Description and significance
Prochloron Didemni is a unicellular cyanobacteria that is photosynthetic and oxygenic. It is an obligate symbiont that lives in the ascidian Lissoclinum patella and can be found in marine environments.
The study of Prochloron didemni and its genome can provide us with valuable information. The genome of P. didemni is currently incomplete. However, when completed, P. didemni's genome can be used for analysis to elucidate other genes responsible for symbiosis between bacteria and chordates, such as humans. Also, as a oxygenic, photosynthetic cyanobacteria, P. didemni is a significant player in global carbon fixation. The study of its metabolic pathways and unique photosynthetic processes would yield information beneficial to biotechnology.
R.A. Lewin first discovered Prochloron didemni in 1975, but identified it as Synechocystis didemni. In 1977, the presence of chlorophyll a/b and the lack of phycobilins caused it to be transfered to a new genus, Prochloron, and named Prochloron didemni.(4)
