Query: NC_008148:583030 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.

Subject: NC_015052:2181514 Bifidobacterium longum subsp. infantis 157F, complete genome

Lineage: Bifidobacterium longum; Bifidobacterium; Bifidobacteriaceae; Bifidobacteriales; Actinobacteria; Bacteria

General Information: This organism is found in adult humans and formula fed infants as a normal component of gut flora. Representatives of this genus naturally colonize the human gastrointestinal tract (GIT) and are important for establishing and maintaining homeostasis of the intestinal ecosystem to allow for normal digestion. Their presence has been associated with beneficial health effects, such as prevention of diarrhea, amelioration of lactose intolerance, or immunomodulation. The stabilizing effect on GIT microflora is attributed to the capacity of bifidobacteria to produce bacteriocins, which are bacteriostatic agents with a broad spectrum of action, and to their pH-reducing activity.
