Query: NC_011886:2950411 Arthrobacter chlorophenolicus A6, complete genome
Lineage: Arthrobacter chlorophenolicus; Arthrobacter; Micrococcaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Arthrobacter chlorophenolicus A6 (DSM 12829) was isolated from soil at Fort Collins, Colorado, USA and is able to use 4-chlorophenol as a sole source of carbon and energy. This organism can degrade 4-chlorophenol in soil at temperatures ranging from 5 to 28 degrees C making it a good candidate for bioremediation. Arthrobacter chlorophenolicus can degrade high concentrations of para-substituted phenols, such as 4-chlorophenol and 4-nitrophenol and can survive under harsh conditions, such as cold temperature and during starvation in soil.
Subject: NC_002932:440191 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.
