Query: NC_007973:2952004 Ralstonia metallidurans CH34 chromosome 1, complete sequence
Lineage: Cupriavidus metallidurans; Cupriavidus; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This strain was first identified in the heavy metal-contaminated sludge of a settling tank in Belgium in the late 1970s. This organism, formerly Ralstonia metallidurans, is capable of growth in the presence of a large number of heavy metals including silver, cadmium, chromium, cobalt, copper, mercury, nickel, lead, thallium, and zinc.
Subject: NC_014816:2446236 Asticcacaulis excentricus CB 48 chromosome 1, complete sequence
Lineage: Asticcacaulis excentricus; Asticcacaulis; Caulobacteraceae; Caulobacterales; Proteobacteria; Bacteria
General Information: Environment: Fresh water; Isolation: Pondwater; Temp: Mesophile; Isolation: pond water. Asticcacaulis excentricus inhabits aquatic environments and plays an important part in biogeochemical cycling of organic nutrients. This bacterium undergoes an unusual developmental cycle in which a swarming motile cell becomes a stalked cell that is attached to a solid surface. The stalked cell then undergoes asymmetric cell division and produces one flagellated motile daughter cell and one stalked daughter cell. Thus, the asymmetric processes in this organism provide useful models for differentiation and development.
