ABSTRACT Extracellular release of dissolved organic compounds by the bluegreen algal community of a brackish marsh was studied using 14 C techniques. Mannitol and trehalose were identified as the most commonly released compounds. The proportions of these two extracellular compounds varied in response to light intensity and the water potential of the environment. The presence of mannitol, in particular, suggests that excretion of organic compounds in natural situations is a function of osmotic adjustment.
