Classification
Domain: Bacteria, Phylum: Firmicutes, Class: Bacilli, Genus: Exiguobacterium, Species: Unknown
Habitat Information
This soil organism was collected in the Hill Country of Fredericksburg, Texas. The soil was very soft and moist, about 5-6" in depth.
There are at least 11 different strains of exoquibacterium, the first being discovered in a potato plant by Collins et al. in 1983. Since that time, others have been found in the Siberian frost, glaciers in Greenland, Yellowstone National Park hot springs and various other locations of extreme temperatures.
Description and Significance
Exiguobacterium are small, irregular rod shaped bacteria, or coccobacilli. Stains performed on our organism revealed a positive gram stain and small capsules. This organism was negative for endospores. The ability of exiguobacterium to survive in extreme temperatures (-12C - 55C) and grow within a large range of pH (5-11) make this bacteria an important area of study. It has also shown to be tolerant of UV radiation and heavy metal stress.

Physiology and Pathogenesis
Biochemical characteristics, enzymes made, other characteristics that may be used to identify the organism; contributions to environment (if any).
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Possible antimicrobial activity – At least species one of the Exiguobacterium genus may aid in the digestion of plastics by mealworms. http://www.ncbi.nlm.nih.gov/pubmed/26390390
