Query: NC_009718:799431 Fervidobacterium nodosum Rt17-B1, complete genome
Lineage: Fervidobacterium nodosum; Fervidobacterium; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: Fervidobacterium nodosum is a thermophilic, Gram-negative, motile, non-sporulating, glycolytic, obligately anaerobic rod that exists singly, in pairs or in chains. Fervidobacterium nodosum was isolated from a hot spring in New Zealand. Its optimal growth temperature is 65 to 70 degrees Celsius. The cellular morphology of this organism, a member of the Thermotogales, is characterized by a terminal spherical extension of the cell envelope.
Subject: NC_002696:2829002 Caulobacter crescentus CB15, complete genome
Lineage: Caulobacter vibrioides; Caulobacter; Caulobacteraceae; Caulobacterales; Proteobacteria; Bacteria
General Information: Bacterium that undergoes asymmetric cell division and differentiation. Caulobacter vibroides, also known as Caulobacter crescentus, 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. This organism also contains a number of energy-dependent transport system, presumably enabling growth in the substrate-sparse aquatic environments that it lives in.
