Open AccessDesign and construction of 3D printed devices to investigate active and passive bacterial dispersal on hydrated surfaces
To disperse in water-unsaturated environments, such as the soil, bacteria rely on the availability and structure of water films forming on biotic and abiotic surfaces, and, especially, along fungal mycelia. Di...

Open AccessA versatile microfluidic platform measures hyphal interactions between Fusarium graminearum and Clonostachys rosea in real-time
Routinely, fungal–fungal interactions (FFI) are studied on agar surfaces. However, this format restricts high-resolution dynamic imaging. To gain experimental access to FFI at the hyphal level in real-time, we...

Open AccessThe wild-type flagellar filament of the Firmicute Kurthia at 2.8 Å resolution in vivo
Bacteria swim and swarm by rotating the micrometers long, helical filaments of their flagella. They change direction by reversing their flagellar rotation, which switches the handedness of the filament’s super...

Open AccessBiocontrolled soil nutrient distribution under the influence of an oxalogenic-oxalotrophic ecosystem
The oxalate-carbonate pathway (OCP) has been observed in acidic tropical soils with low alkaline cation content where compartments are transient and fed by the rapid turnover of organic matter. By acting on ed...
