Abstract

Symbiodinium microadriaticum were found localized in the mesoglea of Cassiopeia, the upside-down jellyfish. Axenic cultures of the symbiont were produced, utilizing chemically defined media. Studies of the life cycle established the presence of isogametes which had previously been postulated. Reactions to various bands of the spectrum were noted, and tolerance tests for survival in darkness and under temperature stress were carried out. Nutritional experiments established nitrates as the best nitrogen source and verified the fact that vitamins B12 and Thiamine, though not essential far life, hove a stimulating effect on the growth and motility of these zooxanthellae.
