Although filamentous fungal pellets are often exploited in bioprocesses, their inner structure and the resulting diffusion barrier for nutrients, oxygen, and secreted metabolites remained largely unexplored. This thesis presents the first method to determine the micromorphology of pellets including X-ray microcomputed tomography measurements and three-dimensional image analysis. Further, a universal law for the diffusive transport thorugh mycelial networks was revealed based on diffusion computations through measured and simulated structures.
