A process for the isolation of crystalline carotenoid compound from microbial biomass comprising disrupting the microbial cell walls, separating cellular debris from the carotenoid-containing residue, washing one member of the group consisting of the microbial biomass, the disrupted cell mass and the carotenoid-containing reside with a solvent to remove lipid, suspending the obtained carotenoid crystals in water to float the crystals, recovering the crystals and, optionally, further purifying the crystals which avoids the use of large amounts of solvent of carotenoid extraction process.
