Habitat Information
B. "subtilis" is commonly found in soil (which explains why it is UV resistant) and in the human gastrointestinal tract. This organism was collected on January 29, 2016. There was 0% rainfall and 22% humidity. GPS coordinates are 30.195412 and -97.75259799999998. The soil came from the front yard about 1” below surface.
Description and Significance
Describe the appearance (colonial and cellular), possible antimicrobial activity etc. of the organism, and why the organism might be significant.
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
Interesting features of cell structure; how it gains energy; what important molecules it produces. Bacillus Subtilis is a prokaryote organism. It is a Gram positive organism meaning it has a thick peptidoglycan layer and a think cytoplasmic membrane. It is a rod-shaped cell that used a flagella for motility. This organism is aerobic meaning when it under goes cellular respiration it uses oxygen as the terminal electron acceptor. However after performing a Nitrate reduction test it proved that bacillus Subtilis can reduce Nitrate and survive under anaerobic conditions. Since this is a soil organism, it is highly resistant to UV rays.
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.
