Description and Significance
Describe the appearance (colonial and cellular), possible antimicrobial activity etc. of the organism, and why the organism might be significant. The colonial appearance possesses a plaque color with no extracellular pigment. On a plate there is a plateu elevation and smooth margins. The colony has a bad smell to it. The colonies also form in a wide shape. The cellular appearance of the bacteria is rod-shaped and has a pinkish-blue color under a microscope. It is a motile organism. B. subtilis is gram positive and aerobic and catalase positive.
B. subtilis is significant because B. subtilis is considered to be the best Gram-positive bacterium ever studied and is a model organism in the study of bacterial chromosome replication and cell differentiation. It is also able to transform itself into a dormant state in order to survive extreme environments, allowing it to be the longest bacteria to survive in space; it survived six years on a NASA satellite.
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.
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.
