CLSM micrograph of LIVE/DEAD stained R. palustris entrapped in PVA cryogel bead following 24 h cultivation in minimal media under illumination. Image presents entire cross-section through centre of a single PVA cryogel bead. Membrane-intact cells are represented by green fluorescence (Syto9) and membrane-compromised cells in red (propidium iodide). Yellow inclusions are non-bacterial debris as artefact of immobilisation process. Image contrast enhanced for visibility equally across all channels
