Sulfate Utilization in Green Hydra

  • Clayton B. Cook


Recent work on the symbiosis between cnidarians and endosymbiotic algae has demonstrated that algae release soluble photosynthate to a variety of coelenterate hosts (Muscatine, 1974. The flow of organic carbon from algae to animal has reasonably been investigated as a major nutritional benefit of algal symbiosis. Lewis and Smith (1971) have drawn attention to the possibility that other nutrients could be transferred between algae and host. In this paper, I wish to suggest that sulfate may be important in the metabolism of coelenterates which harbor algal symbionts, and I present preliminary evidence which shows that the possession of symbiotic algae enhances the ability of green hydra to metabolize sulfate.
