Query: NC_009954:117895 Caldivirga maquilingensis IC-167, complete genome
Lineage: Caldivirga maquilingensis; Caldivirga; Thermoproteaceae; Thermoproteales; Crenarchaeota; Archaea
General Information: Hyperthermophilic crenarchaeota. Caldivirga maquilingensis was isolated from an acidic hot spring in the Philippines. It is a microaerophilic heterotroph and is able to use sulfur, thiosulfate, and sulfate as electron acceptors.
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.
