Grossmont College Identification of the Unknown Bacterium Discussion

 

I will provide you with the results of the biochemical tests and Gram stain of your unknown bacteria. Use the grid to determine the identity of your unknown organism. After determining your unknown organism, go to the NCBI website and pick a journal article that talks about your unknown organism. Pick an article that is relevant and no older than 5 years from the date of publication. Read the entire article and summarize the contents of the article in your own words (do NOT copy the abstract of the article). Submit the summary of the article and a link to the article to me together with the correct identification of your unknown bacteria. The due date for unknown #3 is 4/15/21. No late submission will be accepted. Early submission is acceptable. No handwritten reports will be accepted. Reports should be in the doc, docx, or pdf format.

Here is the link to NCBI PubMed:

https://www.ncbi.nlm.nih.gov/pubmed/ (Links to an external site.)

Rubric: 15 pts for correct identification of unknown bacterium and another 15 points for summarizing a relevant article related to unknown bacterium with proper citation.

Here are the results of your biochemical tests for Unknown #3:

Indole test from SIM: No red ring produced on top of media after adding Kovac’s reagent

H2S test from SIM: No black precipitate was produced after 48 hr incubation

Phenol Red mannitol test: Media turned yellow and no bubble in the Durham tube

Citrate test: Media turned blue after 48 hr incubation

Gram stain: negative

Cell Morphology: rods

Oxygen requirement: facultative anaerobe
