Deciphering the microbiota compositions of complex biofilms from hospital and domestic settings across Estonia, Germany, and the United Kingdom Open
Currently, there is a limited understanding of the microbiota composition of complex biofilms, in particular describing the abundance of bacterial genera, fungi, and yeasts with reference to the One Health axes. As a starting point, descri…

Water Column Microbial Communities Vary along Salinity Gradients in the Florida Coastal Everglades Wetlands Open
Planktonic microbial communities mediate many vital biogeochemical processes in wetland ecosystems, yet compared to other aquatic ecosystems, like oceans, lakes, rivers or estuaries, they remain relatively underexplored. Our study site, th…

<i>Sulfurimonas</i> subgroup GD17 cells accumulate polyphosphate under fluctuating redox conditions in the Baltic Sea: possible implications for their ecology Open
The central Baltic Sea is characterized by a pelagic redox zone exhibiting high dark CO2 fixation rates below the chemocline. These rates are mainly driven by chemolithoautotrophic and denitrifying Sulfurimonas GD17 subgroup cells which ar…
