Unit 3 Unknown Identification assignment: Assume that an unknown sample containing two unknown bacteria was submitted to a lab; Gram staining and biochemical tests were completed. You are provided with the lab results, and you have been asked to interpret the results and identify the unknown bacteria down to genus and species. Complete parts one and two to complete the assignment.
PART ONE:
1) Review the unknown identification video linked in the assignment section.
2) Consult the unknown charts below, and interpret the lab results. Fill in the “interpretation” column after considering the observations from the lab. Consult the “unknown identification guide” in the assignment section for assistance with the biochemical tests.
3) Identify the unknown genus and species and record it in the last row of the chart.
4) Answer the questions that follow the results charts.
5) Include references and citations for any sources consulted.
6) Submit your assignment in a word document to the Unit 3 assignment Dropbox. For full instructions, consult the assignment section in unit 3.

PART TWO:
Answer the following questions, providing enough discussion to thoroughly answer each question.
1. Explain the process you followed to identify your unknowns.
2. If you were just to complete the Gram stain in the identification process, would you be able to differentiate between your two unknown species? Why or why not?
3. If you were growing each organism in a lab, what carbohydrate source(s) would you add to the medium to ensure proper growth (Hint: check the fermentation results for each unknown)?
4. If you wanted to disinfect a surface that was contaminated with your unknowns, which type of disinfectant would you use for each, and why?
