11/10:Oxidase

Results for tests from 11/8

            Citrate: Negative for Citrate

            Nitrate: Positive for Nitrate

            Indole: Negative for Indole

Urea: Bacteria grew at bottom, and color was yellow which means it does not break down urea.

Antibiotic Test: To determine if the antibiotics kill our bacteria. The measurements determine whether the bacteria is sensitive to the antibiotic.

            Antibiotics that break down cell wall

1)   Penicillinà 0mm

2)   Vancomycinà 20 mm

Nucleic Acid

3)   Novabiocinà 29 mm

Protein

4)   Tetracyclineà 15 mm

5)   Erythromycinà 34 mm

6)   Chloramphenitolà 29 mm

7)   Neomycinà 20 mm

The next test we did was the oxidase test to determine if our bacteria has cytochrome oxidase, which is an enzyme. When we inoculated it, it turned purple, therefore it his cytochrome oxidase.
