Query: NC_016114:2960989 Streptomyces flavogriseus ATCC 33331 chromosome, complete genome
Lineage: Streptomyces pratensis; Streptomyces; Streptomycetaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Environment: Soil; Isolation: Soil; Temp: Mesophile. The genus Streptomyces consists of soil and water Gram positive filamentous bacteria well known for their ability to produce complex secondary metabolites including many antibiotics. Additionally they undergo complex multicellular development, with spores germinating to form a branched, multinucleoid substrate mycelium, which then produces an aerial mycelium which septates into uninucleoid spores. Streptomyces flavogriseus is an aerobic, Gram-positive bacterium isolated from soil. This organism produces cellulases and xyanases that are able to degrade cellulose and xylan.
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.
