To What Extent Do Food Preferences Explain the Trophic Position of Heterotrophic and Mixotrophic Microbial Consumers in a Sphagnum Peatland?

Edward Mitchell, Vincent Eric Jules Jassey, Caroline Meyer

Although microorganisms are the primary drivers of biogeochemical cycles, the structure and functioning of microbial food webs are poorly studied. This is the case in Sphagnum peatlands, where microbial communities play a key role in the global carbon cycl ...

Snow cover manipulation effects on microbial community structure and soil chemistry in a mountain bog

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

Alterations in snow cover driven by climate change may impact ecosystem functioning, including biogeochemistry and soil (microbial) processes. We elucidated the effects of snow cover manipulation (SCM) on above-and belowground processes in a temperate peat ...

Above- and belowground linkages in Sphagnum peatland: climate warming affects plant-microbial interactions

Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey

Peatlands contain approximately one third of all soil organic carbon (SOC). Warming can alter above- and belowground linkages that regulate soil organic carbon dynamics and C-balance in peatlands. Here we examine the multiyear impact of in situ experimenta ...

Seasonal patterns of testate amoeba diversity, community structure and species-environment relationships in four Sphagnum-dominated peatlands along a 1300 m altitudinal gradient in Switzerland

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Mariusz Lamentowicz

Altitudinal gradients are useful to study the potential effects of climate change on ecosystems. Historically, studies on elevation gradients have primarily focused on macro-organisms and ecosystem processes, while microorganisms have been mostly ignored d ...

Biophysical controls on cluster dynamics and architectural differentiation of microbial biofilms in contrasting flow environments

Andrea Rinaldo, Tom Ian Battin, Enrico Bertuzzo, Lorenzo Mari, Samir Suweis

Ecology, with a traditional focus on plants and animals, seeks to understand the mechanisms underlying structure and dynamics of communities. In microbial ecology, the focus is changing from planktonic communities to attached biofilms that dominate microbi ...

Microbial diversity differences within aerobic granular sludge and activated sludge flocs

In this study, we investigated during 400 days the microbial community variations as observed from 16S DNA gene DGGE banding patterns from an aerobic granular sludge pilot plant as well as the from a full-scale activated sludge treatment plant in Epe, the ...

The biofilm granulation mechanisms depend on the predominant populations involved

Christof Holliger, David Gregory Weissbrodt, Samuel Lochmatter

The novel aerobic granular sludge technology is attractive for intensified biological nutrient removal from wastewater. This process is based on self-granulated flocs forming fast-settling mobile biofilms with a gel-like consistence, called “granules”. Mec ...

Implications of in situ calcification for photosynthesis in a similar to 3.3 Ga-old microbial biofilm from the Barberton greenstone belt, South Africa

Anders Meibom, François Robert

Timing the appearance of photosynthetic microorganisms is crucial to understanding the evolution of life on Earth. The ability of the biosphere to use sunlight as a source of energy (photoautotrophy) would have been essential for increasing biomass and for ...

Modeling the effectiveness of U(VI) biomineralization in dual porosity porous media

David Andrew Barry

Recent attention has focused on the in situ immobilization of uranium by stimulation of dissimilatory metal-reducing bacteria (DMRB). The objective of this work was to investigate the effectiveness of this approach in heterogeneous and structured porous me ...

Dynamics of Microbial Community Structure of and Enhanced Biological Phosphorus Removal by Aerobic Granules Cultivated on Propionate or Acetate

Christof Holliger, Graciela Gonzalez Gil

Aerobic granules are dense microbial aggregates with the potential to replace floccular sludge for the treatment of wastewaters. In bubble-column sequencing batch reactors, distinct microbial populations dominated propionate-and acetate-cultivated aerobic ...
