Webb13 aug. 2004 · Our results clearly suggest that endosymbiotic cyanobacteria capable of fixing nitrogen are present in M. cavernosa and form a stable long-term association within host cells. This symbiont could potentially be a source of the limiting element nitrogen for the symbiosis through the release of fixed nitrogen products to the coral host. Fig. 3.

This review discusses antenna structures, photosynthetic properties and evolutionary relationships among these bacteria, with focus on the role of photosynthesis in their natural habitat. WebbDifferences in the structure of the outer wall layers have been noted when compared to other eubacteria; however, essential thylakoid features are also found in prochlorophytes and eucaryotic algae oxygenic plants. These features emphasize that cyanobacteria and prochlorophytes should be considered a distinctive grouping of the eubacteria. Keywords eating in the mailbox birmingham
