Query: NC_014032:1408967 Salinibacter ruber M8 chromosome, complete genome
Lineage: Salinibacter ruber; Salinibacter; Rhodothermaceae; Bacteroidetes Order II; Bacteroidetes; Bacteria
General Information: Salinibacter ruber (strain M8) is a brightly red-pigmented, motile, rod-shaped, extremely halophilic Gram-negative bacterium isolated from a saltern crystallizer pond in Mallorca, Spain. It grows optimally at salt concentrations between 20 and 30% and does not grow below 15% salt. S. ruber is among the most halophilic organisms known within the domain Bacteria. This organism is an extremely halophilic aerobe originally isolated from saltern crystallizer ponds in Spain. These bacteria can coexist in significant colonies with halophilic archaea under saline conditions. In contrast to other bacteria they do not regulate their intracellular salt conditions through proton pumps, but instead their protein makeup has adapted to be functional under high ionic conditions.
Subject: NC_008148:2156873 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.
