Habitat Information
Describe the location and conditions under which the organism was isolated.
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. On October 20th, 2017; we used LB broth that had been previously cultured the week prior with one small colony of our soil microorganism. Using this broth we performed chemical tests and these were the results: 1. Inoculated Methyl Red and Voges-Proskauer broth to test for fermentation. Result: Negative; it did not produce mixed acid fermentation and it did not convert glucose to neutral end products. 2. Citrate test. Using a Simmons Citrate slant and an inoculating needle stabbed the slant and streaked the slant. Result: Negative; it does not use Citrate as its only carbon source. 3. Sulfur Indole Motility Test (SIM): Result: Negative. It does not produce Indole, it does not reduce sulfur and it is non-motile. 4. Nitrate reduction test. Using a Nitrate broth tube, inoculated with our microorganism. The result of the first step the reaction was Negative; this meant it did not reduce nitrates. So we went to the second step adding Zinc powder. This result was Negative as well; The result is the microorganism does not convert Nitrate to Nitrite neither to other end products. Negative for Nitrate or other end products. 5. Urea Hydrolysis Test. Inoculated a urea broth tube. Result: Negative; it cannot convert Urea to ammonia. 6. Triple Iron Sugar (TSI) test. Inoculateda TSI slant. Our soil microorganism was negative for fermentation.
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.
