Bacillus pumilus
Habitat Information
B. pumilus can be found in a wide variety of soils, plants, and surfaces. My particular sample was found in an area of Lewisville soils and Urban land, with 0 to 2 percent slopes. The temperature and humidity when the sample was taken were 73º F and 22%. Pressure was 30.03 in. and the solar radiation was at 17.55 MJm2. There had been no rainfall in the previous 24 hours. The specific location was a grassy area between my apartment building and the parking lot. The address is 2703 Manor Rd, Austin, TX, 78722.
Description and Significance
Colonial morphology: B. pumilus colonies are opaque and off-white. They are roughly circular, but with an irregular margin, and have a filamentous appearance.
Cellular morphology: B. pumilus is a gram positive rod bacterium with endospores.
B. pumilus can inhibit nematodes and fungal diseases once it colonizes a plant's root system. In fact, strain GB34 is used as an active ingredient in agricultural fungicides. It is also being evaluated for use in the commercial production of cellulase, which is an enzyme that can convert cellulolytic (plant) materials into soluble sugars or solvents.
Genome Structure
B. pumilus has a single circular chromosome. There are 3,681 protein genes and 93 RNA genes for a total of 3,704,465 nucleotides. 41% of its base pairs are G-C.

Cell Structure, Metabolism and Life Cycle
B. pumilus is a gram positive bacterium that forms endospores.
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.
