The soil microbiome at the Gi-FACE experiment responds to a moisture gradient but not to CO2 enrichment [PDF]

open access: yes, 2016
The soil bacterial community at the Giessen free-air CO2 enrichment (Gi-FACE) experiment was analysed by tag-sequencing of the 16S rRNA gene. No substantial effects of CO2 levels on bacterial community composition were detected.

Microbial biogeography of arctic streams: exploring influences of lithology and habitat

open access: yesFrontiers in Microbiology, 2012
Terminal restriction fragment length polymorphism and 16S rRNA gene sequencing were used to explore the community composition of bacterial communities in biofilms on sediments (epipssamon) and rocks (epilithon) in stream reaches that drain watersheds ...

Repeated pulse feeding induces functional stability in anaerobic digestion [PDF]

open access: yes, 2013
Anaerobic digestion is an environmental key technology in the future bio-based economy. To achieve functional stability, a minimal microbial community diversity is required. This microbial community should also have a certain “elasticity”, i.e.

The effects of clays on bacterial community composition during arthropod decay. [PDF]

open access: yesSwiss J Palaeontol
Abstract Fossilization, or the transition of an organism from the biosphere to the geosphere, is a complex mechanism involving numerous biological and geological variables. Bacteria are one of the most significant biotic players to decompose organic matter in natural environments, early on during fossilization ...

Analysis of Bacterial Community Composition by Oligonucleotide Fingerprinting of rRNA Genes [PDF]

open access: yesApplied and Environmental Microbiology, 2002
ABSTRACT One of the first steps in characterizing an ecosystem is to describe the organisms inhabiting it. For microbial studies, experimental limitations have hindered the ability to depict diverse communities. Here we describe oligonucleotide fingerprinting of rRNA genes (OFRG), a method that permits identification of arrayed ...

Composition of the bacterial community in the gastrointestinal tract of Kunming mice

open access: yesElectronic Journal of Biotechnology, 2020
Background: The intestinal bacterial community has an important role in maintaining human health. Dysbiosis is a key inducer of many chronic diseases including obesity and diabetes.

How Microbial Food Web Interactions Shape the Arctic Ocean Bacterial Community Revealed by Size Fractionation Experiments

open access: yesMicroorganisms, 2021
In the Arctic, seasonal changes are substantial, and as a result, the marine bacterial community composition and functions differ greatly between the dark winter and light-intensive summer. While light availability is, overall, the external driver of the

Phylogenetic signals of salinity and season in bacterial community composition across the salinity gradient of the Baltic Sea

open access: yesFrontiers in Microbiology, 2016
Understanding the key processes that control bacterial community composition has enabled predictions of bacterial distribution and function within ecosystems.

Species dynamics in natural bacterial communities over multiple rounds of propagation

open access: yesEvolutionary Applications, 2022
Our experimental work illustrates how microbial ecosystems can be shaped by selective pressures over long‐term ecological time scales. Natural microbial ecosystems generally consist of various co‐existing species, where community composition describes ...

Straw Return and Nitrogen Fertilization to Maize Regulate Soil Properties, Microbial Community, and Enzyme Activities Under a Dual Cropping System

open access: yesFrontiers in Microbiology, 2022
Soil sustainability is based on soil microbial communities’ abundance and composition. Straw returning (SR) and nitrogen (N) fertilization influence soil fertility, enzyme activities, and the soil microbial community and structure.
