Publikováno v: Environmental Microbiology. 17:1991-2005

The aim of the study was to understand the effect of a long-term metal exposure (110 years) on sediment microbial communities. Two freshwater sites, Ferin and MetalEurop, differing by one order of magnitude in metal levels (MetalEurop: 3218 mg Zn kg(

Oceanic fronts: transition zones for bacterioplankton community composition

Autor: Federico, Baltar, Kim, Currie, Esther, Stuck, Stéphanie, Roosa, Sergio E, Morales

Publikováno v: Environmental microbiology reports. 8(1)

Oceanic fronts are widespread mesoscale features that exist in the boundary between different water masses. Despite the recognized importance of bacterioplankton (including bacteria and archaea) on the marine biogeochemical cycles and the ubiquitousn

The bioavailability of metals was estimated in three river sediments (Sens,e, Scarpe, and DeA >> le Rivers) impacted by different levels of Cu, Cd, Pb, and Zn (Northern France). For that, a combination of geochemistry and biological responses (bacter
