Flavobacterium denitrificans

Description and Significance

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

Appearance: They are gram-negative, motile rods. Habitat: They are found in the gut of the earthworm Aporrectodea caliginosa. Importance: The organism is important because they carry out denitrification.

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.

Mono- and polymeric carbohydrates as well as proteins as electron donors.

Oxygen, nitrate and nitrite were used as electron acceptors but not iron(III) and sulphate.

Uses ammonium as nitrogen source.

N2O is produced as an intermediate during the reduction of NO3- to N2.

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.
