Scheme of the experimental setup for oxygen microprofiling in biopellets (blue encircled close-up) of filamentous microorganisms. Pellet analysis occurs in a glass tube (laminar flow conditions) with the help of oxygen micro-sensors fixed on a software-controlled micromanipulator (MM). Oxygen concentration is measured in 10 µm step sizes inside the pellet.
