Microenvironments and microbial community structure in sediments
Environmental Microbiology, 2002Summary The aim of this study was to explore the potential of a combined chemical and microbiological approach as part of a study of organic carbon oxidation processes in sediments. An assessment of microbiological diversity using molecular techniques was carried out in combination with high resolution chemical ...

Silver removal and microbial community structure in microbial fuel cells
Journal of Chemical Technology & Biotechnology, 2022AbstractBackgroundSilver (Ag) removal, electric current generation and the microbial community responsible were investigated in two replicate dual‐chamber microbial fuel cells (MFCs). The MFCs were inoculated with activated sludge and operated for electricity generation over 90 days.ResultsSilver was efficiently removed from synthetic wastewater at the

Microbial community structure and its functional implications
Nature, 2009Marine microbial communities are engines of globally important processes, such as the marine carbon, nitrogen and sulphur cycles. Recent data on the structures of these communities show that they adhere to universal biological rules. Co-occurrence patterns can help define species identities, and systems-biology tools are revealing networks of ...

Structure–Function Relationships of Microbial Communities
2014Microbial community structure is the result of environmental conditions that vary significantly and frequently. In laboratory conditions, associations from two microorganisms to complex microbial communities are used to mimic real ecosystems and their functions.

Drivers of microbial community structure in forest soils
Applied Microbiology and Biotechnology, 2018Forests are essential biomes for global biogeochemical cycles, and belowground microorganisms have a key role in providing relevant ecosystem services. To predict the effects of environmental changes on these ecosystem services requires a comprehensive understanding of how biotic and abiotic factors drive the composition of microbial communities in ...

Soil and plant effects on microbial community structure
Canadian Journal of Microbiology, 2002We investigated the effects of two different plant species (corn and soybean) and three different soil types on microbial community structure in the rhizosphere. Our working hypothesis was that the rhizosphere effect would be strongest on fast-growing aerobic heterotrophs, while there would be little or no rhizosphere effect on oligotrophic and other ...

Oxygen and the Spatial Structure of Microbial Communities
Biological Reviews, 2008AbstractOxygen has two faces. On one side it is the terminal electron acceptor of aerobic respiration – the most efficient engine of energy metabolism. On the other hand, oxygen is toxic because the reduction of molecular O2creates reactive oxygen species such as the superoxide anion, peroxide, and the hydroxyl radical.

Microbial community structure in polluted Baltic Sea sediments
Environmental Microbiology, 2005Summary Nearly half the seabed of the Baltic Proper is incapable of supporting life of higher organisms as a consequence of oxygen depletion resulting from eutrophication. However, these areas are actually teeming with microbial life.

Microbial community structure and trichloroethylene degradation in groundwater
Canadian Journal of Microbiology, 2005Trichloroethylene (TCE) is a prevalent contaminant of groundwater that can be cometabolically degraded by indigenous microbes. Groundwater contaminated with TCE from a US Department of Energy site in Ohio was used to characterize the site-specific impact of phenol on the indigenous bacterial community for use as a possible remedial strategy ...
