Query: NC_008639:1573971 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.

General Information: This species was isolated from the kidney of the earthworm Eisenia foetida. Evidence based on curing experiments, Acidovorax-specific probes, and 16S phylogeny, indicate that earthworm egg capsules contain high numbers of the bacterial endosymbiont. Juvenile earthworms are colonized during embryonic development within the egg capsule, and failing this are not likely to acquire the symbiont by association with colonized adults or their bedding.
