Description and significance

Non-motile, unicellular organism. Free-living (non-symbiotic), Aerobic, chemoheterotrophic bacteria with N2 fixing capabilities. Rod-shaped when young; pear, or dumbbell shaped cells with aging; polar lipoid bodies on each end of the cell. These bacteria are extremely acid tolerant and have been shown to fix more nitrogen as the acidity levels increase (up to 2.7 pH) (Barbosa et. all. 2002) Some studies have shown that while no symbiosis occurs, this bacteria may increase the viability of others in the ecosystem. (Barbosa et. all. 2000)

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 and metabolism

Interesting features of cell structure; how it gains energy; what important molecules it produces.


Ecology

Habitat; symbiosis; contributions to environment.
