Query: NC_008148:258292 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_011901:1860887 Thioalkalivibrio sulfidophilus HL-EbGr7 chromosome, complete

Lineage: Thioalkalivibrio sulfidophilus; Thioalkalivibrio; Ectothiorhodospiraceae; Chromatiales; Proteobacteria; Bacteria

General Information: Obligately chemolithoautotrophic, haloalkaliphilic, mesophilic, microaerophilic and sulfur-oxidizing bacterium. Uses CO2 as a carbon source and reduced inorganic sulfur compounds as an energy source. Utilizes ammonium and urea, but not nitrate or nitrite, as a N-source. Isolated from a full-scale Thiopaq bioreactor in the Netherlands used to remove H2S from biogas. Thioalkalivibrio species are commonly isolated from soda lakes and tend to dominate the microbial community of hypersaline soda lakes. These organisms have a pH optimum of 10 and are able to oxidize hydrogen sulfide to elemental sulfur. Thioalkalivibrio species have also been isolated from sulfide oxidizing bioreactors which remove sulfide from refinery and natural gas.
