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.

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.

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.
