Microorganisms play pivotal roles within aquatic ecosystems, affecting their structure, functioning and services. However, little is known about the effects of water stratification mixing on microbial community dynamics in subtropical reservoirs. In this study, we explored vertical seasonal patterns diversity Dongzhen Reservoir (southeast China). Quantitative PCR, quantitative RT-PCR 454 pyrosequencing were used for an in-depth characterization bacterial across time (every three months one...
Summary Bacterial communities associated with a variety of benthic detritus types were studied in three streams the context chemical characteristics sediment material and stream water. A cell purification assay was developed for quantitative microscopic evaluation bacterial community structure samples by fluorescence situ hybridization (FISH). The efficiency FISH fluorescently monolabelled probes compared signal amplification catalysed reporter deposition (CARD‐FISH). In poor organic carbon...
Playing your part: Conductive magnetite nanoparticles accelerate the microbial reductive dechlorination of trichloroethene (TCE), an ubiquitous and toxic subsurface contaminant. The stimulatory effect most likely results from promoting establishment interspecies electron transfer (IET) processes between non-dechlorinating dechlorinating microorganisms.
Abstract Heterotrophic bacteria play a key role in the degradation of organic matter and carbon cycling river sediments. These bacterial communities are directly influenced by environmental variables that differ spatially temporally rivers. Here, we studied longitudinal patterns sediment community composition dissolved utilization under base flow drought conditions Mediterranean river. Our results indicated microbial were affected quality origin along continuum. In headwaters potential...
Within human-impacted areas, high levels of inorganic compounds in groundwater are broadly and preventively attributed to local anthropogenic pollution, thoroughly disregarding geogenic natural background levels. Particularly landfills, a proper evaluation the significant adverse environmental effects should be completed through detailed characterization, appropriate reference values established prior landfill onset. However, monitoring network may lack full hydrogeological...
Abstract The contribution of oxic methane production to greenhouse gas emissions from lakes is globally relevant, yet uncertainties remain about the levels up which methanogenesis can counterbalance methanotrophy by leading CH 4 oversaturation in productive surface waters. Here, we explored biogeochemical and microbial community variation patterns a meromictic soda lake, East African Rift Valley (Kenya), showing an extraordinarily high concentration waters (up 156 µmol L −1 ). Vertical...
In Mediterranean intermittent streams, the hydrological fragmentation in summer and successive water flow re-convergence autumn allow exploring how local processes shape microbial community within same habitat. The objectives of this study were to determine bacterial composition responded summer, evaluate whether seasonal shifts predominate over effects episodic habitat fragmentation. was assessed along stream Fuirosos (Spain), at different levels phylogenetic resolution by situ...
Understanding DOM transport and reactivity in rivers is essential to having a complete picture of the global carbon cycle. In this study, we explore effects hydrological variability downstream on dissolved organic matter (DOM) dynamics Mediterranean river. We sampled main stem river Tordera from source sea, over range fifteen conditions including extreme events (flood drought). By exploring spatial temporal gradients fluorescence properties, hydrology was found be significant predictor...
Flow cytometry is suitable to discriminate and quantify aquatic microbial cells within a spectrum of fluorescence light scatter signals. Using fixed gating operational settings, we developed finite distribution mixture model, followed by the Voronoi tessellation, resolve bivariate cytometric profiles into cohesive subgroups events. This procedure was applied outline recurrent patterns quantitative changes community along river hydrologic continuum. We found five major each commonly retrieved...
