Description and Significance
Candidatus Soilbacter usitaus was initially isolated from rotationally grazed pasture of perennial ryegrass and white clover in Victoria, Australia (1). This species is common and very prevalent in its environment. It was found to be the most common organism in a study conducted in 2012 analyzing bacterial composition of Antarctic soil (2).
This species has been difficult to culture in the lab. Filaments have been observed microscopically in soils, but it was found to form clusters in liquid culture (3). In nature, this species produces a biofilm that acts as an ecosystem engineer in soil. It does this by acting as a medium between soil particles to reduce moisture and nutrient fluxuations as well as aid in resource acquisition, which serves to aid survival under environmental stress conditions (4).
This species has an exceptionally large genome and is theorized to engage in horizontal gene transfer which contributes to this species ability to persist in its environment. It is theorized to be capable breaking down plant compounds for metabolism, and to participate in respiratory denitrification which lends to the creation of heterogeneous nutrient concentrations in its environment (4).
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
