The freshwater phytoflagellate, Ochromonas danica, secretes a variety of membranous vesicles and macromolecules including carbohydrate, nucleic acidlike molecules, protein (including enzymes), and lipid into its environment. This secretion is confirmed by chemical, spectral, ultrastructural, and differential centrifugal techniques. The significance of this secretion in nature is discussed and another source for the occurrence of organic aggregates in natural waters is suggested.
