Bacillus Nealsonii
Habitat Information
This organism was first isolated in a spacecraft-assembly facility from fallen dust particles in 1999 in California.
I discovered this species in the dirt under and rock on a walking trail in San Marcos Texas.
Description and Significance
Describe the appearance (colonial and cellular), possible antimicrobial activity etc. of the organism, and why the organism might be significant. Colony appearance: Colonies are round to irregular, with entire margins, colonies may be a creamy white to pale yellow color. Cellular appearance: It is a Gram-positive, facultatively anaerobic, rod-shaped eubacterium that produces endospores This bacteria has no antimicrobial properties. This organism is significant because it is resistant to gamma-gradation, UV, H2O2, and desiccation, and has caused no human disease.

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? Include S Ribosomal sequence that you obtained from PCR and sequencing here.
Cell Structure, Metabolism and Life Cycle
Metabolism, more specifically catabolism, is the process where an organism breaks down organic material for the production of energy.
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.
