Query: NC_008639:2786447 Chlorobium phaeobacteroides DSM 266, complete genome

Lineage: Chlorobium phaeobacteroides; Chlorobium; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria

General Information: Chlorobium phaeobacteroides strain DSM 266 was isolated from a lake in Norway. This species contains several carotenoids, predominated by isorenieratene and beta-isorenieratene. These are necessary for light harvesting and photoprotection, which are important functions in photosynthesis. This species demonstrates a novel type of carotenoid-mediated photoadaptation induced by the change of theta-end and beta-end carotenoid groups, under various light intensities.

Subject: NC_007413:1570000 Anabaena variabilis ATCC 29413, complete genome

Lineage: Anabaena variabilis; Anabaena; Nostocaceae; Nostocales; Cyanobacteria; Bacteria

General Information: These cyanobacteria are bluegreen algae that are capable of fixing carbon and nitrogen. They form long filaments and can be found worldwide in various aquatic environments as well as some terrestrial ones. These bacteria can form a variety of differentiated cell types, including spore-like cells (akinetes), small motile filaments (hormongia) and most importantly, heterocysts that are nitrogen-producing cells. The heterocyst produces multiple layers outside of its cell wall, shuts down photosystem II in order to inhibit oxygenic photosynthesis and ramps up metabolism in order to use up the oxygen present. Heterocysts donate fixed nitrogen compounds as amino acids to neighboring cells and in return receive a photosynthetically produced carbon source such as sucrose. These organisms produce toxic blooms in aquatic environments that are harmful or fatal to animals and humans due to the various cyanotoxins they produce. Anabaena variabilis is a filamentous heterocyst-forming cyanobacterium that fixes nitrogen and CO2 using the energy of sunlight via oxygen-evolving plant-type photosynthesis. In addition, this organism has been studied extensively for the production of hydrogen using solar energy.
