Thermodynamic modelling of synthetic communities predicts minimum free energy requirements for sulfate reduction and methanogenesis [PDF]

, 2020
Microbial communities are complex dynamical systems harbouring many species interacting together to implement higher-level functions. Among these higher-level functions, conversion of organic matter into simpler building blocks by microbial communities ...

Elevated CO2 and Warming Altered Grassland Microbial Communities in Soil Top-Layers. [PDF]

, 2018
As two central issues of global climate change, the continuous increase of both atmospheric CO2 concentrations and global temperature has profound effects on various terrestrial ecosystems.

Inclusion of seasonal variation in river system microbial communities and phototroph activity increases environmental relevance of laboratory chemical persistence tests [PDF]

, 2020
Regulatory tests assess crop protection product environmental fate and toxicity before approval for commercial use. Although globally applied laboratory tests can assess biodegradation, they lack environmental complexity.

Activated Sludge Microbial Community Assembly: The Role of Influent Microbial Community Immigration

Applied and Environmental Microbiology, 2023
AbstractWastewater treatment plants (WWTPs) are host to diverse microbial communities and receive a constant influx of microbes from influent wastewater, however the impact of immigrants on the structure and activities of the activated sludge (AS) microbial community remains unclear.

Growth and Break-Up of Methanogenic Granules Suggests Mechanisms for Biofilm and Community Development

Frontiers in Microbiology, 2020
Methanogenic sludge granules are densely packed, small, spherical biofilms found in anaerobic digesters used to treat industrial wastewaters, where they underpin efficient organic waste conversion and biogas production.

Influence of coral and algal exudates on microbially mediated reef metabolism. [PDF]

, 2013
Benthic primary producers in tropical reef ecosystems can alter biogeochemical cycling and microbial processes in the surrounding seawater. In order to quantify these influences, we measured rates of photosynthesis, respiration, and dissolved organic ...

Microbial differences between dental plaque and historic dental calculus are related to oral biofilm maturation stage [PDF]

, 2019
Dental calculus, calcified oral plaque biofilm, contains microbial and host biomolecules that can be used to study historic microbiome communities and host responses.

Comparative Metagenomics of Microbial Communities [PDF]

Science, 2005
The species complexity of microbial communities and challenges in culturing representative isolates make it difficult to obtain assembled genomes. Here we characterize and compare the metabolic capabilities of terrestrial and marine microbial communities using largely unassembled sequence data obtained by shotgun sequencing DNA isolated from the ...

Genomic and in Situ Analyses Reveal the Micropruina spp. as Abundant Fermentative Glycogen Accumulating Organisms in Enhanced Biological Phosphorus Removal Systems

Frontiers in Microbiology, 2018
Enhanced biological phosphorus removal (EBPR) involves the cycling of biomass through carbon-rich (feast) and carbon-deficient (famine) conditions, promoting the activity of polyphosphate accumulating organisms (PAOs).

Direct Identification of Functional Amyloid Proteins by Label-Free Quantitative Mass Spectrometry

Biomolecules, 2017
Functional amyloids are important structural and functional components of many biofilms, yet our knowledge of these fascinating polymers is limited to a few examples for which the native amyloids have been isolated in pure form.
