Genus species

Description and Significance

Description: Strains of colorless, filamentous, gliding bacteria, visible to the naked eye.

Size: Ranging from about 3.0 to 5.0 μm in diameter

Habitat: Lives at the oxic/anoxic interface of aquatic habitats in high concentrations of sulfide reaching toxic levels.

Importance: Due to its ability to detoxify sulfide, this microbe plays a huge role in the sulfur cycle of coastal environments.

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?:

metabolism: the metabolism ranges from obligate chemolithoautotrophy or obligate heterotrophy. there was also a recent discovery of falcutative Methylotrophy within a fresh water strain.

How does it gain energy?:

what important molecules does it produce?:

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.
