Habitat Information
Describe the location and conditions under which the organism was isolated. The dirt sample that the B. cereus came from was collected on September 3, 2015 in Lakeway, Texas. The dirt was in a shady area underneath some trees between a creek and a small field. It was 91 degrees Fahrenheit, 44% humidity, and had not rained in the past 24 hours. The dirt was collected from about 2 inches below the surface. Approximate grid coordinates from the NRCS soil map are 3359230 x 598060. Soil type according to the NRCS soil map is volente silty clay loam, 1 to 8% slopes.
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: Matt, white, flat colonies with irregular to lobate margins. Cellular appearance: Rod-shaped, endospore forming, and Gram-positive.
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.
B. Cereus is:
