Koudeaccus is a fictional genus of psychrophilic bacteria used in thought experiments and educational scenarios about extremophiles. In the hypothetical taxonomy, it is placed within the domain Bacteria, phylum Proteobacteria, class Alphaproteobacteria, family Cryoaceae, with the type species Koudeaccus frigidus. Other proposed species include Koudeaccus glacialis and Koudeaccus neoterus.
Description: Cells are rod-shaped, 0.6–1.5 μm long; Gram-negative; non-motile or motile by a single polar flagellum.
Habitat and ecology: In the fictional scenario, Koudeaccus is associated with perennially cold environments such as
Discovery and etymology: The genus name combines the Dutch word koude for cold with the Latin acus
Significance: As a hypothetical organism, Koudeaccus serves to illustrate adaptation strategies to cryo-environments, including cold-adapted enzymes
