Query: NC_007519:64157 Desulfovibrio alaskensis G20 chromosome, complete genome
Lineage: Desulfovibrio alaskensis; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria
General Information: This organism is a spontaneous nalidixic acid-resistant derivative of a wild-type strain (G100A) that was isolated from an oil well corrosion site. It has been cured of a 2.3 Kb cryptic plasmid as well. This organism is one of the few extensively studied sulfate-reducing bacteria.
Subject: NC_014817:142976 Asticcacaulis excentricus CB 48 chromosome 2, 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.
