Description and Significance

Bacillus cereus F is a strain related to the widely known Bacillus cereus species. This is a gram positive, rod shaped, spore forming species and usually aerobic or facultatively anaerobic. This strain of the organism is important because of its surprising location when found and its presumed age. The viable strain 'F' of Bacillus cereus was found in the permafrost of the Mammoth Mountain in Siberia and is aged to be a bout 3 million years old. This is a great example to be studied for low-temperature adaptations.

Genome Structure

The genome of B. cereus F is not yet fully understood, but its close family member, Bacillus cereus, has a genome comprised of a single circular chromosome consisting of 5,221,581 bp. It has a nucleotide sequence of 398,050.

Cell Structure, Metabolism and Life Cycle

Bacillus cereus F is a gram positive and rod-shaped microbe. It is anaerobic and spore forming. This bacterium produces toxins that can cause vomiting symptoms if ingested. These toxins are include: hemolysins, phospholipases and pore-forming enterotoxins.

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.
