Query: NC_010831:173499 Chlorobium phaeobacteroides BS1, complete genome

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

General Information: Photosynthetic microorganism. 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_010337:2339056 Heliobacterium modesticaldum Ice1, complete genome

Lineage: Heliobacterium modesticaldum; Heliobacterium; Heliobacteriaceae; Clostridiales; Firmicutes; Bacteria

General Information: Heliobacterium modesticaldum strain Ice1, the type strain of this species, was isolated from Icelandic hot spring volcanic soils. It grows optimally above 50 degrees Celsius, grows best photoheterotrophically, but can grow in the dark chemotrophically on pyruvate. Phototrophic thermophile. This organism is an anoxygenic phototroph isolated from hot spring microbial mats and volcanic soil. Cell wall structure, the ability to form endospores, and 16S ribosomal RNA analysis place Heliobacterium modesticaldum in a family of phototrophic bacteria related to the Clostridia. Heliobacterium modesticaldum is able to fix nitrogen and may contribute significantly to the nitrogen availability in microbial mats.
