Query: NC_007205:1232734 Candidatus Pelagibacter ubique HTCC1062, complete genome
Lineage: Pelagibacter ubique; Pelagibacter; Pelagibacteraceae; Rickettsiales; Proteobacteria; Bacteria
General Information: They were originally named SAR11 and known only from their rRNA genes, which were first identified in environmental samples from the Sargasso Sea in 1990. P. ubique are possibly the most numerous bacteria in the world.
Subject: NC_008148:2498000 Rubrobacter xylanophilus DSM 9941, complete genome
Lineage: Rubrobacter xylanophilus; Rubrobacter; Rubrobacteraceae; Rubrobacterales; Actinobacteria; Bacteria
General Information: Cellulose-degrading bacterium. This genus contains two species: Rubrobacter radiotolerans and Rubrobacter xylanophilus. These two species represent the oldest lineage (deepest branch) of the Actinobacteria and are distantly related to Mycobacteria and Streptomycetes. Both species are thermophilic and exhibit high tolerance to radiation. Very little research has been done on these organisms and little is known other than their taxonomic characterization. Rubrobacter xylanophilus was isolated from a thermally polluted industrial runoff in the United Kingdom. Some strains of this species are capable of degrading hemicellulose and xylan (polymers of plant origin), and could play a significant role in the degradation of these compounds in the wood and paper industry as well as in the environment.
