheric methane are largely biogenic, being produced under anoxic conditions by methanogenic Archaea.

Environmental Gradients and Conservation Status Determine the Structure and Carbon‐Related Metabolic Potential of the Prokaryotic Communities of Mediterranean Inland Saline Shallow Lakes

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Mediterranean inland saline shallow lakes are divided into different categories according to their salinity and conservation status, which determine the structuration of the prokaryotic communities and their carbon‐related metabolisms. ABSTRACT Mediterranean inland saline lakes may play an important role in the carbon cycle due to the metabolic ...

A metagenomic study of methanotrophic microorganisms in Coal Oil Point seep sediments

BMC Microbiology, 2011
Background Methane oxidizing prokaryotes in marine sediments are believed to function as a methane filter reducing the oceanic contribution to the global methane emission.
