The laboratory manual, by Mc Donald, includes all the procedures used for these methods (1). This was completed by taking an inoculating loop and spreading the unknown out on to a Nutrient Agar plate.
This was done using the streak plate method, which is described in the lab manual.
However, a problem was faced after the isolation was incubated.
The plate was contaminated and had more than two different bacterium’s growing.
Here is an excellent example of how to write an unknown lab report in Microbiology class.

Please note that due to formatting issues the flow charts had to be removed. All healthcare providers ultimately have to take a microbiology class as part of their program curriculum.From there, each colony was isolated, incubated and grown on separate plates.After the morphology was observed and recorded, a Gram stain was performed on each, this procedure is found in the laboratory manual.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 next biochemical test that was performed was a H2S test.After observation, the H2S test had a negative result, which pointed to Escherichia coli.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 tables below illustrate the tests used for each unknown microorganism.The flow charts show how the conclusions were reached.
