We found that depletion of nitrates ceased cell division and caused rapid accumulation of lipids in the microalga Chlorella vulgaris. We described in detail both biogenesis and mobilization of lipid bodies using fluorescence and transmission electron microscopy. Small lipid bodies fused forming one huge lipid body occupying most of the cell volume in stationary growth phase. After replenishment of nitrogen, lipid content decreased rapidly and, within 24 hours, the large lipid body was fragmented into smaller ones. This mobilization of the cellular lipid store occurred independently of light.
