NCBI: Taxonomy

Genus species

  • Terrabacteria Group

Molecule Type

  • Nucleic Acid

Habitat Information

  • Types of Soil Organism was Found In:
 Heiden Clay, 5-8% slopes, eroded (most common)
 Houston Black Clay, 1-3% slopes

Air Temp: 83 Degrees Fahrenheit/ 28 Degrees Celsius Humidity: 32 % 24 hr. Rainfall: 0.00in Pressure: 30.11 in/ 1018.5mb (sea level) Solar Radiation: 22.49 (mj/m^2) Wind at 4am: 2.06mph Wind at 4pm: 2.77mph

  • Soil Location Description:
Soil was taken from directly under a tree at Cabana Beach Apartments in San Marcos, Texas. This area is a very open area and gets water daily from sprinklers. The water it gets daily is minimal, so it does dry quickly. The soil was a very dark brown color. Had almost a dry dirt look and feel to it.


Description and Significance

  • Description:
Whiteish color, shiny, raised and semi flat

Most common similar Bacteria: Bacillus Safensis:

 Gram-positive, spore-forming, and rod bacterium
Bacillus Safensis is a Gram-positive, spore-forming rod bacterium. Bacillus safensis is also an aerobic, chemoheterotroph. Cell size ranges from 0.5-0.7 μm in diameter and 1.0-1.2 μm in length. Bacteria are motile, and use polar flagella for locomotion. Cells are considered mesophillic, as they can grow in temperatures ranging between 10-50 °C
It was first discovered in California and Florida on spacecraft and so is believed to have been brought to the USA from Mars. There are numerous strains of this bacterium, everyone belonging to the Firmicutes phylum of Bacteria. This organism is significant because it can tell us a bit about other planets and also how the bacteria spreads. It is also resistant to UV rays, gamma rays and is highly salt resistant, therefore it makes for a great plant growth-promoting rhizobacteria.

Genome Structure


  • Species Most Similar:

- Bacillus Zhangzhouensis Strain Tr91C - Bacillus Zhangzhouensis Strian KBA10 - Bacillus Pumilus - Bacillus Safensis - Uncultured Bacillus

Cell Structure, Metabolism and Life Cycle

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

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.
