Query: NC_002932:296557 Chlorobium tepidum TLS, complete genome

Lineage: Chlorobaculum tepidum; Chlorobaculum; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria

General Information: This green-sulfur bacterium is a thermophile and was isolated from a New Zealand high-sulfide hot spring. Photosynthetic thermophile. Chlorobium tepidum is a member of the green-sulfur bacteria. It has been suggested that the green-sulfur bacteria were among the first photosynthetic organisms since they are anaerobically photosynthetic and may have arisen early in the Earth's history when there was a limited amount of oxygen present. This organism utilizes a novel photosynthetic system, and harvests light energy using an unusual organelle, the chlorosome, which contains an aggregate of light-harvesting centers surrounded by a protein-stabilized galactolipid monolayer that lies at the inner surface of the cytoplasmic membrane. Unlike many other photosynthetic organisms, the green-sulfur bacteria do not produce oxygen and tolerate only low levels of the molecule. This organism also fixes carbon dioxide via a reverse tricarboxylic acid cycle, using electrons derived from hydrogen or reduced sulfur to drive the reaction, instead of via the Calvin cycle like many other photosynthetic organisms.

Subject: NC_010725:2589014 Methylobacterium populi BJ001, complete genome

Lineage: Methylobacterium populi; Methylobacterium; Methylobacteriaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This species was isolated from tissue cultures of Populus, the Poplar tree. Colonies are pink to red, and the red pigment is water insoluble. Species of the genus Methylobacterium are strictly aerobic, facultatively methylotrophic, Gram-negative, rod-shaped bacteria that are able to grow on one-carbon compounds (e.g. methanol or methylamine), as well as on a variety of C2, C3 and C4 substrates. Only the type species, Methylobacterium organophilum, has been shown to use methane as the sole source of carbon and energy. Members of the genus are distributed in a wide variety of natural and man-made environments, including soil, air, dust, fresh- and marine water and sediments, water supplies, bathrooms, air-conditioning systems and masonry, and some are opportunistic human pathogens.
