A process is provided for the extraction of pigments from immobilized microorganisms. Pigment producing cells are immobilized and dried in a binder matrix, and pigments are recovered from the cells by liquid rinsing. Following release of the pigments, cellular metabolism of the microorganisms is revived in culture medium and pigments are regenerated. Pigments are then recovered from the immobilized cells by successive rounds of dehydration/rinsing/cell recovery.
