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

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? 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.
