General Information: UCYN-A cyanobacteria are species of nitrogen-fixing marine cyanobacteria that lack the oxygen producing photosystem II complex of the photosynthetic apparatus, the enzymes of the Calvin and tricarboxylic acid cycles, as well as several enzymes involved in amino acid synthesis. The cyanobacteria live in symbiosis with photosynthetic eukaryotic cells, specifically those of a single-celled species of algae.

General Information: This strain was collected off Hatsushima island in Sagami Bay, Japan. Calyptogena okutanii (deep-sea clam) thioautotrophic gill symbiont. The bivalve marine species Calyptogena okutanii depends on sulfur-oxidizing symbiotic bacteria housed in its gill tissues for its sole nutritional support. The symbiont is transmitted vertically between generations via the clam's eggs. This anaerobic symbiosis oxidizes hydrogen sulfide as an energy source and fixes carbon dioxide into organic compounds.
