However, a problem was faced after the isolation was incubated.The plate was contaminated and had more than two different bacterium’s growing.It is also important for students to understand sterile techniques, diagnostic steps, treatment, risk assessment, transmission, and prevention of microorganisms.Tags: Free Homework PassesPenghargaan AssignmentNeil Gaiman Sandman EssayAp Biology Plant EssaysThe Wonderful World Of Nature EssayThesis Practice PromptsDna Replication Research PaperEssay On Crucible ThemesCritical EssaysBibliography For Essay In A Book
The first biochemical test performed was a Simmons Citrate, and after observation a negative result was concluded.
This narrowed down the answers to Escherichia coli and Proteus vulgaris.
The next biochemical test that was performed was a H2S test.
After observation, the H2S test had a negative result, which pointed to Escherichia coli.
Culture #1 Biochemical Tests & Results DISCUSSION/CONCLUSION: The first culture’s results were found with the help of the unknown chart, handed out by the instructor.
The unknown tube, #125, was isolated in order to grow two separate cultures.
The two microorganisms were identified; one was a Gram-positive bacteria, the other was a Gram-negative bacteria.
A series of biochemical tests were performed based on the results of the Gram stains.
MATERIALS AND METHODS: The instructor handed out an unknown test tube, labeled as number 125.
The methods and tests learned through out the semester were used on this test tube in order to identify the two unknown microorganism; one a Gram positive and the other a Gram negative.
