Azotobacter chroococcum

Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Azotobacter chroococcum colonies are characterized by a creamy color, circular shape, and smooth convex type. Single bacterium are characterized by a rod shape and are motile by way of a flagella (Talabani et al. 2019).

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.
