Analysis of bacterial community structure in bulk soil by in situ hybridization
In situ hybridization with rRNA-targeted, fluorescent (Cy3-labeled) oligonucleotide probes was used to analyze bacterial community structure in ethanol- or paraformaldehyde-fixed bulk soil afterExpand

A strategy for optimizing quality and quantity of DNA extracted from soil.
The efficiency of a bead beating method was studied in detail with regard to a variety of factors including beating time and speed, volume and temperature of the buffer, as well as amount and type ofExpand

Microbial Diversity and Activity along the Forefields of Two Receding Glaciers
Forefields of two receding glaciers were sampled along either a 150 or 200 m long transect at identical spatial intervals for assessment of soil microbial activity and community diversity trends. TheExpand

Influence of Microbial Growth on Hydraulic Properties of Pore Networks
From laboratory experiments it is known that bacterial biomass is able to influence the hydraulic properties of saturated porous media, an effect called bioclogging. To interpret the observations ofExpand

Bacterial, Archaeal and Fungal Succession in the Forefield of a Receding Glacier
Glacier forefield chronosequences, initially composed of barren substrate after glacier retreat, are ideal locations to study primary microbial colonization and succession in a natural environment.Expand

Activity and Diversity of Sulfate-Reducing Bacteria in a Petroleum Hydrocarbon-Contaminated Aquifer
ABSTRACT Microbial sulfate reduction is an important metabolic activity in petroleum hydrocarbon (PHC)-contaminated aquifers. We quantified carbon source-enhanced microbial SO42− reduction in aExpand

Abundances and potential activities of nitrogen cycling microbial communities along a chronosequence of a glacier forefield
Glacier forefields are ideal ecosystems to study the development of nutrient cycles as well as single turnover processes during soil development. In this study, we examined the ecology of theExpand

New Molecular Screening Tools for Analysis of Free-Living Diazotrophs in Soil
ABSTRACT Free-living nitrogen-fixing prokaryotes (diazotrophs) are ubiquitous in soil and are phylogenetically and physiologically highly diverse. Molecular methods based on universal PCR detectionExpand

Preferential Flow Paths: Biological Hot Spots in Soils
The objective of this study was to investigate whether preferential flow paths have higher microbial biomass and different microbial community structures than the rest of the soil. The organic CExpand
