| Abstract: | SYNOPSIS. Algal symbiotes isolated from marine invertebrate hosts, and grown axenically in culture, have been successfully combined in artificial associations with chick fibroblasts and grunt (Haemulon sp.) fin explants. Growth (measured by cell numbers and chlorophyll a) is stimulated in both symbiotes and host cells. Studies of nitrogen uptake and exchange suggest that these artificial associations are similar to other, natural symbioses involving invertebrate hosts, e.g. the hermatypic corals. |
