Abstract Biological tissues, sediments, or engineered systems are spatially structured media with a tortuous and porous structure that host the flow of fluids. Such complex environments can influence the spatial and temporal colonization patterns of

Abstract Microbially induced calcium carbonate (CaCO3) precipitation (MICP) is one of the major sustainable alternatives to the artificial cementation of granular media. MICP consists of injecting the soil with bacterial- and calcium-rich solutions s

Most porous systems comprise structures characterized by dead-end and transmitting pores. Here, authors show that macroscopic transport through such porous medium is controlled by structure-induced laminar vortices inside each dead-end pore, and such

Summary: Biofilms are surface-attached and matrix-enclosed microbial communities that dominate microbial life in numerous ecosystems. Using flumes and automated optical coherence tomography, we studied the morphogenesis of phototrophic biofilms along

Anaerobic processes (e.g., methanogenesis and fermentation) largely contribute to element cycling and natural contaminant attenuation/mobilization, even in well-oxygenated porous environments, such as shallow aquifers. This paradox is commonly explai

Molecular diffusion in liquids is a key process in numerous systems: it is often the reaction rate limiting factor in biological or chemical reaction. Molecular diffusion has been recognized as the ultimate mechanism by which substances concentration

Bacteria live in heterogeneous environments, so it is important to investigate their behaviour in porous media. Here the authors show that flow disorder enhances the effect of chemical gradients in micropockets in a porous medium, which then aid the

The heterogeneous spatial organization and composition of bacterial communities in soils are expected to deeply impact geochemical quantities at the pore-scale, shaping steep solutes gradients in spite of mixing processes. Oxygen distribution is of m

Permeable systems can accommodate the flow of fluids through their porous structure that is characterized by solid impermeable grains and empty volumes (the pores). Biofilms are complex and heterogeneous aggregates of communities of microorganisms ad
