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 ...

In situ differences in nitrogen cycling related to presence of submerged aquatic vegetation in a Gulf of Mexico estuary

Ecosphere, Volume 13, Issue 12, December 2022., 2022
Abstract Estuaries provide a suite of ecosystem services to people but are also under heavy stress from human development including excess nutrient loading and alterations in benthic habitat that affect nutrient cycling. Here we examine the interaction of two important and common ecosystem management priorities in estuaries: limiting eutrophication and

Rhizosphere Microbiome as an Underexplored Resource for Agroecosystem Sustainability: Insights From the Carrot Root Zone. [PDF]

Environ Microbiol Rep
The diagram represents the generalised pathways for the ecological activities mediated by the rhizosphere microbiome within crop‐soil interactions, based on existing literature. The conceptual pathways are adapted for the carrot root‐zone context described in this review. These activities include the transformation of organic matter, promotion of plant

Planktonic microbial communities from microbialite‐bearing lakes sampled along a salinity‐alkalinity gradient

Limnology and Oceanography, Volume 67, Issue 12, Page 2718-2733, December 2022., 2022
Abstract Continental freshwater systems are particularly vulnerable to environmental variation. Climate change‐induced desertification and the anthropogenic exploitation of hydric resources result in the progressive evaporation and salinization of inland water bodies in many areas of the globe.

Physiology of purple sulfur bacteria forming macroscopic aggregates in Great Sippewissett Salt Marsh, Massachusetts [PDF]

, 1993
Purple bacterial aggregates found in tidal pools of Great Sippewissett Salt Marsh (Falmouth, Cape Cod, MA) were investigated in order to elucidate the ecological significance of cell aggregation. Purple sulfur bacteria were the dominant microorganisms in

Freshwater mussels and host fish gut microbe community composition shifts after agricultural contaminant exposure

Journal of Applied Microbiology, Volume 133, Issue 6, Page 3645-3658, December 2022., 2022
Abstract Aims We examined the effects of a mixture of contaminants found in agricultural watersheds on the gut microbiota and physiology of both the freshwater mussel Lampsilis cardium, and L. cardium host fish Micropterus salmoides. Methods and results Lampsilis cardium and M. salmoides were exposed to three concentrations of agricultural contaminants

Introduction of exotic species Sonneratia apetala alters diazotrophic community and stimulates nitrogen fixation in mangrove sediments

Ecological Indicators, 2022
Mangrove restoration by exotic mangrove species Sonneratia apetala has been practiced as a strategy to reconstruct mangrove wetlands. Diazotrophs in mangrove sediment are nitrogen suppliers for mangrove ecosystems.

Prokaryotic Diversity and Dynamics during Dinoflagellate Bloom Decays in Coastal Tunisian Waters

Diversity, 2023
(1) Background: Harmful algal blooms (HABs) can negatively impact marine ecosystems, but few studies have evaluated the microbial diversity associated with HABs and its potential role in the fates of these proliferations.

Electrochemical Characterization of Marinobacter atlanticus Strain CP1 Suggests a Role for Trace Minerals in Electrogenic Activity

Frontiers in Energy Research, 2019
The marine heterotroph, Marinobacter atlanticus strain CP1, was recently isolated from the electroautotrophic Biocathode MCL community, named for the three most abundant members: Marinobacter, an uncharacterized member of the Chromatiaceae, and Labrenzia.
